Answer:
The required function is:

Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get

Hence,
The required function is:

Answer:
week 5 and 107 dollars
Step-by-step explanation:
We can write it down as:
5 = 2x - 3 / + 3 (both sides)
8 = 2x / : 2 (both sides)
x = 4
Bob has 4 CDs. Let's check it:
5 = 2 * 4 - 3
5 = 8 - 3
5 = 5
Correct.
Answer:
-1/2
Step-by-step explanation:
Answer:
201.06 square feet
Step-by-step explanation:
area of a circle is given by πr², where π = 3.1416
A = 3.1416 * 8²
A = 3.1416 * 64 = 201.0624 square feet
A = 201.06 square feet
