Hurry will give brainliest a truck can be rented from company a for $90 a day plus $0.30 per mile. company b charges $70 a day plus $0.80 per mile to rent the same truck. find the number of miles in a day at which the rental cost for company a and company b are the same

The rental costs for the two companies are equal at x = 40 miles.

Step-by-step explanation:

The total cost function for Company A is Ca = $90 + ($0.30/mile)x, where x is the number of miles driven during the one day of rental.

The total cost function for Company B is Cb = $70 + ($0.80)x.

Setting these two formulas = to one another and solving for x, we get:

$90 + ($0.30/mile)x = $70 + ($0.80)x

First, subtract $70 from both sides, obtaining:

$20 + ($0.30/mile)x = ($0.80)x

Subtracting ($0.30/mile)x from both sides results in:

$20 = ($0.50/mile)x

Dividing both sides by ($0.50/mile) results in

x = ($20) / ($0.50/mile) = 40 miles

The rental costs for the two companies are equal at x = 40 miles.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
