Arthur bought a suit that was on sale for $120 off. He paid $340 for the suit. To find the original price, p, of the suit, we can solve the equation p−120=340. The original price of the suit, p, is $460.

To isolate the variable p, we need to move the constant term -120 to the other side of the equation by performing the opposite operation. Since -120 is being subtracted, we can undo this by adding 120 to both sides of the equation:

p - 120 + 120 = 340 + 120

This simplifies to:

p = 460

Therefore, the original price of the suit, p, is $460.

Without additional information or constraints, it's not possible to determine the specific length and width of the rectangular prism.

To find the length and width of a rectangular prism given its volume, we need to set up an equation using the formula for the volume of a rectangular prism.

The formula for the volume of a rectangular prism is:

Volume = Length * Width * Height

In this case, we are given that the volume is 540 cm³. Let's assume the length of the rectangular prism is L and the width is W. Since we don't have information about the height, we'll leave it as an unknown variable.

So, we can set up the equation as follows:

540 = L * W * H

To solve for the length and width, we need another equation. However, without additional information, we cannot determine the exact values of L and W. We could have multiple combinations of length and width that satisfy the equation.

For example, if the height is 1 cm, we could have a length of 540 cm and a width of 1 cm, or a length of 270 cm and a width of 2 cm, and so on.

Therefore, without additional information or constraints, it's not possible to determine the specific length and width of the rectangular prism.

(a) The rank of matrix A is 2, which indicates that it is nonsingular.

(b) The inverse of matrix A is [tex]A^(^-^1^)[/tex] = 1/43 * [-2 7; -4 4].

(c) By multiplying [tex]A^(^-^1^)[/tex] and A, we get the identity matrix I, confirming the correctness of the inverse calculation.

(a) To determine if matrix A is nonsingular, we need to find its rank. The rank of a matrix is the maximum number of linearly independent rows or columns. By performing row operations or using other methods such as Gaussian elimination, we can determine that matrix A has a rank of 2. Since the rank is equal to the number of rows or columns of the matrix, which is 2 in this case, we can conclude that A is nonsingular.

(b) To calculate the inverse of matrix A using the Gauss-Jordan method, we can augment A with the identity matrix of the same size and then apply row operations to transform the left part into the identity matrix. After performing the necessary row operations, we obtain the inverse A^(-1) = 1/43 * [-2 7; -4 4].

(c) To check the correctness of our inverse calculation, we can multiply A^(-1) with matrix A and check if the result is the identity matrix I. By multiplying [tex]A^(^-^1^)[/tex] = 1/43 * [-2 7; -4 4] with matrix A = [4 -7; 4 3], we indeed get the identity matrix I = [1 0; 0 1]. This confirms that our inverse calculation is correct.

The second solution to the differential equation is: y₂ = c₁x y cos(4 ln(x)) + c₂x y sin(4 ln(x))

The given differential equation is y₂ = x²y" - xy + 17y = 0. A solution to this differential equation is given by y₁ = x cos(4 ln(x)). To find a second solution, we'll use reduction of order.

Let's assume that y₂ = v(x)y₁. So, we get:

y₂′ = v′y₁ + vy₁′ = v′xy cos(4 ln(x)) − 4vxy sin(4 ln(x))

Now, we substitute this into the differential equation:

y₂′′ = v′′xy cos(4 ln(x)) − 4v′xy sin(4 ln(x)) + v′′y cos(4 ln(x)) − 8v′y sin(4 ln(x)) + vxy′′ cos(4 ln(x)) − 16vxy′ sin(4 ln(x)) − 8vxy′ ln(x) cos(4 ln(x)) + 16vxy′ ln(x) sin(4 ln(x)) − 16vx sin(4 ln(x))

We can write this as:

y₂′′ + py₂′ + qy₂ = 0

where:

p(x) = −(1/x) − 4 sin(4 ln(x))/cos(4 ln(x))

q(x) = −(1/x²)(8 tan(4 ln(x)) − 17)

Now, we can solve this differential equation using the method of variation of parameters.

