The center of the circle is at (-2,-7) and its radius is 36.

Vanyuwa [196]

Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2

r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296

You earn $7.50 per hour at a fast food restaurant. You earned $123.75 last week. How many hours did you work last week?

ladessa [460]

I believe you would need to divide 123.75 by 7.50.

The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
