X+y=-1 and x=y+19 solve for x

hi! i think the answer is 1/2 : )

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).

he answer is x=1x3 because x=1 to x=3

cool stunts are flippin i think

sitting on a chair

and using stick feet
