Y is inversely proportional to x.
When y = 7, x = 9
a) Work out an equation connecting y and x.

if you mean

then it's c. 8, -7/3

but if you mean

then it is

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°

your answer is 125y5
