Step-by-step explanation:

y=3x+2;y=2x+2

Step: Solve y=3x+2 for y:

y=3x+2

Step: Substitute 3x+2 for y in y=2x+2:

y=2x+2

3x+2=2x+2

3x+2+−2x=2x+2+−2x(Add -2x to both sides)

x+2=2

x+2+−2=2+−2(Add -2 to both sides)

x=0

Step: Substitute 0 for x in y=3x+2:

y=3x+2

y=(3)(0)+2

y=2(Simplify both sides of the equation)

Answer:

x=0 and y=2

Ansel has to pay an interest of $167.4 per months for the the life of the loan to the Hampton County Bank.

The formula for the monthly installments are-

M = P(r/12)(1 + r)∧12t / (1 + r)∧12t - 1

Put the values;

Principal P =$10,000.

Rate of interest r = 6.35%

Time t = 6 years 72 months

M =  10,000(0.0635/12)(1 + 0.0635)∧72 / (1 + 0.0635)∧72 - 1

M = $167.4

Thus, Ansel has to pay an interest of $167.4 per month for the the life of the loan to Hampton County Bank.

  Ex: (0,5) and (3,-1)

2. subtract the y-coordinates: -1-5 = -6

   and the x- coordinates (IN THE SAME ORDER): 3-0 = 3

3. divide the difference in y (-6) by the difference in x (3): -6/3 = -2

For the inequality 4x ≤ 28 the solution that makes the inequality true will be x≤7.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that the inequality is 4x ≤ 28.

Now that the equation has been simplified, we obtain both sides of the inequality equation, divide by 4, and we obtain

x ≤ 7

As a result, x must be less than or equal to 7.

The requirement for x is satisfied by any numbers that are less than or equal to 7.

Thus, for the inequality 4x ≤ 28 the solution that makes the inequality true will be x≤7.

The value of the variable x in the equation xˣ²⁻²ˣ⁺¹ = 2x + 1 is  1 + √2

An equation is a mathematical statement that shows that two mathematical expressions are equal.

An equation combines two expressions connected by an equal sign. These two expressions on either side of the equals sign are called the “left-hand side” and “right-hand side” of the equation. We generally assume the right-hand side of an equation is zero.

Basically, an equation is a statement that equate or says two expressions are equal to one another.

The problem given may be assumed as an exponential equation

xˣ²⁻²ˣ⁺¹ = 2x + 1

Solving for x by isolating the variable;

Answer:

  x = 1 ±√2

Step-by-step explanation:

You want to solve the exponential equation ...

  x^(x² -2x +1) = 2x +1

without using a calculator.

There are no algebraic methods for solving such an equation.

We can solve quadratic equations, so we can guess that the exponent of x is 2:

  x² -2x +1 = 2

  x² -2x -1 = 0

Using 2 as an exponent, the given equation becomes ...

  x² = 2x +1 . . . . . . . exponent on the left is 2

  x² -2x -1 = 0

That is, the exponent being 2 is consistent with the requirements on x.

The solution to the quadratic can be found using the quadratic formula:

  x² -2x -1 = 0

  x = (-(-2) ±√((-2)² -4(1)(-1))/(2(1)) = (2±2√2)/2

  x = 1±√2

Either of these values will make the exponent of x be 2, so both are solutions to the equation. The negative solution is not found by the graphing calculator (attached).

(a) The probability that the first person selected is a pledge is; 10/35

(b) The probability that the first person selected is not a pledge is; 25/35

(c) The probability that the second person selected is a pledge if the first person selected was also a pledge is; 9/34

We are given;

Total number of members in the Sorority = 35

Number of full members = 25

Number of members that are pledges = 10

Formula for probability is;

Probability = Number of Favorable Outcomes / Total Number of Outcomes.

1) Probability that the first person selected is a pledge = number of pledges/total number of members = 10/35

2) Probability that the first person selected is not a pledge = 1 - (Probability that the first person selected is a pledge)

= 1 - 10/35 = 25/35

3)  If the first person selected was also a pledge, then for the second pledge, one pledge is out, so we have 9 pledges in 34 people.

