If EF has endpoints at E(-3,10) and F(5.6) and is dilated about the origin by a factor of 7 which of the following would be the length of its image, E'F'?
6).

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
