The first one is B and the second is D
The equation of the circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have:
![r=10\\(-3,\ 6)\to h=-3,\ k=6](https://tex.z-dn.net/?f=r%3D10%5C%5C%28-3%2C%5C%206%29%5Cto%20h%3D-3%2C%5C%20k%3D6)
Substitute:
![(x-(-3))^2+(y-6)^2=10^2\\\\(x+3)^2+(y-6)^2=100](https://tex.z-dn.net/?f=%28x-%28-3%29%29%5E2%2B%28y-6%29%5E2%3D10%5E2%5C%5C%5C%5C%28x%2B3%29%5E2%2B%28y-6%29%5E2%3D100)

Answer:
23
Step-by-step explanation:
Given Shane hits 5 HRs out of 100 At-bats,
![\frac{x}{460} = \frac{5}{100} \\\frac{x}{460} (460) = \frac{5}{100} (460)\\x = 23](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B460%7D%20%20%3D%20%5Cfrac%7B5%7D%7B100%7D%20%5C%5C%5Cfrac%7Bx%7D%7B460%7D%20%28460%29%20%3D%20%5Cfrac%7B5%7D%7B100%7D%20%28460%29%5C%5Cx%20%3D%2023)
I don’t understand the question
If you mean
7m-4
M=8, this is the solution
7(8)-4
56-4
=52
But if you mean
7m- - 4
As in - + - = +
Then this is your answer
7(8)+4
56+4
=60