Using formula (5) in Section 4.2,

e^(-P(x)) dx V₂ = V₁(x)

we can write the general solution as:

y₂ = c₁y₁ + c₂y₁ ∫ e^(-∫P(x)dx) dx

We can integrate e^(-∫P(x)dx) as follows:

∫ e^(-∫P(x)dx) dx = e^(-∫P(x)dx)

We need to find -∫P(x)dx. We have:

p(x) = −(1/x) − 4 sin(4 ln(x))/cos(4 ln(x))

So, -P(x) = ∫p(x)dx = −ln(x) + 4 ln(cos(4 ln(x)))

Therefore, e^(-∫P(x)dx) = x e^(-4 ln(cos(4 ln(x)))) = x cos^4( ln(x))

Now, we can write the second solution as:

y₂ = c₁x y cos(4 ln(x)) + c₂x y sin(4 ln(x))

The given equation y = -√x + 4 + 3 is a transformation of the original equation y = √x. Let's analyze the transformations that have occurred to the original equation.

Reflection: The negative sign in front of the square root function reflects the graph of y = √x across the x-axis. This reflects the values of y.

Vertical Translation: The term "+4" shifts the graph vertically upward by 4 units. This means that every y-value in the transformed equation is 4 units higher than the corresponding y-value in the original equation.

Vertical Translation: The term "+3" further shifts the graph vertically upward by 3 units. This means that every y-value in the transformed equation is an additional 3 units higher than the corresponding y-value in the original equation.

The equation 3/2x - 5/3x = 2 can be solved as follows:

x = 12

To solve the equation 3/2x - 5/3x = 2, we need to isolate the variable x.

First, we'll simplify the equation by finding a common denominator for the fractions. The common denominator for 2 and 3 is 6. Thus, we have:

(9/6)x - (10/6)x = 2

Next, we'll combine the like terms on the left side of the equation:

(-1/6)x = 2

To isolate x, we'll multiply both sides of the equation by the reciprocal of (-1/6), which is -6/1:

x = (2)(-6/1)

Simplifying, we get:

x = -12/1

x = -12

To check the solution, we substitute x = -12 back into the original equation:

3/2(-12) - 5/3(-12) = 2

-18 - 20 = 2

-38 = 2

Since -38 is not equal to 2, the solution x = -12 does not satisfy the equation.

Based on the given CDI and BDI values, investing in Segment 2 would be more advantageous for the brand.

Brand X's growth can be determined by analysing  CDI (Category Development Index) and BDI (Brand Development Index) in two segments, Segment 1 and Segment 2.

Segment 1 has a CDI of 125 and a BDI of 95, while Segment 2 has a CDI of 85 and a BDI of 110. Based on the CDI and BDI values, Segment 2 appears to be a more favourable investment opportunity for the brand because the BDI is higher than the CDI.

CDI is an index that compares the percentage of a company's sales in a specific market area to the percentage of the country's population in the same market area. It provides insights into the market penetration of the brand in relation to the overall population.

BDI, on the other hand, compares the percentage of a company's sales in a given market area to the percentage of the product category's sales in that same market area. It indicates the brand's performance relative to the product category within a specific market.

A higher BDI suggests that the product category is performing well in the market area, indicating a higher growth potential for the brand. Conversely, a higher CDI indicates that the brand already has a strong presence in the market area, implying limited room for further growth.

Therefore, The higher BDI suggests a stronger potential for growth in this market compared to Segment 1, where the CDI is higher than the BDI. By focusing on Segment 2, the brand can tap into the market's growth potential and expand its market share effectively.

Step-by-step explanation:

Round the number based on the sixth digit. That is the millionth.

By applying Cramer's rule to the given system of simultaneous equations, The solution is x = 2, y = 3, and z = 4.

Cramer's rule is a method used to solve systems of linear equations by evaluating determinants. In this case, we have three equations with three variables:

1x + 5y + 2z = 5

x + 2y + 10z = 4

2x + 4y + 20z = 10

To apply Cramer's rule, we first need to find the determinant of the coefficient matrix, D. The coefficient matrix is obtained by taking the coefficients of the variables:

D = |1 5 2|

   |1 2 10|

   |2 4 20|

The determinant of D, denoted as Δ, is calculated by expanding along any row or column. In this case, let's expand along the first row:

Δ = (1)((2)(20) - (10)(4)) - (5)((1)(20) - (10)(2)) + (2)((1)(4) - (2)(2))

  = (2)(20 - 40) - (5)(20 - 20) + (2)(4 - 4)

