f (x) = x + 5 and g(x) = x2 − 2x

Nneeedd 1.find the residual if you know the actual number is 5.2 and the predicted value is 4.8

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.

Me find the value of x each figure.
