The center of the circle (x + 9)² + (y − 6)² = 10² is at (-9, 6) and the radius of the circle is 10 units.
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The equation of the circle is given as
(x + 9)² + (y − 6)² = 10²
Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.

With the information provided, we can begin with the equation:
y=35x + b
With x = number of hours, y = total cost, b = fixed amount that is charged for residential work
We know that after 6 hours, $270 was charged:
$270 = $35(6) + b
Solve for b:
b = $270 - $210 = $60
The fixed amount that is charged for residential work is $60. So now we can rewrite the equation as:
y = 35x + 60
I believe the answer would be $63,600.
