Answer:
Center: 
Radius: 
Step-by-step explanation:
-According to the following equation, the center would be , because the center is known as 
from the equation of a circle. To find the radius, you would only need to square root the simplified radius from the following the equation and you would get the radius 15:
The equation of a circle:
The following equation:
Center: Radius: 
Answer:
7. k^4
8. m^6
9. 18x^4
10. 35u^8v^4
11. 6561
12. x^6 y^24
13. 16a^6 b^11 c^2
14. -8f^5 g^6 h^5
15. 81p^9 t^10
Step-by-step explanation:
B is correct
12/3=4
-> 3 x 4 = 12
39/500 needs to be multiplied by 15, which results in 585/500. This is 1.17 as a decimal. 191/200 in diameter needs to be multiplied by 8, which equals 1528/200. This is 7.64 as a decimal.
So just try it for x=1 how many will get for y
y+3=2(x-1) for x = 1 will get y+3 =2(1-1) so y+3=2*0 so y+3=0 so y=-3
x=1
y=-3 so choice A.(1,-3) is right sure
hope this will help you
