Given the equation of the circle find the center and the radius:
(x - 3)2 + (y + 1)2 = 49

(3, -1), 7

Step-by-step explanation:

To find the center of this circle:  compare the given equation

(x - 3)^2 + (y + 1)^2 = 7^2   to the standard equation of a circle with center at (h, k):

(x - h)^2 + (y -k)^2 = r^2

From this comparison we see that the center is at

h = 3 and k = -1, and also that r must be 7:    (3, -1), 7

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

it is not that hard all u have to do is plot the graph
