This is interesting. You cannot turn 1/4 or 2/4 or 3/4 into a mixed number because they are proper fractions. Perhaps ask your teacher about it? Or just rewrite the fractions as is and state they are in proper form.
Same with 7. They are each simplified already. I would suggest asking your teacher.
I think it’s six because 3n=6-5 3 n=6-5 then subtract 5 5 from 6 6
(-3, 2) because you take the derivative and youll get y'=2x+6 then solve for x and that is -3 then put -3 in the original equation and you get 2
