Answer:
4 hours of rental
Step-by-step explanation:
y1 = 20 + 13.5x
y2 = 6 + 17x
20 + 13.5x = 6 + 17x
20 - 6 = 17x - 13.5x
14 = 3.5x
x = 4
Costs y1 and y2 are equal on renting for 4 hours
It is B because I had the question before in my school
Answer:
no
Step-by-step explanation:

That means that they cannot be a function.
(1) will write us of the following form

(2) [do not it need explanation]

(3) Left place variable "y" and right place, variable "x" like this

(4) Integrate both members

(5) Solve us the integrals

(6) Isolate variable "y"

C: any cosntant
