Since there is no feasible region defined, there is no answer possible.
If we knew the values of 'x' and 'y', and the boundaries of the feasible region, we could answer that question quickly and easily.
It would depend on the feasible region.
To determine the maximum and minimum values of the objective function (4x + 9y), you need to specify the constraints of the problem, such as inequalities or boundaries for (x) and (y). Without these constraints, the function can theoretically increase indefinitely. If you provide a feasible region or constraints, I can help calculate the maximum and minimum values based on those limits.
Since x and y can get smaller and smaller without a limit, there is no minimum for the value of 3x+3y.
(1/x) + (1/y) + (1/z) is a minimum value when x=y=z=10. Symmetry gives either maximum or minimum value.
It is 18.
2x+2y
The answer depends on the feasible region and there is no information on which to determine that.

maximum value of 6y+10y
(6x)(5y)
14
The answer obviously depends on what the boundaries of the feasibility region are.
