5.J= {(0, 0), (4, -2)} g= {(0,4), (-2, 0), (5, 0)}
Find each pair of functions find f g and g f if they exist

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

Match each statement with its corresponding value for the system below: y = -2(3)x and y = 9x - 2 1. the number of points of intersection. -2 2. the x-coordinate of the solution. 1 3. the y-coordinate of the solution. 0

How do i do this activity, is appreciated
