Basically look for the intersection points of these two functions by setting them equal to each other.
-x^2 + 6x = 21/4 - x/4
-x^2 + (25/4)x - 21/4 = 0
x = 1 and x = 21/4
Plug these points back to any of the two original equations, you will get
(1,5) and (21/4, 63/16)
Answer: x = 14
Step-by-step explanation:
Combine like terms
95+15 = 110
X + 4x = 5x
Set up equation
110 + 5x = 180
Subtract
110-110 + 5x = 180-110 = 70
Divide
5/5x = 70/5 = 14
Answer
X = 14
A=124
B=0.7x+75
124<0.7x+75
49<0.7x
70<x
When you drive more than 70 miles, company A is cheaper
