If line l is reflected over the x-axis, and point A’ on the reflected line corresponds to point A on the
original line, how are distances between the points and the x-axis related?

c. If line l is rotated 180° about the origin and point A on the original line is farther left than point B,
how are points A’ and B’ on the rotated line related?

d. If line l is translated down and point A’ on the reflected line corresponds to point A on the original
line, how are points A and A’ related?

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

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).
