If the lines \(x^2+2 x y-35 y^2-4 x+44 y-12=0\) and \(5 x+k y-8=0\) are concurrent, then \(k\) equals
- A 4
- B 3
- C 2
- D 1
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
Since, we know that, point of intersection of pairs of line represented by \(\begin{aligned} & a x^2+2 h y x+b y^2+2 g x+2 f y+c=0 \text { is } \\ & \qquad\left(\frac{h f-b g}{a b-h^2}, \frac{g h-a f}{a b-h^2}\right)\end{aligned}\) For the lines,…
