कौन-सी प्रणाली प्रथम चतुर्थांश में बंद बहुभुज नहीं बनाती?
Which system does not form a closed polygon in the first quadrant?
Explanation opens after your attempt
Correct Answer
C. \(x+y\ge 5\), \(x\ge 0\), \(y\ge 0\)
Concept
The first-quadrant region \(x+y\ge 5\) extends outward infinitely. A closed polygon needs bounds in every direction.
Why this answer is correct
The correct answer is C. \(x+y\ge 5\), \(x\ge 0\), \(y\ge 0\). The first-quadrant region \(x+y\ge 5\) extends outward infinitely. A closed polygon needs bounds in every direction.
Exam Tip
\(x+y\ge 5\) वाला प्रथम चतुर्थांश क्षेत्र बाहर की ओर अनंत फैलता है। बंद बहुभुज के लिए हर दिशा में सीमा चाहिए।
