असमानताओं \(x+2y\leq 8\) और (x+2y>4) का संयुक्त ग्राफ कैसा है?
What is the common graph of \(x+2y\leq 8\) and (x+2y>4)?
Explanation opens after your attempt
D. एक ओर बंद और दूसरी ओर खुली पट्टीStrip closed on one side and open on the other
Concept
The condition becomes \(4<x+2y\leq 8\). The boundary (x+2y=8) is included, but (x+2y=4) is excluded.
Why this answer is correct
The correct answer is D. एक ओर बंद और दूसरी ओर खुली पट्टी / Strip closed on one side and open on the other. The condition becomes \(4<x+2y\leq 8\). The boundary (x+2y=8) is included, but (x+2y=4) is excluded.
Exam Tip
शर्त \(4<x+2y\leq 8\) मिलती है। (x+2y=8) शामिल है लेकिन (x+2y=4) शामिल नहीं है।
