Given the function f(x) = 5/2x-7, what is the corresponding value when x = -6?

When you substitute x=-6, you get 5/-19

its 5/-19 when you substitute x=-6

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
