Answer:

[tex]6[/tex]

The answer is C:6

Answer:

(36,-30)

Step-by-step explanation:

y = -30

Solve for x

y = -x+6

-30 = -x+6

Subtract 6 from each side

-36 = -x

Multiply each side by -1

x = 36

Answer:

y < -3x + 2

Step-by-step explanation:

The shading is below the line meaning the inequality is less than. Moreover, the line is dashed meaning there is no 'equal to'.

Therefore, the inequality is y < -3x + 2.

Answer:

0.2805

Step-by-step explanation:

Given that p = 20% = 0.2, n = 300.

The mean (μ) = np = 0.2 * 300 = 60

The standard deviation (σ) = [tex]\sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93[/tex]

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma }[/tex]

For x = 57:

[tex]z=\frac{57-60}{6.93 } =-0.43[/tex]

For x = 62:

[tex]z=\frac{62-60}{6.93 } =0.29[/tex]

From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805

Step-by-step explanation:

Breakeven point is the point of balance where their is neither a loss or a profit. At the breakeven point, the revenue gotten from the sell of goods is equal to the cost of production of the goods, hence the profit is zero.

Given the profit function:

P=-2b² + 14b - 20

At breakeven P = 0, hence:

0 = -2b² + 14b - 20

-2b² + 14b - 20 = 0

-2b² + 10b + 4b - 20 = 0

-2b (b - 5) + 4(b - 5) = 0

(b - 5)(-2b + 4) = 0

b - 5 = 0; or -2b + 4 = 0

b = 5; or b = 2

Since b is in thousands, hence the company breaks even when the number of skateboards produced is either 2000 or 5000

Answer:

y = 20 degree

Step-by-step explanation:

angle EOA = 5y (being vertically opposite angles)

angle COE + angle EOA + angle AOD = 180 degree (being linear pair)

2y + 5y + 2y = 180 degree

9y = 180

y = 180/9

y = 20 degree

Answer:

y = 20

Step-by-step explanation:

Angles COE and DOF are vertical angles and are congruent.

m<COE = m<DOF = 2y

<BOA is a straight angle and measures 180 degrees.

m<BOF + m<DOF + m<DOA = 180

5y + 2y + 2y = 180

9y = 180

y = 20

Answer:

Vertex: [tex](x,y) = (4,4)[/tex], Axis of symmetry: [tex]x = 4[/tex], no x-Intercepts, y-Intercepts: [tex](x,y) = (0, 36)[/tex]. The graph is represented in the image attached below.

Step-by-step explanation:

The equation of the parabola in vertex form and whose axis of symmetry is vertical is described by this formula:

[tex]y - k = C\cdot (x-h)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]C[/tex] - Vertex constant.

[tex]h, k[/tex] - Coordinates of the vertex.

By direct comparison, we find the following information:

[tex]h = 4[/tex], [tex]k = 4[/tex], [tex]C = 2[/tex]

Vertex

The vertex is a point of the parabola so that [tex](x,y) = (h, k)[/tex].

If we know that [tex]h = 4[/tex] and [tex]k = 4[/tex], then the coordinates of the vertex are [tex](x,y) = (4,4)[/tex].

Axis of symmetry

The axis of symmetry is a line of the form [tex]x = h[/tex].

If we know that [tex]h = 4[/tex], then the axis of symmetry is [tex]x = 4[/tex].

To find the x and y intercepts, we need to transform the equation of the parabola into its standards, which is a second grade polynomial:

[tex]y - k = C\cdot (x-h)^{2}[/tex]

[tex]y - k = C\cdot (x^{2}-2\cdot h\cdot x +h^{2})[/tex]

[tex]y = C\cdot x^{2} -2\cdot C\cdot h \cdot x + (C\cdot h^{2}+k)[/tex]

If we know that [tex]h = 4[/tex], [tex]k = 4[/tex] and [tex]C = 2[/tex], then the equation of the parabola in standard form is:

[tex]y = 2\cdot x^{2}-16\cdot x + 36[/tex]

x-Intercepts

The x-intercepts of the polynomial (if exist) can be found by the Quadratic Formula:

[tex]x_{1,2} = \frac{16\pm \sqrt{(-16)^{2}-4\cdot 2\cdot (36)}}{4}[/tex]

[tex]x_{1,2} = 4 \pm \frac{\sqrt{-32}}{4}[/tex]

[tex]x_{1,2} = 4 \pm i \,\frac{4\sqrt{2}}{4}[/tex]

[tex]x_{1,2} = 4 \pm i\,\sqrt{2}[/tex]

As both roots are conjugated complex numbers, there are no x-intercepts.

y-Intercepts

The y-intercept (if exists) can be found by evaluating the polynomial at [tex]x = 0[/tex]:

[tex]y = 2\cdot 0^{2} - 16\cdot 0 + 36[/tex]

[tex]y = 36[/tex]

The y-intercept is [tex](x,y) = (0, 36)[/tex].

