Answer:
C = 15 + 0.11y
Step-by-step explanation:
Let us assume that Hannah utilizes x kilowatt-hour of electricity per month.
The electricity company charges $ 0.11 per kilowatt-hour of electricity uses and plus a basic connection charge of $ 15.
Therefore, the linear function that models her monthly electricity bill (C) as a function of electricity usage (y) will be
C = 15 + 0.11y {Hence, C will be a linear function of y} (Answer)
Answer:
use formula
area of semicircle + area of trapezium
4b - 10 = 2 (2b - 5)
4b - 10 = 4b - 10
4b - 4b = -10 + 10
b = 0
Hence, b has only one answer so,
we can say that this equation has only one solution.
