Use the associative property to simplify the expression. 43 + 30 + 70
O A. 43+ (30 + 70) = 43 + 100 = 143
O B. 43 + 30 + 70 = 73 + 70 = 143
C. 43 + 70 + 30 = 113 + 30 = 143
O D. 43 + 10(3 + 7) = 43 + 10(10) = 143

No links plsss

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. : )
