यदि रेखा (y=-(p+3)x+18) (x) के (4) बढ़ने पर (y) (36) घटाती है, तो (p) क्या है?
If the line (y=-(p+3)x+18) decreases (y) by (36) when (x) increases by (4), what is (p)?
Explanation opens after your attempt
C. (6)
Concept
The slope is (-(p+3)), and the decrease is (4(p+3)=36). So (p+3=9) and (p=6).
Why this answer is correct
The correct answer is C. (6). The slope is (-(p+3)), and the decrease is (4(p+3)=36). So (p+3=9) and (p=6).
Exam Tip
ढाल (-(p+3)) है और कमी (4(p+3)=36) होगी। इसलिए (p+3=9) और (p=6) है।
