Your grandmother has collected Christmas ornaments all of her life and has finally decided to give away 30, each year. After 10 years, she should only have 60 ornaments left, enough to decorate a
single tree. Write an equation to model the situation.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

b, i believe, but not sure.
