Answer:
The required inequality is
.
Jhon can buy at most 5 books.
Step-by-step explanation:
Consider the provided information.
Part(A)
Let b represent the number of books John buys.
He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.

The required inequality is
.
Part(B)




Part(C): Jhon can buy at most 5 books.
Answer:
5(1/5^3) ≠ 5(5^3)
Step-by-step explanation:
5(1/5^3) = 5(5^3)
5/27 = 625
5(1/5^3) ≠ 5(5^3)
The sides aren't equal, so this equation is FALSE.
It is d Ik Bc Ik don’t ask why just know it’s d
Y=2
If you subtract 9-7 you get the answer 2 which makes y=2.
For this case we have the following function:

By definition, we have that the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero.
So:

Thus, the function is not defined at 
The domain is given by all real numbers except 2.
Answer:
The domain is given by all real numbers except 2.
