Whats the answer? ( Khan Academy ) Also Ill give branliest if its correct!

Which linear equations have an infinite number of solutions? check all that apply.  (x  –  3/7)  =  2/7(3/2x  –  9/14)8(x  +  2)  =  5x  –  1412.3x  –  18  =  3(–6  +  4.1x)(6x  +  10)  =  7(x  –  2)4.2x  –  3.5  =  2.1 (5x  +  8)

What is the order of these fractions from least to greatest 2/3 7/10 5/8 65/100

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
