40 pts and brainliest. geometry proof.

in the diagram, xpy is a tangent to the left hand circle, and pcda and pefb are straight lines. ab is parallel to xpy. prove that ce is parallel to dy.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
