Answer:
neither
Step-by-step explanation:
First, arrange the equations to fit the y=mx + b format
1. 2x - 3y = 8
y = -2/3x - 8/3
2. -x + 4y = 2
y = 1/4x + 1/2
Equations that are parallel have the same slope.
In perpendicular equations, one slope would be x and the other would be -1/x (negative reciprocal)
The equations are neither parallel nor perpendicular, so neither.

Answer:
0.4
Step-by-step explanation:
so, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer

<em>I think it's wrong because for some reason scientists are permitted to do this but that is breaking the law. I hate how they do it because these are just innocent animals that did nothing wrong to us, our scientists just decide it's ok to go stick needles in them and put stuff on them. My biggest problem with this is that they don't care about the effects their products have on innocent animals and instead of fixing their mistake and just apply it to humans, they just keep on going like there's no tomorrow. Animals have done nothing wrong to these people and I think that it's wrong to do so. Also, I don't really think that this proves anything. An animal's skin and fur are different than a human's skin and hair so it would make no sense to test these things on them because it really is guaranteed to give an accurate answer. Animals differ from us in so many ways that you should be able to think that scientists wouldn't harm these lovely creatures, but instead, they do. Why do scientists hurt these animals? I don't want to live in a world with hurt animals, especially when some of them have World Records, like the Sea Otter.</em>
