What are the solutions to the system of
equations?
(-23,400, 3,400) and (-1,170, 170)
(-1,170, -23,400) and (170, 3,400)
(274, 726) and (5,480, 14,520)
(274, 5,480) and (726, 14,520)
DONE
y=-0.01(x - 500)2 + 4.489
y = 20x
You used substitution to obtain the equation
0 = -0.01x2-10x+1,989 from the system
