y = 1x + 5
Step-by-step explanation:
Because you pay $5 for the cup once, and to refill it, you have to pay $1 as how many times as you want.
Explanation:
The function is given below as

The set of domains is given below as

Step 1:
Put x=-1

Step 2:
Put x=0

Step 3:
Put x=1

Step 4:
Put x=2

Hence,
The range of g(x) using set notation will be

Hence,
The graph of g(x) is given below as
Answer:
a) the number of miles in 1 kilometer
Step-by-step explanation:
The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.
So to make the conversion<u> it is enough to know how many miles are in one kilometer.</u>
For example, lets convert 10miles/hour to kilometers/hour.
there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:

Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.