Lastly, we proceed to plot the function by using graphing tools.

Answer:

Part A)

[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]

Part B)

Flight X sold 15 tickets and Flight Y sold 105 tickets.

Part C)

Flight X made $1,350 and Flight Y made $26,250.

Step-by-step explanation:

Let the amount of tickets sold by Flight X be represented by x and the amount of tickets sold by Flight Y be represented by y.

Part A)

The airline sold 120 tickets in total. Hence:

[tex]x+y=120[/tex]

Each x ticket costs $90 and each y ticket costs 250. The total income was $27,600. Thus:

[tex]90x+250y=27600[/tex]

Our system of equations is:

[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]

Part B)

Solve the system of equations. We can use substitution. From the first equation, subtract y from both sides:

[tex]x=120-y[/tex]

In the second equation, we can divide everything by 10 and substitute in x:

[tex]9(120-y)+25y=2760[/tex]

Simplify:

[tex]16y+1080=2760[/tex]

So:

[tex]y=105\text{ tickets}[/tex]

Using the equation above:

[tex]x=120-(105)=15\text{ tickets}[/tex]

Flight X sold 15 tickets and Flight Y sold 105 tickets.

Part C)

Since each ticket of Flight X sold for $90 and Flight X sold 15 tickets, Flight X made $1,350.

Then it follows that Flight Y made $26,250.

Answer:

$467.8125

Step-by-step explanation:

Percentage increase = 25% × 374.25

New value = 374.25 + Percentage increase

New value =

374.25 + Percentage increase =

374.25 + (25% × 374.25) =

374.25 + 25% × 374.25 =

(1 + 25%) × 374.25 =

(100% + 25%) × 374.25 =

125% × 374.25 =

125 ÷ 100 × 374.25 =

125 × 374.25 ÷ 100 =

46,781.25 ÷ 100 =

467.8125 ≈

Answer:

The distance between the lines: 4x+3y-11 and 8x+6y=15 is​ [tex]\frac{7}{10}[/tex]

Step-by-step explanation:

You have two parallel and different lines. The form of the implicit equations is:

A*x + B*y + C= 0

A'*x + B'*y + C'=0

Since the two lines are parallel, the coefficients of their general equations must satisfy that the slopes are equal.

Therefore, the equations can be transformed so that the coefficients A and B are equal, multiplying or dividing one of them by a constant.

So, the distance between two lines can be expressed as follows:

[tex]d=\frac{|C-C'|}{\sqrt{A^{2} +B^{2} } }[/tex]

In this case, you have:

Then, you have:

Replacing in the definition of distance:

[tex]d=\frac{|-22-(-15)|}{\sqrt{8^{2} +6^{2} } }[/tex]

Solving:

[tex]d=\frac{|-7|}{\sqrt{8^{2} +6^{2} } }[/tex]

[tex]d=\frac{7}{\sqrt{8^{2} +6^{2} } }[/tex]

[tex]d=\frac{7}{\sqrt{64+36 } }[/tex]

[tex]d=\frac{7}{\sqrt{100 } }[/tex]

[tex]d=\frac{7}{10}[/tex]

The distance between the lines: 4x+3y-11 and 8x+6y=15 is​ [tex]\frac{7}{10}[/tex]

✔ b + 0.75 = 1.89  

✔ subtract 0.75  

✔ b = $1.14

the person above me doesn't make since so here the answers

Benjamin presently have $1.14.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Benjamin needs $0.75 more cents to buy a granola bar that costs $1.89.

let Benjamin have the amount $b.

So, the Expression to represent the situation is:

b + 0.75 = 1.89  

Now, subtract 0.75 from both side

b + 0.75 - 0.75 = 1.89 - 0.75

b = 1.14

Answer:

a = 5

Step-by-step explanation:

According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder

In this case, the remainder would be zero

So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0

So we have this as;

x + 2 = 0

x = -2

-2^3 -2(-2)^2 -2(a) + 6 = 0

-8-8-2a + 6 = 0

-16 + 2a + 6 = 0

2a -10 = 0

2a = 10

a = 10/2

a = 5
