Question

a pair of linear equation 4x+ky+8=0 and 4x+4y+2=0 represent parallels lines then the value of k is​

Answer 1

Answer:

HOW TO SOLVE?

For parallel lines,

$\frac{a1}{a2} = \frac{b1}{b2}$

Now, this becomes

$\frac{4}{4} = \frac{k}{4} \\ 4k = 16 \\ k = \frac{16}{4} \\ k = 4$

The value of k must be 4. So, that the equations become parallel to each other.

HOPE IT HELPS YOU!!!

Answer 2

Answer:

4

Step-by-step explanation:

a1/a2=b1/b2

4/4=k/4

4k=16

k=16/4

k=4
