Factor the polynomial: -6x3 - 12x2 - 18x
O A. -6x(x2 + 2x – 18)
O B. -6x(-x2 - 2x - 3)
O C. 6x(x2 + 2x - 3)
O D. -6x(x2 + 2x+3)
TESTER

O D. -6x(x2 + 2x+3)

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

yes   because as the functions are graphed they eventually will intersect unless otherwise
