For 6 hours charges $330
for 9 hours charges x
---------------------------------
x = 9*330/6 = 495 so choice C. is right
The formula of a slope:

We have the points A(-7, a) and B(c, d).
Substitute:

Exception: c ≠ -7.
A= -5 is the correct answer
Answer:
f(x) = 3x-1
g(x) = x+2
Find (f-g)(x), this means we need to subtract g from x.
(3x-1) - (x+2)
Subtract the like terms:
3x -x = 2x
-1 -2 = -3
Combine them to get 2x-3
The answer is B.
Brainliest would be much appreciated!
5/6 x 360 = 300
divide 360 by 6 = 60, then multiply 60 by 5 and you get 300.00
