Answer:
Linear equation
Step-by-step explanation:
f(x) = 2x + 15
Linear because constant increase
Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:
Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.
Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.
The red car can travel farther on 1 gallon of gas.
11 and -28
11x-28=-308
11+-28=-17
The answer is C. 5 1/2 hours. Hope this helped. :)
