Quick answers
abdulla is writing a program for a video game. for one part of the game he uses the rule: (x, y)  (x + 5, - y) to move objects on the screen.
(a) what output does the rule give when the input is (5, 3)? show your work.
(b) what output does the rule give when the input is (-2, 7)? show your work.

Part a

Use (x + 5, -y) for the input.

(5, 3) becomes (5 + 5, -3) = (10, -3).

Part b

Use the same rule.

(-2, 7) becomes (-2 + 5, -7) = (3, -7).

Done.

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°

i agree because i see the other persons thinking is clear
