Question

Find the value of p, if the straight lines x + p=0, y+2=0 and
3x +2y +5=0 are concurrent​

Answer 1

Answer:

3

Step-by-step explanation:

$y + 2 = 0 \\ y = - 2 \\ \\ 3x + (2 \times - 2) + 5 = 0 \\ 3x + ( - 4) + 5 = 0 \\ 3x + 1 = 0 \\ 3x = - 1 \\ x = \frac{ -1 }{3} \\ x = - 3 \\ \\ p + x = 0 \\ p + - 3 = 0 \\ p = + 3$
