The equation for the monthly charge has the following format
In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.
Base charge of $17.32 per month.
This means that
charge of 7.32 cents per kilowatt-hour
Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is
Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

Step-by-step explanation:
<h3>7) The lengths of the tangent from an external point to a circle are equal.</h3>2x - 1 = x + 10
2x = x + 10 + 1
2x = x + 11
2x -x = 11
8) Radius : XC
Chord: CB
Diameter : AB
Name of the circle: X {a circle is named by its center}
