What are some expressions that are equivalent to 3(7x–6).

All the expressions must be equal to 21x - 18 if that expression wants to be equal to 3(7x – 6).

Step-by-step explanation:

Let's simplify and find out!

Final

Therefore, all the expressions must be equal to 21x - 18 if that expression wants to be equal to 3(7x – 6).

Hoped this helped.

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. : )
