कौन सा बिंदु \(x+2y\le9\) और \(3x+y\le11\) दोनों की सीमा रेखाओं के प्रतिच्छेद पर है?
Which point is at the intersection of the boundary lines of \(x+2y\le9\) and \(3x+y\le11\)?
Explanation opens after your attempt
A. ( \left\(\frac{13}{5},\frac{16}{5}\right\) )
Concept
Solving (x+2y=9) and (3x+y=11) gives \(x=\frac{13}{5}\), \(y=\frac{16}{5}\). Fractional vertices are common in graphical solutions.
Why this answer is correct
The correct answer is A. ( \left\(\frac{13}{5},\frac{16}{5}\right\) ). Solving (x+2y=9) and (3x+y=11) gives \(x=\frac{13}{5}\), \(y=\frac{16}{5}\). Fractional vertices are common in graphical solutions.
Exam Tip
(x+2y=9) और (3x+y=11) हल करने पर \(x=\frac{13}{5}\), \(y=\frac{16}{5}\) मिलता है। भिन्नात्मक शीर्ष भी ग्राफीय हल में सामान्य हैं।
