यदि (y=(k+6)x+1) (x) के (4) बढ़ने पर (y) (52) बढ़ाती है, तो (k) क्या है?
If (y=(k+6)x+1) increases (y) by (52) when (x) increases by (4), what is (k)?
Explanation opens after your attempt
C. (7)
Concept
The slope is (k+6) and (4(k+6)=52). Therefore (k+6=13) and (k=7).
Why this answer is correct
The correct answer is C. (7). The slope is (k+6) and (4(k+6)=52). Therefore (k+6=13) and (k=7).
Exam Tip
ढाल (k+6) है और (4(k+6)=52)। इसलिए (k+6=13) और (k=7) है।
