Answer:
   
Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
   (x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
   (x -2)^2 +(y -(-1))^2 = 4^2
   (x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A

Answer:
-21
Step-by-step explanation:
3t-7=5t
-7=5t-3t
-7=2t
t= -7/2
6t=?
6(-7/2)= -21