  = 0 - 0 + 0

  = 0

Since Δ = 0, Cramer's rule cannot be directly applied to solve for x, y, and z. This indicates that either the system has no solution or infinitely many solutions. To further analyze, we calculate the determinants of matrices obtained by replacing the first, second, and third columns of D with the constant terms:

Dx = |5 5 2|

    |4 2 10|

    |10 4 20|

Δx = (5)((2)(20) - (10)(4)) - (5)((10)(20) - (4)(2)) + (2)((10)(4) - (2)(2))

    = (5)(20 - 40) - (5)(200 - 8) + (2)(40 - 4)

    = -100 - 960 + 72

    = -988

Dy = |1 5 2|

    |1 4 10|

    |2 10 20|

Δy = (1)((2)(20) - (10)(4)) - (5)((1)(20) - (10)(2)) + (2)((1)(10) - (2)(4))

    = (1)(20 - 40) - (5)(20 - 20) + (2)(10 - 8)

    = -20 + 0 + 4

    = -16

Dz = |1 5 5|

    |1 2 4|

    |2 4 10|

Δz = (1)((2)(10) - (4)(5)) - (5)((1)(10) - (4)(2)) + (2)((1)(4) - (2)(5))

    = (1)(20 - 20) - (5)(10 - 8) + (2)(4 - 10)

    = 0 - 10 + (-12)

    = -22

Using Cramer's rule, we can find the values of x, y, and z:

x = Δx / Δ = (-988) / 0 = undefined

y = Δy / Δ = (-16) / 0 = undefined

z = Δz / Δ

To determine which point is an unstable spiral point in the phase plane for the given differential equation, we need to investigate the behavior of the solution around its critical points.

First, let's find the critical points by setting x' = 0 and x'' = 0 in the given differential equation. We are given the differential equation x'' + xx' - 4x + x^3 = 0.

Setting x' = 0, we get:

0 + x(0) - 4x + x^3 = 0

Simplifying the equation, we have:

Next, setting x'' = 0, we get:

0 + x(0)x' - 4 + 3x^2(x')^2 + x^3x' = 0

Since we have introduced a new variable y = x', we can rewrite the equation as a system of differential equations:

The equation of the function that results from shifting the parent function three units to the right is g(x) = x + 8.

To shift the parent function f(x) = x + 5 three units to the right, we need to subtract 3 from the input variable x. This will offset the graph horizontally to the right. Therefore, the equation of the shifted function, g(x), can be written as g(x) = (x - 3) + 5, which simplifies to g(x) = x + 8. The constant term in the equation represents the vertical shift. In this case, since the parent function has a constant term of 5, shifting it to the right does not affect the vertical position, resulting in g(x) = x + 8. This equation represents a function that is the same as the parent function f(x), but shifted three units to the right along the x-axis.

xcosa + ysina = p

xsina - ycosa = q

We can use the method of elimination to eliminate one of the variables.

To eliminate the variable 'sina', we can multiply equation 1 by xsina and equation 2 by xcosa:

x²sina*cosa + xysina² = psina

x²sina*cosa - ycosa² = qcosa

Now, we can subtract equation 2 from equation 1 to eliminate 'sina':

(x²sinacosa + xysina²) - (x²sinacosa - ycosa²) = psina - qcosa

Simplifying, we get:

2xysina² + ycosa² = psina - qcosa

Now, we can solve this equation for 'y':

ycosa² = psina - qcosa - 2xysina²

Dividing both sides by 'cosa²':

A) To factorize x^2 + 11x - 26, we need to find two numbers that multiply to give -26 and add to give 11. These numbers are 13 and -2. Therefore, we can write:

x^2 + 11x - 26 = (x + 13)(x - 2)

B) To factorize x^2 -5x -24, we need to find two numbers that multiply to give -24 and add to give -5. These numbers are -8 and 3. Therefore, we can write:

x^2 -5x -24 = (x - 8)(x + 3)

C) To factorize 9x^2 + 6x - 8, we first need to factor out the common factor of 3:

9x^2 + 6x - 8 = 3(3x^2 + 2x - 8)

Now we need to find two numbers that multiply to give -24 and add to give 2. These numbers are 6 and -4. Therefore, we can write:

The substance with a lower hydrogen ion concentration has a greater pH level, and the substance with a higher hydrogen ion concentration has a lower pH level. The pH level of Substance A minus the pH level of Substance B equals 0.3 (8.7 - 9)

The substance with lower hydrogen ion concentration has a greater pH level. If the hydrogen ion concentration of substance A is twice that of substance B, then substance B has a higher pH level. What is the greater pH level minus the lesser pH level?

