We factor the equation to get:
-(x-25)^2+361
In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.
B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.
96/4. You should get the answer by dividing 96 by 4.
<h3>Given ↓</h3>
- Two points that a line goes through
<h3>To Find ↓</h3>
<h3>Calculations ↓</h3>
When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.
This is the formula :

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates
Plug in the values :


Which simplifies to
, or 1

You add the two numbers together and get $98.81
-19 + (-12) = 7
Remove Parentheses
( -a ) = -a
= 19 - 12
Subtract The Numbers
19-12 = 7
