कौन सा बिंदु (x+2y=8) सीमा पर है और साथ में \(x-y\leq 1\) को भी संतुष्ट करता है?

Which point lies on the boundary (x+2y=8) and also satisfies \(x-y\leq 1\)?

Explanation opens after your attempt
Correct Answer

A. ((2,3))

Step 1

Concept

At ((2,3)), (x+2y=8) and (x-y=-1). Thus it lies on the boundary and also satisfies the second inequality.

यदि ((k,2)) बिंदु \(2x+y\leq 10\) और (x-y>1) दोनों का हल है, तो (k) की सही सीमा कौन सी है?

If the point ((k,2)) is a solution of both \(2x+y\leq 10\) and (x-y>1), which range of (k) is correct?

Explanation opens after your attempt
Correct Answer

B. \(3<k\leq 4\)

Step 1

Concept

Substitution gives \(2k+2\leq 10\) and (k-2>1). Hence \(k\leq 4\) and (k>3).

Step 2

Why this answer is correct

The correct answer is B. \(3<k\leq 4\). Substitution gives \(2k+2\leq 10\) and (k-2>1). Hence \(k\leq 4\) and (k>3).
