असमानताओं \(x\ge 0\), \(y\ge 0\), \(x+3y\le 9\) से बने त्रिभुज का (x)-अवरोध कौन-सा है?
What is the (x)-intercept of the triangle formed by \(x\ge 0\), \(y\ge 0\), and \(x+3y\le 9\)?
Explanation opens after your attempt
C. ((9,0))
Concept
Putting (y=0) gives (x=9). Hence the vertex on the (x)-axis is ((9,0)).
Why this answer is correct
The correct answer is C. ((9,0)). Putting (y=0) gives (x=9). Hence the vertex on the (x)-axis is ((9,0)).
Exam Tip
(y=0) रखने पर (x=9) मिलता है। इसलिए (x)-अक्ष पर शीर्ष ((9,0)) है।
