QS = 38

Step-by-step explanation:

First, we need to find the value of x.

Given that R is the midpoint of Q and S, that means QR = RS.

6x-11 = 2x+9

Solve.

x = 5.

To find QS, we need to solve the following equation:

6x-11 + 2x+9

Substitute 5 for x.

6(5)-11+2(5)+9

30-11+10+9

38

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

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).
