कौन सी असमानता रेखा (2x+3y=18) के ऊपर वाले अर्ध-तल को दर्शाती है?
Which inequality represents the half-plane above the line (2x+3y=18)?
Explanation opens after your attempt
B. \(2x+3y\ge18\)
Concept
Writing the line as \(y=\frac{18-2x}{3}\), the upper side is \(y\ge\frac{18-2x}{3}\). This is equivalent to \(2x+3y\ge18\).
Why this answer is correct
The correct answer is B. \(2x+3y\ge18\). Writing the line as \(y=\frac{18-2x}{3}\), the upper side is \(y\ge\frac{18-2x}{3}\). This is equivalent to \(2x+3y\ge18\).
Exam Tip
रेखा को \(y=\frac{18-2x}{3}\) लिखने पर ऊपर का भाग \(y\ge\frac{18-2x}{3}\) है। यह \(2x+3y\ge18\) के बराबर है।
