Answer:
Total rental cost is:
y = Bx + M
where x is number of additional hours, y is total cost, M is fixed fee, and B are is amount that is charged per hour.
Step-by-step explanation:
Let amount of flat fee = M
let hourly rate = B
Total rental cost = ?
As given the store charges a flat fee plus an hourly rate:
⇒ y = Bx + M
where x is number of additional hours, y is total cost, M is fixed fee, and B are is amount that is charged per hour.

Answer:
t=r/(sq)
Step-by-step explanation:
r=sqt
=> r/(sq)=t
If you fit the vertex and the y-intercept into that form of the parabola, what you get is this:

and

and 16a=16. Solve that a to get that a = 1. Now you have your true parabola equation in vertex form, which is:

or just

Follow my work here to find the x-intercepts:

(x-4)(x-4)-1=y and

Simplifying by combining like terms gives you this parabola:

In order to find the x-intercepts, or the roots of the parabola as they are also known as, you have to set y equal to 0 (because the x-intercepts are found when y = 0, right?)

Factoring that gives you (x-5)(x-3)=0 and that x-5=0 and x-3=0. Solving each of those simple equations gives you x=5 and x=3 when y=0. So the roots, in the form you require them, are (5, 0) and (3, 0)
