Mary did the following problem

57-6^2+(10+2)
57 - 6^2 +12
57-36+12
57-48
9
which of the following statements are true?

it is wrong because 6 2 is 12.
it is correct.
it is wrong because the subtraction should have been done before the addition.
it is wrong because 57 - 48 is 11

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. : )
