प्रथम चतुर्थांश में \(x+2y\le 10\), \(3x+y\le 12\) की साझा सीमा का प्रतिच्छेद कौन-सा है?
In the first quadrant, what is the intersection of the shared boundaries \(x+2y\le 10\), \(3x+y\le 12\)?
Explanation opens after your attempt
C. (\left\(\frac{14}{5},\frac{18}{5}\right\))
Concept
Solving (x+2y=10) and (3x+y=12) gives (\left\(\frac{14}{5},\frac{18}{5}\right\)). Fractional vertices are also valid in graphs.
Why this answer is correct
The correct answer is C. (\left\(\frac{14}{5},\frac{18}{5}\right\)). Solving (x+2y=10) and (3x+y=12) gives (\left\(\frac{14}{5},\frac{18}{5}\right\)). Fractional vertices are also valid in graphs.
Exam Tip
रेखाओं (x+2y=10) और (3x+y=12) को हल करने पर (\left\(\frac{14}{5},\frac{18}{5}\right\)) मिलता है। भिन्न वाले शीर्ष भी ग्राफ में मान्य होते हैं।
