Solve for x: 5|2x − 2| + 8 = 18. (5 points)

x = 2, x = −2

x = −2, x = 0

x = 2, x = 0

x = 0, x =

it is not that hard all u have to do is plot the graph

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).