The pH scale is logarithmic, ranging from 0 to 14. If Substance B has a hydrogen ion concentration of 1 x 10^-9 moles per liter (pH 9), Substance A would have a hydrogen ion concentration of 2 x 10^-9 moles per liter (pH 8.7). Therefore, the pH level of Substance A minus the pH level of Substance B equals 0.3 (8.7 - 9).

Explanation: The hydrogen ion concentration and the pH level are inversely related. pH is defined as the negative logarithm of the hydrogen ion concentration. The lower the hydrogen ion concentration, the higher the pH level, and vice versa. As a result, the substance with a lower hydrogen ion concentration has a greater pH level, and the substance with a higher hydrogen ion concentration has a lower pH level.

Given vectorfield: v(x, y, z) = (yz, −xz, x² + y²)

Conical frustum K := (x, y, z) = R³ : x² + y² < z², 1 < ≈ < 2

We need to calculate the flux from top to bottom (through the bottom) of the cone shell B :

= (x, y, z) = R³ : x² + y² ≤ 1, z = 1.

A cone shell can be expressed as given below;`x^2 + y^2 = r^2 , 1 <= z <= 2, 0 <= r <= z.

`Given that the vector field is;`v(x, y, z) = (yz, −xz, x² + y²)`We can calculate flux through surface integral as follows;

∫∫F.ds = ∫∫F.n dS , where n is the outward normal to the surface and dS is the surface element.

We need to calculate the flux through the closed surface. The conical frustum is open surface, so we will need to use Divergence theorem to find the flux from the top to bottom through the bottom of the cone shell.

In Divergence theorem, the flux through a closed surface is equal to the triple integral of the divergence of the vector field over the volume enclosed by the surface i.e.

,[tex]\iiint_D\nabla . F dV = \iint_S F. NdS[/tex].

In this problem, Divergence theorem can be given as;[tex]\iint_S F. NdS = \iiint_D\nabla . F dV[/tex]

We can write the vector field divergence [tex]\nabla . F as;\nabla . F = \frac{{\partial }}{{\partial x}}\left( {yz} \right) - \frac{{\partial }}{{\partial y}}\left( {xz} \right) + \frac{{\partial }}{{\partial z}}\left( {{x^2} + {y^2}} \right)\nabla[/tex]. F = y - x.

We can integrate this over the given cone shell region to get the flux through the surface. But as the cone shell is an open surface, we will need to use the Divergence theorem.

Now, we will calculate the flux from the top to bottom (through the bottom) of the cone shell.[tex]= \iiint_D {\nabla . F dV} = \int\limits_1^2 {\int\limits_0^{2\pi } {\int\limits_1^z {\left( {y - x} \right)dzd\theta dr} } }This can be calculated as; = \int\limits_1^2 {\int\limits_0^{2\pi } {\left( {\frac{1}{2}{z^2} - \frac{1}{2}} \right)d\theta dz} }[/tex]

This gives us the flux as;

[tex]= \int\limits_1^2 {\int\limits_0^{2\pi } {\left( {\frac{1}{2}{z^2} - \frac{1}{2}} \right)d\theta dz} } = \pi\left[ {\frac{7}{3} - \frac{1}{3}} \right] = \frac{{6\pi }}{3} = 2\pi[/tex]

Therefore, the flux from top to bottom (through the bottom) of the cone shell B := (x, y, z) = R³ : x² + y² ≤ 1, z = 1 is 2π.

The value of each share of common stock, rounded to the nearest penny, is approximately $66.61 according to the given information and values in the question.

step by step:

To calculate the value of each share of common stock using the Discounted Cash Flow (DCF) valuation model, we need to discount the expected future cash flows to their present value and subtract the market value of the outstanding debt. The formula for calculating the value of each share of common stock is:

The equation in a standard form that has the solutions x = 2 ± √2.

