कौन सा बिंदु \(2x+y\geq 7\), \(x+2y\leq 12\), \(x\geq 0\), \(y\geq 0\) का हल है?

Which point is a solution of \(2x+y\geq 7\), \(x+2y\leq 12\), \(x\geq 0\), and \(y\geq 0\)?

Correct Answer

B. ((3,3))

Step 1

Concept

Substituting ((3,3)) gives (2x+y=9) and (x+2y=9). In point testing, check every inequality separately.

Step 2

Why this answer is correct

The correct answer is B. ((3,3)). Substituting ((3,3)) gives (2x+y=9) and (x+2y=9). In point testing, check every inequality separately.

Step 3

Exam Tip

((3,3)) रखने पर (2x+y=9) और (x+2y=9) मिलता है। बिंदु जांच में सभी असमानताओं को अलग-अलग जांचें।
