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
Answer
1/2
Step-by-step explanation:
A=(1/2)(h)(B+b)
(6)=(1/2)(h)((2)+(1))
12=h(3)
h=4
Answer: h=4
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
