The sum of three times a number and eight is 23. Find the number.

5

Step-by-step explanation:

23-8 = 15

15/3 = 5

5x3 = 15 +8 = 23

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
