Question 971254
a) f(x)+g(x) = [(3x+2)/(5x-7)] + [(4x)/(5x-7)]
             = [(3x+2+4x)/(5x-7)]
             = (7x+2)/(5x-7)
the domain for (a) is all real except 7/5 which is 1.4

b) f(x)/g(x) = [(3x+2)/(5x-7)]/[(4x)/(5x-7)]
             = [(3x+2)/(5x-7)]*[(5x-7)/(4x)]
             = (3x+2)/(4x)
the domain for (b) is all real except 0
