The functions f and g are both defined on the domain of all real numbers with f(x)= x*2 and g(x)= 3x+5

write equations for the functions f•g and g•f

h(x)= (1/3x+5)*2 what are the domain and range of h?

find an equation for a function k so that h is equal to one of these compositions f•k k•f g•k k•g or f•k•g answer asap

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?
