Question

The bisectors of the angle between the lines 2x+y=4 and 2x+4y=5 is

Answer 1

Answer:

2x-2y=3

Step-by-step explanation:

bisectors of angle between lines =  a1x+b1y+c1  

                                                         √a1∧2+b1∧2

2x+y-4=0

2x+4y-5=0

2x+y-4/√4+1 = 2x+4y-5/√4+16

2x+y-4/√5 = 2x+4y-5/√20

2x+y-4/√5=2x+4y-5/√4*5

2x+y-4=2x+4y-5/2

(2x+y-4)*2=2x+4y-5

2x-2y=3

Hope it helps.

Answer 2

Given:

The angle between the lines 2x+y=4 and 2x+4y=5

To find:

find the y value

Step-by-step explanation:

$2x+y-4=0;2x+4y-5=0$

$2x+y-4=2x+4y-5$

$2x-2x=4y-y-5+4$

$3y-1=0$

$3y=1$

$y=\frac{1}{3}$

Answer:

The y  value of $y=\frac{1}{3}$
