sattari [20]

Answer:

(x + 8)^2 + (y + 13)^2 = 13^2

Step-by-step explanation:

Write out (x - h)^2 + (y - k)^2 = r^2.  Recognizing that the center is at

(h, k), with h = -8 and k = -13, and that the radius is 13, we get:

(x + 8)^2 + (y + 13)^2 = 13^2

How do I solve question 5?
Nezavi [6.7K]
A) x^2 + y^2 = 80
B) x * y = 12

What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0
X = 1.355 (found by trial and error)
Y = <span> <span> <span> 8.85608</span></span></span> (found by trial and error)
