Answer:
(2, -3) and r = 3.
Step-by-step explanation:
you can also plug this equation in desmos but I guess it's good to know how to do it also:
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2
Now in order to make a perfect square on both sides, we need to do this:
First add 9 to both sides:
x^2 + 6x + 9 + y^2 -4y +4 = 9.
I purposely shifted it to show the perfect square created when you add 9 to both sides. Factor:
(x+3)^2 + y^2 - 4y + 4 = 9.
now the second bolded part is allso a perfect square. Factor:
(x+3)^2 + (y-2)^2 = 9
Based on the equation of a circle, the center must be at (2, -3) and the radius is the square root of 9 which is 3.

Down and maximum I think I know down is right for sure but I’m not sure about the other one
Assuming that she goes every day of the month and one month has 30days:
Let the fee per class of Fit Fast be x.
Let <span>the fee per class of Stepping Up be y.
Let </span><span>the fee per month of Stepping Up be z.
Fit fast fee(if she does for this choice) - 30x
Stepping up fee</span><span>(if she does for this choice) - 30y + z
Im not sure of what the costs are as you did not state but here it is...hope this helps:)</span>
