On a coordinate plane, the center of circle P is at the point (2,15). Point M is located on the circle at (7,3). Which equation describes circle P?

A. (x+2)^2+(y+15)^2=13
B. (x-2)^2+(y-15)^2=13
C. (x+2)^2+(y+15)^2=169
D. (x-2+)^2+(y-15)^2=169

Ibelieve the total for the tip could be $21.90

The answer is that the rate of change is $50 per 1 monthhope this ; )

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
