Find the indicated derivatives, using the following information:

f(9)=−5\displaystyle {f{{\left({9}\right)}}}=-{5}  g(9)=2\displaystyle {g{{\left({9}\right)}}}={2} 
 f′(9)=−1\displaystyle {f}'{\left({9}\right)}=-{1}   g′(9)=−3\displaystyle {g}'{\left({9}\right)}=-{3} 

(fg)′(9)\displaystyle {\left({f}{g}\right)}'{\left({9}\right)} =  

(fg)′(9)\displaystyle {\left(\frac{{f}}{{g}}\right)}'{\left({9}\right)}=
