Sandy is comparing the taxi fares of two companies. EZ-Go Cabs charges a fixed charge of $3.50, plus $2.50 per mile traveled.
Safe Journey Taxi Service charges $4 per mile.
Which inequality can be used to find x, the minimum number of miles Sandy must travel to
make the total cost with EZ-Go Cabs less than the total cost with Safe Journey Taxi Service?
A 3.50 +2.50x < 4x
B 3.50x + 2.50 < 4x
C 3.50 +2.50x > 4x
D 3.50 -2.50x < 4x

If an x intercept only touches the x axis it means it has a multiplicity of 2. if an intercept goes through the axis it has a multiplicity of 1 true false
