Identify the center and the radius of each.

x^+y^+26x-22y+281=0

Center (-13,11) , radius 3

Step-by-step explanation:

The given circle has equation

We compare this to the general equation.

where (-a,-b) is the center.

This implies that;

2a=26

2b=-22

b=-11

The center is therefore (-13,11)

The radius is given by

The radius is 3

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
