LJK~QRS. The perimeter of QRS is 23. The perimeter of LJK is 92. What is the value of x

45

step-by-step explanation:

i suppose it should be (y=2x-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).

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
