Match the pairs of equivalent expressions. 8b-15, (-14 +3/2b)–(1+8/2b), 4b+13/2, (5 +2b+3/2)(–10+b)+(7b–5), -5/2b-11, (7/2b-3)-(8+6b), -15-5/2b (No links please)

d is correct

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
