Circle formula: (x - h)² + (y - k)² = r² ; where (h,k) is the vertex & "r" is the radius
Since the radius is 4, (x - h)² + (y - k)² = 4² → (x - h)² + (y - k)² = 16
1) If you have two points, replace "x" and "y" with the coordinates to create two equations with unknown variables "h" and "k".
2) Then solve the system to determine the value of "h" and "k".
3) Input the values of "h", "k", and "r" into the Circle Formula.
The answers are A, C, and D. B is not a correct answer because 4 times 11 is not 42

Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:

Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:
