Select the correct answer. Which equation could be solved using this application of the quadratic formula?
-3 + 32 – 4(1)(24)
2(1)
r =
O A. 12 + 61 + 24 = 3.r
OB.
3.r2 + 3.1 + 24 =3
OC. r2 + 3.1
24 = 3
OD. 12 + 3r + 24 =3

c is the correct answer

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
