Write an expression and then evaluate when x = -6. nine subtracted from the quotient of twice a number, x, and three. evaluate when x = -6:

(2x/3) - 9 is the expression you want

When x = -6  we have

(-12/3) - 9 =  -13   answer

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
