Step-by-step explanation:
Hi, to answer this question we have to analyze the function given:
C(b) = 2.75b + 10
Where:
- Independent variable: b (number of books)
- Input = b
- Output = C = annual cost
- Dependent variable = C (depends on b, the independent variable)
So:
A. The number of books purchased is the independent variable. TRUE
B. The input is the yearly cost. (FALSE, the input is the number of books )
C. The total yearly cost depends on the number of books purchased. TRUE
D. The number of books purchased is determined by the yearly cost. FALSE , the yearly cost is determined by the number
of books.
E. The output is the yearly cost.TRUE

Now it's xy=k+3
To get x we divide both sides by y
So x=(k+3)/y
