After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? Check all that apply.
A. -X^2 + 4x + 7 = 2x^2 - 9
B. -3x^2 +9x + 3x^2 = 14 + x - 1
C. 5x + 4 = 3x^2 - 2
D. x^2 + y^2 + x =0

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=

−9

2

x+10

7
