Answer:
(x-2)^2 +(y+3)^2 = 16
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 +(y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-2)^2 +(y- -3)^2 = 4^2
(x-2)^2 +(y+3)^2 = 16
<span>To find: Cost of backcover.
Solution:
Let the cost of backcover be x.
Then,
56 = 2x - 24
56+24 = 2x
80 = 2x
