Anais a math tracher noticed that the average grade on an exam, G, given that n students watch the related video can be given by the function G(n)=50+1.5n.

95 - 1.5m

Step-by-step explanation:

G(S(m))=G(30-m)

=50+1.5(30 - m)

simplify

=50+1.5(30 - m)

=50+45 - 1.5m

=95 - 1.5m

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse
