Area of the large semicircle





Area of the small semicircle





Area of the figure


We can use substitution or elimination
Let’s use substitution
Make slope intercept equation for the first equation
Y = -x + 5
Now plug in the y value for the second equation
-5x - 4(-x + 5) = -18
-5x + 4x - 20 = -18
-1x = 2, x = -2
There is one solution
The equation represented by the model is <span>x</span>²<span> – 2x – 3 = (x – 3)(x + 1) is your answer.</span>
