What is the general form of the equation of a circle with center at (a, b) and radius of length m?
x2 + y2 β 2ax β 2by + (a2 + b2 β m2) = 0
x2 + y2 + 2ax + 2by + (a2 + b2 β m2) = 0
x2 + y2 β 2ax β 2by + (a + b β m2) = 0
x2 + y2 + 2ax + 2by + a2 + b2 = -m2

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
