किस (k) के लिए (y=410-(k-8)x) रेखीय क्षय दिखाएगा?
For which (k) will (y=410-(k-8)x) show linear decay?
Explanation opens after your attempt
A. (k>8)
Concept
For decay the effective coefficient must be negative. From (-(k-8)<0), (k>8).
Why this answer is correct
The correct answer is A. (k>8). For decay the effective coefficient must be negative. From (-(k-8)<0), (k>8).
Exam Tip
क्षय के लिए प्रभावी गुणांक ऋणात्मक चाहिए। (-(k-8)<0) से (k>8) मिलता है।
