Find the highest common factor and lowest common multiple of the following pairs of numbers using prime factorisation 60 and 75

100 points, hi, i’m not sure how to get the equation from the graph and table.

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.

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?
