Answer: 2x+4y=5 on edge

Step-by-step explanation:

Solve for y for all equations and choose the one that would make parallel lines. Since a is the only one with the same slope and different y intercept, it's the only one that would make the lines parallel.

X+ 2y=5
X=5-2y

2x+4y=3
2(5-2y)+4y=3
10-4y+4y=3
10=3

5x+2y=3
5(5-2y) +2y=3
25-10y+2y=3
-8y=-22
Y=-22/-8

Y=2.75

6x+12y=30
6(5-2y)+12y=30
30-12y+12y=30
30=30

3x+4y=8
3(5-2y)+4y=8
15-6y+4y=8
-2y=8-15
-2y=-7
Y= -7/-2
Y= 3.5

mojhsa [17]

This is a physics problem.

The law is that the momentum is preserved: total momentum before collsion = total momentum after collision

Momentum before collision = 80 kg.m/s - 100 kg.m/s = -20 kg.m/s

Then answer is b. - 20 kg.m/s
