किस (k) के लिए (y=100-(k+3)x) रेखीय क्षय दिखाएगा?
For which (k) will (y=100-(k+3)x) show linear decay?
Explanation opens after your attempt
A. (k>-3)
Concept
For decay, the effective coefficient of (x) must be negative. From (-(k+3)<0), (k>-3).
Why this answer is correct
The correct answer is A. (k>-3). For decay, the effective coefficient of (x) must be negative. From (-(k+3)<0), (k>-3).
Exam Tip
क्षय के लिए (x) का प्रभावी गुणांक ऋणात्मक चाहिए। (-(k+3)<0) से (k>-3) मिलता है।
