Step-by-step explanation:
A circle is a figure where all of the points on its graph are equidistant from a single, central point. You can define a circle in a plane with the formula (x-h)^2+(y-k)^2=r^2, where h represents the x coordinate of the center, k represents the y coordinate, and r represents the radius.

Answer:
C
Step-by-step explanation:
Decreased price = 16.50 - 12 = $ 4.50
Percent of decrease =

= 27%
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
Step 3 is the frist incorrect step it should be: 2x-3=3 or 2x-3=-3
