On a coordinate plane, 2 lines intersect around (3.8, negative 1.5). Given the graph of a system of equations, which statements are true about the solution? Check all that apply. The x-value is an integer. The x-value is between 3 and 4. The y-value is between –2 and –1. The x-value is positive. The x- and y-values have the same sign.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

5y

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).
