Question:

The region represented by the system of inequalities $x, y ≥0, y ≤6, x + y ≤3$

Options:

is a bounded region in the first quadrant

is an unbounded region in the first and second quadrant

is an unbounded region in the first quadrant

has no point which satisfies all the inequalities

Correct Answer:

is a bounded region in the first quadrant

Explanation:

The correct answer is Option (1) → is a bounded region in the first quadrant

Constraints: x≥0, y≥0 ⇒ first quadrant.

x+y≤3 ⇒ region lies below the line x+y=3 with intercepts (3,0) and (0,3).

y≤6 is redundant since y≤3 already from x+y≤3 and x≥0.

Intersection is a triangle with vertices (0,0), (3,0), (0,3) ⇒ bounded in first quadrant.

Answer: is a bounded region in the first quadrant.
