What is the solution to 3|–3x + 9| = –18?
x = –5
x = 5 or x = 1
x = –5 or x = 1
no solution
do the math its for my final review need to understand it.

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.

The sum of these consecutive integers is equal to 9 less than 4 times the least of the integer. find the three integers