The total distance traveled on the bicycle is 2500m

The total time the bike traveled is 19.4 minutes.

The average speed (in meters/min) of the bicyclist for this trip is 128.9 m/minutes.

Speed is the rate at which an object's location changes in a particular direction. The distance traveled on relation changes to a particular direction. The distance in relation to the time it took to travel the distance is the speed.

The total distance traveled on the bicycle will be:

= 800 + 500 + 1200

= 2500m

The total time the bike traveled will be:

= 1.4 + 16 + 2

= 19.4 minutes

Speed = Distance / Time

= 2500 / 19.4

= 128.9 meters per minute

Step-by-step explanation:

In order to figure this out, we need to know what 114 plus 3 is.

114 + 3 = 117

Now that we have 117, we know that this is equal to 1/3 of the book.

In order to find out the total pages in this book, we need to multiply 117 by 3.

117 × 3 = 351

Let the width of the rectangle be x.

Given that,

length ⇒ 4

width ⇒ x + 4 ( Because, the rectangle's width is 4 more than the length.)

Perimeter ⇒ 36cm

The formula to find the perimeter of rectangle is:

P = 2 ( l + w )

Now to find the value of x replace P, l & w with 36, 4 & (x + 4) with respectively.

P = 2 ( l + w )

36 = 2 ( 4 + x + 4 )

36 = 2 ( x + 8 )

Solve the brackets.

36 = 2x + 16

Substract 16 from both sides.

36 - 16 = 2x

20 = 2x

Divide both sides by 2.

10 = x

And now let us find the exact dimensions of the rectangle.

Length = 4 cm

Width = x + 4 = 10 + 4 = 14 cm

The number of miles travelled by the family in one week is 700 miles

From the question, we have the following parameters that can be used in our computation:

Charges per week = $160

Charges per mile = $0.25

Total charges = $335

The above parameters mean that

Total charges = Charges per week + Charges per mile x Number of miles

Substitute the known values in the above equation, so, we have the following representation

160 + 0.25 * Number of miles = 335

This gives

0.25 * Number of miles = 175

Multiply both sides by 4

Number of miles = 700

Hence, the number of miles is 700

Answer:

The pattern is a repeated triangle and circle.

So, the next shape would be a triangle and a circle.

Step-by-step explanation:

The circumference of a circle with one-third the curvature of a circle of radius 1 is 18.85 units

What is circumference ?

The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.

If a circle has a radius of 1,

the curvature is inversely proportional to this

So, the curvature= 1

A circle with a curvature of 1/3 :

radius=3

Thus, the circumference of the circle  =  2 *π * radius

                                                               =  2*π * 3

                                                               =  6π

The solutions to the system of equations formed by the linear equation 9 · x + 9 · y - 79 = 0 and the quadratic equation x² + 5 · x - y - 4 = 0 are (x₁, y₁) = (5 / 3, 64 / 9) and (x₂, y₂) = (- 23 / 3, 148 / 9).

Herein we find a system of equations formed by a linear equation and a quadratic equation. This system must be resolved by means of algebra properties. First, write the system of equations:

9 · x + 9 · y - 79 = 0

x² + 5 · x - y - 4 = 0

Second, clear the variable y in the first equation:

9 · x + 9 · y - 79 = 0

9 · y = 79 - 9 · x

y = 79 / 9 - x

Third, substitute y on the second equation:

x² + 5 · x - (79 / 9 - x) - 4 = 0

x² + 6 · x - 115 / 9 = 0

Fourth, use the quadratic equation to find the solutions of x:

x₁ = 5 / 3, x₂ = - 23 / 3

Fifth, calculate the solutions of y:

y₁ = 79 / 9 - x₁

y₁ = 64 / 9

y₂ = 79 / 9 - x₂

y₂ = 148 / 9

The solutions are (x₁, y₁) = (5 / 3, 64 / 9) and (x₂, y₂) = (- 23 / 3, 148 / 9).
