Distributive property and combining like terms i need

First you need to identify and group like terms.

You should rewrite d and 1d and group the coefficients together and you will have (-5 + 1) d + (-8 - 9)

Then combine - 5 + 1 to get - 4 so then you would have -4d + (-8 - 9)

Combine - 8 + -9 to get -17 after all you will end up with -4d - 17

-4d - 17

42

step-by-step explanation:

256/6=42

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. : )
