Answer:
To find the solutions to this system of equations, we need to set f(x) equal to each other and solve for x.
x² - 2x - 15 = -x - 9
Simplifying and solving for x, we get:
x² - x - 6 = 0
Factoring the left side, we get:
(x - 3)(x + 2) = 0
So, the solutions are x = 3 and x = -2.
To find the corresponding y values, we can plug these x values back into either of the original equations. Using f(x) = x² - 2x - 15, we get:
f(3) = 3² - 2(3) - 15 = -3
f(-2) = (-2)² - 2(-2) - 15 = -9
Therefore, the ordered pair solutions for the system of equations are (3, -3) and (-2, -9).
