To solve the equation -x - 3 = x2 – 2x-15, you
could graph of the following system.
y = -x - 3
y = x2 – 2x – 15
use the graph of this system to identify all
solutions of -x - 3 = x2 – 2x – 15.

-7

-3 & 4

Step-by-step explanation:

This was correct on EDG 2020

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
