SOLUTION: can you help me with problem? it is from a multiple choice hand out. f is a function defined by f(x)= -x/5 and g is a funciton defined by g(x)= 7-3x then 4g-5f= thanks for

You can put this solution on YOUR website!
When you say 4g you're saying 4*g(x) which means that you're going to multiply 4 by the output g(x). So if I plug in x=0 for g(x) I get


So 4*g(0)=4(7)=28.
Now we're going to do this in terms of x




So 4 times g(x) plus 5 times f(x) is 28 minus 11x. I hope this makes sense.
