Please help! I’ll give points if it’s correct! Simplify each expression

30. (3/8)^2

32. (3x/y)^4

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

i wish i could you, i have no idea how to answer this

step-by-step explanation:

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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).
