Answer:

Step-by-step explanation:

The center is at (0, -6) so the equation is:

(x - 0)^2 + ( y + 6)^2 = r^2

x^2 + (y + 6)^2 = r^2

r^2 = 11

Answer is x^2 + (y + 6)^2 = 11.

Given:

$5|x-3|+3>7$

Aim:

We need to find the value of x.

Explanation:

Subtract 3 from both sides of the equation.

$5|x-3|+3-3>7-3$

$5|x-3|>4$

Divide both sides of the equation by 5.

$\frac{5}{5}|x-3|>\frac{4}{5}$

$|x-3|>\frac{4}{5}$

Square both sides.

$(x-3)^2>(\frac{4}{5})^2$

$(x-3)^2>\frac{16}{25}$

$x^2-6x+9>\frac{16}{25}$

multiply

$x^2-6x+9>\frac{16}{25}$

First, subtract the fee to the final bill amount.

124.50 - 60 = $64.50 (amount paid for the total visit hourly without fee)

Second, divide to find how many hours the plumber took to repair.

64.50 / 21.50 = <u>3 hours</u>
