Every hour mph increases by 6
Supplementary because the add to 180°
An exterior angle equals the sum of the remote interior angles
.
So
x + 60 = 95
x = 95 - 60
x = 35
Answer
B. 35
Y = 5 - 4x
5 - 4x = x^2 - 2x - 19
0 = x^2 + 2x -24
0 = (x + 6)(x - 4)
Therefore x = -6 (Given) or 4
x = 4, y = -9
(4,-9) is the other solution
