Answer:
(x-6)^2 + (y+8)^2 = 25
Step-by-step explanation:
The equation for 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
The diameter is 10 so the radius is 10/2 =5
the center is 6,-8
(x-6)^2 + (y- -8)^2 = 5^2
(x-6)^2 + (y+8)^2 = 5^2
(x-6)^2 + (y+8)^2 = 25
Answer:
Then y = 6
Step-by-step explanation:
y = -x + 7
x = 1
y = -1 + 7
= 6
Answer:
First blank is cos(h)cos(x)
Second blank is sin(x)
Step-by-step explanation:
Look up the identity and apply it here
Answer:
2x^2 + 3/2x -5
Step-by-step explanation:
f(x) = x/2 -2
g(x) = 2x^2 +x -3
f(x)+ g(x) = x/2 -2+ 2x^2 +x -3
Combine like terms
= 2x^2 + 3/2x -5
Answer:
Step-by-step explanation:
12/(x+2) = 4/(x-2)
Cross-multiply to get:
12x-24 = 4x+8
8x = 32
x = 4
