The feasible region is in the first quadrant where both x and y are positive.
This gives: x≥0,y≥0
This eliminates Option 1 (which has x≤0,y≤0).
The feasible region is bounded by two lines:
Line 1: 3x+4y=24
Line 2: x+2y=10
Finding where the lines meet the axes:
For 3x+4y=24:
When x=0: 4y=24, so y=6
When y=0: 3x=24, so x=8
For x+2y=10:
When x=0: 2y=10, so y=5
When y=0: x=10
Using the origin (0,0) as a test point to determine the inequalities:
For line 3x+4y=24:
At origin: 3(0)+4(0)=0
Since 0<24 and the origin is inside the shaded region relative to this line:
3x+4y≤24
For line x+2y=10:
At origin: 0+2(0)=0
Since 0<10 but the origin is outside the shaded region relative to this line:
x+2y≥10
The complete set of constraints:
3x+4y≤24
x+2y≥10
x≥0,y≥0
This matches Option 4.
