Answer:
The correct answer is (-5,-5)
Step-by-step explanation:
1. Both of the equations are in standard form, so first you set them equal to each other.
2. Solve for x as a normal algebraic equation.
3. Back substitute your answer for x into one of the original equations. (back substitution is just putting the x back into the equation and solving for y.)
4. Now you have your x and y coordinates, and the point of intersection of the two lines.

Answer:
x = 6, x = 44; The zeros represent the number of monthly memberships where no profit is made.
Step-by-step explanation:
f(x) = −x² + 50x − 264
−x² + 50x − 264 = 0
-x² + 44x + 6x - 264 = 0
-x(x - 44) + 6(x - 44) = 0
(x - 44)(-x + 6) = 0
x = 6, 44
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
