If the point (a, b) was translated 7 units to the left and 5 units down and then reflected across the x-axis, its new coordinates, in terms of a and b would be (1) (-a+7,b+5) (3) (a-7,-b+5) (2) (a+7,b+5) (4) (-a-7,-b-5)

step-by-step explanation:

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).
