Answer:
4). (x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
x^2 + y^2 + 4x - 2y - 20 = 0
x^2 + 4x + y^2 - 2y = 20
Completing the square on the x and y terms:
(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20
(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1
(x + 2)^2 + (y - 1)^2 = 25.
13. 8d - 10 = 4(2d - 6)
8d - 10 = 8d - 12
8d - 8d = -12 + 10
0 = -2......incorrect....NO SOLUTIONS
14. 3.50c > = 500
c > = 500/3.50
c > = 142.857....she can sell (minimum) of 143
15. 14c - 10 = 20
14c = 20 + 10
14c = 30
c = 30/14 reduces to 15/7 (or 2 1/7)
16. c = 1.50g + 3
