f(x) = 6-5x
y = 6-5x .... replace f(x) with y
x = 6-5y .... swap x and y; solve for y
x+5y = 6
5y = 6-x
y = (6-x)/5
... replace y with the inverse function notation

Answer: Choice D.</h3>
Answer:
5 miles: $10
8 miles: $16
20 miles: $40
Step-by-step explanation:
Since each mile costs $2 and that it asks you to figure out the price for 5 miles, 8 miles and 20 miles, you multiply 2 with the amount of miles travelled
36/12 = 3
so
24/(6x - 4) = 3
3(6x - 4) = 24
18x - 12 = 24
18x = 36
x = 2

Step-by-step explanation: 6 11 10 48
spent $504
hair dryers cost $8 each
6 floors with the same number of rooms on each floor.
Money spent / hair dry cost = number of hair dryers bought
number of hair dryers = number of floors = hair dryers per floor Plus any remainder
504 / 8 = 63 hair dryers
63 / 6 = 10.5 so 10 rooms per floor = 60 hairs dryers with 3 left over
The correct answer is letter B
