Can someone me i need with the question asap.

find the value of k so that the function f is continuous:
f(x)= {9x^2-4/3x-2, x≠-2/3 }
k , x=-2/3

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.
