sorry, I typed ordered pair wrong, the ordered pair is (-8, 8)
8x ≥ 420 8x/8 ≥ 420/8 x ≥ 52.5 They would need to travel greater than or equal to 52.5 mpg to meet their expectations.
First you need to replace the x in the original equation with the given variable 48-7y 8(48-7y) + 3y = -40 384 -56y +3y=-40 -56y + 3y = -40 - 384 -53y = -424 -53y/-53=-424/-53 y=8 x=-8 Ordered pair (8,-8)
