How do you solve y=2.5x+5

Answers

if you are solving for x.
y=2.5x+5
you subtract 5 from both sides.
-5=2.5x
then divide both sides with 2.5
-5/2.5 2.5/2.5
the 2.5s will cancel each other out.

B
Q(−2,−1),R(−3,−4),S(−5,−3),T(−4,0)

C
Q(1,2),R(4,3),S(3,5),T(0,4)

D
Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Answers

Answer:

The correct answer is:

D)   Q(2,1)  R(3,-4) S(5,-3) T(4,0)

Step-by-step explanation:

When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.

Then the new coordinates of the parallelogram are:

Q(2,-1)  R(3,-4) S(5,-3) T(-4,0)

The product of 8 and the sum of 4 and a number is 112. What is the number?Which equation could be used to solve for the number?
8 + 4n = 112
8 x 4 + n = 112
8(4 + n) = 112

Answers

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation that is used to solve the number for the statement "the product of 8 and the sum of 4 and a number is 112" is

8(4 + n) = 112.

The number n is 10.

Option C is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

3x + 4 = 5 is an equation

3x + 9 is an equation.

We have,

The product of 8 and the sum of 4 and a number is 112.

Let the number be n.

We can write as:

8 x (4 + n) = 112 _____(1)

8 x 4 + 8 x n = 112

32 + 8n = 112

Subtract 32 on both sides.

8n = 112 - 32

8n = 80

Divide both sides by 8.

n = 10

The number is 10.

We can cross-check

8 x (4 + 10 ) = 112

8 x 14 = 112

112 = 112

Proved.

Thus,

The equation that is used to solve the number for the statement "the product of 8 and the sum of 4 and a number is 112" is

8(4 + n) = 112.

The number n is 10.
