यदि \(x\ge1\), \(y\ge2\), \(x+y\le8\) हैं, तो हल क्षेत्र के शीर्ष कौन से हैं?
If \(x\ge1\), \(y\ge2\), \(x+y\le8\), what are the vertices of the solution region?
Explanation opens after your attempt
A. ( (1,2) ), ( (6,2) ), ( (1,7) )
Concept
The boundaries (x=1), (y=2), and (x+y=8) give ( (1,2) ), ( (6,2) ), and ( (1,7) ). Do not treat shifted restrictions as simple \(x\ge0\), \(y\ge0\).
Why this answer is correct
The correct answer is A. ( (1,2) ), ( (6,2) ), ( (1,7) ). The boundaries (x=1), (y=2), and (x+y=8) give ( (1,2) ), ( (6,2) ), and ( (1,7) ). Do not treat shifted restrictions as simple \(x\ge0\), \(y\ge0\).
Exam Tip
सीमाएं (x=1), (y=2) और (x+y=8) से ( (1,2) ), ( (6,2) ), ( (1,7) ) मिलते हैं। बदले हुए अक्षीय प्रतिबंधों को साधारण \(x\ge0\), \(y\ge0\) न मानें।
