Subtract 2x − 4 from x + 8. What's your answer? Question 8 options:

x + 12

−x + 4

x − 12

−x + 12

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3

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).

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
