Answer:
a) 300 + 80h = x
b) $780
Step-by-step explanation:
So, the original cost is $300, plus an additional $80 times the number of hours rented.
h will represent the number of hours rented
x will represent our total cost (use whatever variable your teacher expects :))
300 + 80h = x
This is our equation. Now, we want to find the cost for 6 hours. Substitute 6 in for h.
300 + 80(6) = x Solve for x.
300 + 480 = x
780 = x This means the total cost for 6 hours will be $780.
Hope this helps :)
NOTE: I noticed in part a, it referred to a "dunking booth". I solved this problem as if that was a typo and they were referring to the jumper.
The answer is 1. just subtract the fractions and boom. answer.
A and B
Reason and proof:
suppose we have the following function
f(x) = 2x + 1
the y intercept is 1 therefor it'll intersect the y axis at (0,1)
however if the function was to be
f(x) = 2x - 1
the y intercept is -1 that means it intersect the y axis at (0,-1)
The rate of change should be 2
