प्रथम चतुर्थांश में \(x+4y\le 20\) और \(3x+y\le 18\) की सीमाओं का कटान कौन-सा है?
In the first quadrant, what is the intersection of the boundaries \(x+4y\le 20\) and \(3x+y\le 18\)?
Explanation opens after your attempt
Correct Answer
B. (\left\(\frac{52}{11},\frac{42}{11}\right\))
Concept
Solving (x+4y=20) and (3x+y=18) gives (\left\(\frac{52}{11},\frac{42}{11}\right\)). Do not avoid fractions when finding exact vertices.
Why this answer is correct
The correct answer is B. (\left\(\frac{52}{11},\frac{42}{11}\right\)). Solving (x+4y=20) and (3x+y=18) gives (\left\(\frac{52}{11},\frac{42}{11}\right\)). Do not avoid fractions when finding exact vertices.
Exam Tip
(x+4y=20) और (3x+y=18) हल करने पर (\left\(\frac{52}{11},\frac{42}{11}\right\)) मिलता है। सटीक शीर्ष के लिए भिन्नों से डरें नहीं।
