Answer:

B) Only (-2, 9)

Step-by-step explanation:

To find out which of the given options is the solution to the linear equation, y = -2x + 5:

We can substitute the values of the given options to see whether they provide a true statement.

A) (2, -9):

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1 (False statement. Therefore, this option is not included as a solution).

B) Only (-2, 9):

9 = -2(-2) + 5

9 = 4 + 5

9 = 9 (<u>True statement</u>. Thus, (-2, 9) is a solution to the given linear equation).

We no longer have to test options C and D because we already tested (2, -9) and determined that it's not a solution.

Therefore, the correct answer is option B) Only (-2, 9).

The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. What was the original length of
aleksley [76]

The Original length of each side of square was 14.25 inches.

Step-by-step explanation:

Perimeter of a square is given by:

Perimeter = 4 * side

Let x be the original length of each side of square

So

decreasing 2 inch will mean

x-2

Perimeter of square after reducing 2 inches from each side

4(x-2) = 49\\4x-8 = 49\\4x = 49+8\\4x = 57\\\frac{4x}{4} = \frac{57}{4}\\x = 14.25

So,

The Original length of each side of square was 14.25 inches.

Keywords: Perimeter, square

____ [38]

Answer: D. (6, 9)

<u>Step-by-step explanation:</u>

Midpoint is the "average" of the x's and y's:

Given: (5, 13) and (7, 5)

Midpoint: (\dfrac{5+7}{2},\dfrac{13+5}{2})

             = (\dfrac{12}{2},\dfrac{18}{2})

              = (6, 9)

Carlos takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $ 98 per cre
Sholpan [36]

Answer:

x + y = 13

98x + 115y = z

Step-by-step explanation:

Let x represent the time spent taking class in Westside community college

Let y represent the time spent taking class in Pinewood community college

Let z represent the combined total amount paid for the class fees.

The total combined time for the two school is given as:

x + y = 13.

For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.

Westside: 98 * x = 98x

Pinewood: 115 * y = 115y

The combined total amount represented as z is given as:

z = 98x + 115y
