Step-by-step explanation:
One inequality could be x > 3. So when x = 4 this is true because 4 is greater than 3.
20+4x=76 subtract 20 from both sides
4x=56 divide both sides by 4
x=14
So he was driving at 55+14=69 mph
X intercept 1.375
Y intercept -2.2
F(x) = 3x+1
G(x) = X^2 - 6
F(G(x)) = F(X^2 - 6) = 3(X^2 - 6) + 1 = 3X^2 - 18 + 1 = 3X^2 -17
F(G(x)) = 3X^2 - 17
