PLEAS HELP I WILL MARK BRAINLIEST IF ITS RIGHT !! A truck can be rented from Company A for ​$50 a day plus ​$0.40 per mile. Company B charges ​$30 a day plus ​$90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
At ​miles, the rental costs are the same from either company.

40

Step-by-step explanation:

y = 50 + .4 x 40

y = 30 + .9 x 40

y = 66 for both equations

Step-by-step explanation:

If in doubt, model the situations as a system of equations and then attempt to solve!

It'll let m be the number of miles in these equations.

Cost of A = 50 + 0.4m

Cost of B = 30 + 0.9m

Set these equations equal to each other to find what value of m makes them equal:

50 + 0.4m = 30 + 0.9m

Subtract 0.4m from both sides:

50 = 30 + 0.5m

Subtract 30 from both sides:

20 = 0.5m

Multiply both sides by 2:

40 = m

Therefore, the prices are equal at 40 miles.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
