Answer:
A.
Step-by-step explanation:
The center is at (0, -6) so the equation is:
(x - 0)^2 + ( y + 6)^2 = r^2
x^2 + (y + 6)^2 = r^2
r^2 = 11
Answer is x^2 + (y + 6)^2 = 11.
Answer:
There are no solutions.
Step-by-step explanation:
4x+5=6x+18-20-2x (Distributive Property)
4x+2x-6x=18-20+5 (Combine Like Terms)
0=3 (Simplify)
That doesn't make any sense, so there are no solutions.
You would get rid of the 2.5 by subtracting 2.5 on both sides, then the equation becomes
3x=3.6
solve for X by dividing 3 on both sides
2[(9 - 5)^5 / 8] = 2[4^5 / 8] = 2[1,024 / 8] = 2[128] = 256
