Substitute the value of y
6x-2(3x+12)=-12
6x-6x-24=-12
-24=-12
False
Final answer: No solution (the lines are parallel)
The answer is C. supplementary
At 900 miles, the cost for the two rentals will be same.
Step-by-step explanation:
Given,
A+ Auto rental: $175 plus $0.10 per mile
Let,
x be the number of miles.
y be the total distance.
y = 0.10x+175 Eqn 1
Zippy Auto rental: $220 plus $0.05 per mile
y = 0.05x+220 Eqn 2
When Eqn 1 = Eqn 2, the cost will be same
Therefore;

Dividing both sides by 0.05

At 900 miles, the cost for the two rentals will be same.

Subtract 4 from 12 and multiply by 6
Amount of money - cost = revenue
20x -(10+7x) = revenue
13x - 10 = p(x)
