Question

4x-3y-7=0, 2x+py+2=0,6x+5y-1=0​

Answer 1

Answer:

The following lines are concurrent 4x-3y-7=0,2x+py+2=0,6x+5y-1=0​

To find:

Find the value of p.

Solution:

From given, we have,

The following lines are concurrent 4x - 3y - 7 = 0, 2x + py + 2 = 0, 6x + 5y - 1 = 0​

The condition for lines to be concurrent is that, the determinant of these lines forming a matrix should be equal to 0.

So, we have,

= 38p - 152

⇒ 38p - 152 = 0

38p = 152

p = 152/38

p = 4
