Answer
B)
Step by step explanation
The standard form of circle when center(h, k) and radius r, given is
(x - h)^2 + (y - k)^2 = r^2
Given: (h, k) = (5, 0) and r = 3
Now plug in these values in the standard form, we get
(x - 5)^2 + (y - 0)^2 = 3^2

Therefore, the answer is B) 
Thank you :)
Answer:
25. Yes, it is a function, because none of the x outputs are repeating
Answer:
No
Step-by-step explanation:
The answer would be B. because the father you go down the right the more greater it will be, so -7 would be less than -3 and -6 would be less than -5. Do you get it?
Hope this helps :)
