we used these functions to represent the two sides of the equation:
f(x) = 3x
g(x) = 4x + 1
graph the functions y = f(x) and y = g(x) on the same coordinate plane.
at which points are the functions y = f(x) and y = g(x) equal? what are the x-values of the solution?
how many solutions are there to the equation f(x) = g(x)? how do you know these are solutions?

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8  feet of ribbon. he cut off one piece that was 3 5/8  feet long and another piece that was 1 1/4  feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.

In trapezoid abcd, ac is a diagonal and ∠abc≅∠acd. find ac if the lengths of the bases bc and ad are 12m and 27m respectively.

Can someone explain to me how to do
