Best ResponseYou've already chosen the best response.0So, ive done separation of variables, and integrated dy/(y) amd dx/5 and gotten ln(y) = x/5+C, but I am not sure what to do next.

Best ResponseYou've already chosen the best response.0when x=0 y=8 plug that solve for c and yeah isolate y

Best ResponseYou've already chosen the best response.0ok, so \[\ln(y)=\frac{ x }{ 5 }+C\] becomes \[y=e^(\frac{ x }{ 5 }+C)\]

Best ResponseYou've already chosen the best response.0so 8=e^(0+c), 8=e^c?

Best ResponseYou've already chosen the best response.1yup, c=ln 8 so ln y +ln 8 = x/5 ln (y/8) = x/5 got this ?
