When x = -3 on the graph of y = 2|x| + 3 what will be the y-coordinate?

a. -3
b. 3
c. -9
d. 9

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°

ratio is 2 : 9

the answer is three

13.5 : 3
