Is (4,4) a solution to 4x + 2y <-8

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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
