Write x^2 - 6x + 7 = 0 in the form (x - a)^2 = b, where a and b are integers. (x - 4)^2= 3
(x - 3)^2 = 2
(x - 2)^2 = 1
(x - 1)^2 = 4

the image of (6, 9) under a dilation is (4, 6). the scale factor is

answer: options?

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
