Which equation results from isolating a radical term and squaring both sides of the equation for the equation { x + 8 + 8x=8?
O x+8 =B4-%
O X4 B=B4+%
O x+Pm B4+%-16 5x
0 X + B = EA + x + 18

d. vertex

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

answer:

your answer is: c. 196 7/8 in^3.