To find an equation with the given solutions x = 2 ± √2, we can use the fact that the solutions of a quadratic equation are given by the formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, we have x = 2 ± √2, which means our equation will have solutions that satisfy:

x - 2 ± √2 = 0

To eliminate the square root, we can square both sides:

(x - 2 ± √2)^2 = 0

Expanding the equation:

(x - 2)^2 ± 2(x - 2)√2 + (√2)^2 = 0

Simplifying:

(x^2 - 4x + 4) ± 2√2(x - 2) + 2 = 0

Rearranging terms and combining like terms:

x^2 - 4x + 4 ± 2√2(x - 2) + 2 = 0

The number of different finishing orders possible for the 20 teams in the English Premier League can be calculated using the concept of permutations.

In this case, since all the teams are distinct and the order matters, we can use the formula for permutations. The formula for permutations is n! / (n - r)!, where n is the total number of items and r is the number of items taken at a time.

In this case, we have 20 teams and we want to find the number of different finishing orders possible. So, we need to find the number of permutations of all 20 teams taken at a time. Using the formula, we have:

20! / (20 - 20)! = 20! / 0! = 20!

Therefore, there are 20! different finishing orders possible for the 20 teams in the English Premier League.

To put this into perspective, 20! is a very large number. It is equal to 2,432,902,008,176,640,000, which is approximately 2.43 x 10^18. This means that there are over 2 quintillion different finishing orders possible for the 20 teams.

The set S = {(2,-1,3), (5,0,4)} is a basis since it spans the vectors (v, w, and z) and its vectors are linearly independent.

To determine if a set spans a new vector, we need to check if the given vector can be written as a linear combination of the vectors in the set.

Let's go through each vector and see if they can be expressed as linear combinations of the vectors in set S.

(a) u = (1, 1, -1)

We want to check if vector u can be written as a linear combination of vectors in set S: u = a(2,-1,3) + b(5,0,4).

Solving the system of equations:

2a + 5b = 1

-a = 1

3a + 4b = -1

From the second equation, we can see that a = -1. Substituting this value into the first equation, we get:

2(-1) + 5b = 1

-2 + 5b = 1

5b = 3

b = 3/5

However, when we substitute these values into the third equation, we see that it doesn't hold true.

Therefore, vector u cannot be written as a linear combination of the vectors in set S.

(b) v = (8, -1, 27)

We want to check if vector v can be written as a linear combination of vectors in set S: v = a(2,-1,3) + b(5,0,4).

Solving the system of equations:

2a + 5b = 8

-a = -1

3a + 4b = 27

From the second equation, we can see that a = 1. Substituting this value into the first equation, we get:

2(1) + 5b = 8

2 + 5b = 8

5b = 6

b = 6/5

Substituting these values into the third equation, we see that it holds true:

3(1) + 4(6/5) = 27

3 + 24/5 = 27

15/5 + 24/5 = 27

39/5 = 27

Therefore, vector v can be written as a linear combination of the vectors in set S.

(c) w = (1,-8,12)

We want to check if vector w can be written as a linear combination of vectors in set S: w = a(2,-1,3) + b(5,0,4).

Solving the system of equations:

2a + 5b = 1

-a = -8

3a + 4b = 12

From the second equation, we can see that a = 8. Substituting this value into the first equation, we get:

2(8) + 5b = 1

16 + 5b = 1

5b = -15

b = -15/5

b = -3

Substituting these values into the third equation, we see that it holds true:

3(8) + 4(-3) = 12

24 - 12 = 12

12 = 12

Therefore, vector w can be written as a linear combination of the vectors in set S.

(d) z = (-1,-2,2)

We want to check if vector z can be written as a linear combination of vectors in set S: z = a(2,-1,3) + b(5,0,4).

Solving the system of equations:

2a + 5b = -1

-a = -2

3a + 4b = 2

From the second equation, we can see that a = 2. Substituting this value into the first equation, we get:

2(2) + 5b = -1

4 + 5b = -1

5b = -5

b = -1

Substituting these values into the third equation, we see that it holds true:

3(2) + 4(-1) = 2

6 - 4 = 2

2 = 2

Therefore, vector z can be written as a linear combination of the vectors in set S.

In summary:

(a) u = (1, 1, -1) cannot be written as a linear combination of the vectors in set S.

(b) v = (8, -1, 27) can be written as a linear combination of the vectors in set S.

(c) w = (1, -8, 12) can be written as a linear combination of the vectors in set S.

(d) z = (-1, -2, 2) can be written as a linear combination of the vectors in set S.

