Yes, my family owns a Sky Plus box. We love it and it was very easy to obtain and use. It records all our favorite shows we are forced to miss. You can even pause and rewind live programming !
It would depend on the feasible region.
Since there is no feasible region defined, there is no answer possible.
Feasible means possible viable means possible plus practical.
The answer depends on the feasible region and there is no information on which to determine that.
42
It is 18.
(6x)(5y)
2x+2y
14
If we knew the values of 'x' and 'y', and the boundaries of the feasible region, we could answer that question quickly and easily.
maximum value of 6y+10y
The answer obviously depends on what the boundaries of the feasibility region are.
