The generic equation of the circle is given by:

Where,
r: radius of the circle
(xo, yo): center of the circle.
The center of the circle in this case is:

The radius of the circle is:

Substituting values we have:

Rewriting the equation we have:
Answer:
The general form of the equation of a circle with center at (a, b) and radius of length m is:
option A
The answer is -30.
Why: If x = 10, then you fill in -2(10 + 5). Do -2 times 10 and -2 times 5. The new equations is (-20 + -10). When you add two negatives, the answer will be a negative so the answer is -30.

Answer:
4 hours
Step-by-step explanation:
Alright, so Steve has $50 in his pocket. He wants to rent a bike for the maximum amount of time possible with his money. It costs him $12 per hour to rent a bike.
To solve this problem use simple arithmetic:
($50/$12=4.16)
So Steve is able to rent the bike for 4.16 hours, but we aren't done yet. Steve cannot purchase 16% of an hour, he can only buy FULL hours, so with his $50 , the maximum amount of time he can buy is 4 hours!
Let me know if you need any further explanations :)
