Which equation describes a line passing through (-3,1) that is parallel to y=4x+1?A) y= -0.25x + 0.25

B) y= 4x - 11

C) y= -0.25x + 1.75

D) y= 4x + 13

Answers

Answer:

D. y= 4x + 13

Step-by-step explanation:

the slope would have to be 4 to be parallel

so plug the points in

1=4(-3) + b

1= -12 +b

13 = b

Select all the equations that are equivalent to this equation.1/4 (8x + 56) = 20

1; 56 + 8x = 80
2; 14 = 20 – 8x
3; 2x + 14 = 5
4: 2x = 6
5: x = 3

Answers

The equations equivalent to 1/4 (8x + 56) = 20 are

1. 56 + 8x = 80

2.14 = 20 - 8x

4.2x = 6

5. x = 3

What is an equation?

An equation is a mathematical expression that shows the relationship between two variables.

Since we have the equation 1/4(8x + 56) = 20, and we want to find all the equations that are equivalent to it, we solve the equation.

So, we proceed as follows.

1/4(8x + 56) = 20

Expanding the brackets, we have

8x/4 + 56/4 = 20

2x + 14 = 20

Subtracting 14 from both sides, we have that

2x = 20 - 14

2x = 6

x = 6/2

x = 3

Also, in 1/4(8x + 56) = 20

Multiplying through by 4, we have that

8x + 56 = 80

2x + 14 = 20

Subtracting 2x from both sides, we have that

14 = 20 - 2x

So, the equations are

1. 56 + 8x = 80

2.14 = 20 - 8x

4.2x = 6

5. x = 3