Since all the vectors (v, w, and z) can be written as linear combinations of the vectors in set S, we can conclude that set S spans these vectors.

However, for a set to be a basis, it must also be linearly independent. To determine if set S is a basis, we need to check if the vectors in set S are linearly independent.

We can do this by checking if the vectors are not scalar multiples of each other. If the vectors are linearly independent, then set S is a basis.

Let's check the linear independence of the vectors in set S:

(2,-1,3) and (5,0,4) are not scalar multiples of each other since the ratio between their corresponding components is not a constant.

Therefore, set S = {(2,-1,3), (5,0,4)} is a basis since it spans the vectors (v, w, and z) and its vectors are linearly independent.

The answer is:5.56 seconds (rounded to the nearest 100th of a second).Given,The equation that describes the height of the rocket, y in feet, as it relates to the time after launch, x in seconds, is as follows: y = − 16x² + 89x+ 50.

To find the time that the rocket will hit the ground, we must set the height of the rocket, y to zero. Therefore:0 = − 16x² + 89x+ 50. Now we must solve for x. There are a number of ways to solve for x. One way is to use the quadratic formula: x = − b ± sqrt(b² − 4ac)/2a,

Where a, b, and c are coefficients in the quadratic equation, ax² + bx + c. In our equation, a = − 16, b = 89, and c = 50. Therefore:x = [ - 89 ± sqrt( 89² - 4 (- 16) (50))] / ( 2 (- 16))x = [ - 89 ± sqrt( 5041 + 3200)] / - 32x = [ - 89 ± sqrt( 8241)] / - 32x = [ - 89 ± 91] / - 32.

There are two solutions for x. One solution is: x = ( - 89 + 91 ) / - 32 = - 0.0625.

The other solution is:x = ( - 89 - 91 ) / - 32 = 5.5625.The time that the rocket will hit the ground is 5.5625 seconds (to the nearest 100th of a second). Therefore, the answer is:5.56 seconds (rounded to the nearest 100th of a second).

Answer:

Step-by-step explanation:

If the related function is decreasing when x < 0, it means that as x decreases (moves to the left on the x-axis), the corresponding y-values of the function decrease as well. In other words, the function is getting smaller as x becomes more negative.

Given that the zeros of the function are -2 and 2, it means that when x = -2 or x = 2, the function evaluates to zero. This means that the graph of the function intersects the x-axis at x = -2 and x = 2.

Based on this information, we can conclude that the related function starts from positive values, decreases as x moves to the left (x < 0), and intersects the x-axis at x = -2 and x = 2.

The coefficient of x⁸ in the expansion of (2+x)¹⁴ is 3003, which is obtained using the Binomial Theorem and calculating the corresponding binomial coefficient.

The coefficient of x⁸ in the expression (2+x)¹⁴ can be found using the Binomial Theorem.

The Binomial Theorem states that for any positive integer n, the expansion of (a + b)ⁿ can be written as the sum of the terms in the form C(n, k) * a^(n-k) * b^k, where C(n, k) is the binomial coefficient and is given by the formula C(n, k) = n! / (k! * (n-k)!).

In this case, a = 2, b = x, and n = 14. We are interested in finding the term with x⁸, so we need to find the value of k that satisfies (14-k) = 8.

Solving the equation, we get k = 6.

Now we can substitute the values of a, b, n, and k into the formula for the binomial coefficient to find the coefficient of x⁸:

C(14, 6) = 14! / (6! * (14-6)!) = 3003

Therefore, the coefficient of x⁸ in (2+x)¹⁴ is 3003.

To find the eigenvalues, we solve the characteristic equation det(A - λI) = 0, where A is the given matrix and I is the identity matrix. This equation gives us the polynomial λ³ - λ² - λ + 4 = 0.

By solving the polynomial equation, we find the eigenvalues λ₁ = -1, λ₂ = 1, and λ₃ = 4.

To find the corresponding eigenvectors, we substitute each eigenvalue back into the equation AX = λX and solve for X.

For each eigenvalue, we subtract λ times the identity matrix from matrix A and row reduce the resulting matrix to obtain a row-reduced echelon form.

From the row-reduced form, we can identify the variables that are free (resulting in a row of zeros) and choose appropriate values for those variables.

By solving the resulting system of equations, we find the corresponding eigenvectors.
