Which of these expressions is not equivalent to the others? (3 n - n) + 9
(3 n + 7) - 6 - 7 + 4
(3n-n) + (7 - 6 + 4)
2n+5

10 you would take 50/ .2

step-by-step explanation:

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. : )
