If p(4) = -16, p(-6) = 0, and p(5) doesnt equal p(-6), which statement is true A. (X+4) is a factor of p
B. (X-5) is a factor of p
C. (X+6) is a factor of p
D. (X+16) is a factor of p

each side has a different length.  

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

36
