Answer 3

do you know how to graph inequalities?

Answer 4

Yes, but the last part is confusing. The f(x,y)

Answer 5

Did you get a graph like the one above?

Answer 6

Once you have the graph, pick out the points that make up the corner of the region, then plug them into f(x, y).

For example,
\[f(3, 6)=9(3)+5(6)=27+30=57\]

Answer 7

f(4,2)=9(4)+5(2)=36+10=46?

Answer 8

right. so now do (9, 9) to see which one give the max

Answer 9

f(9,9)=9(9)+5(9)=81+35=116

Answer 10

So the maximum would be 9,9?

Answer 11

yes
