I was able to see that the cold water took longer for the diffusion and the hot water was really fast. almost half the time. I am assuming that it is because the molecules move much more quickly in the hotter water. Am I correct?

yes! and dividing by 6 would make sense because it would read x<2 or x is less than 2.

You know, that is entirely obvious, I think I'm just making things too difficult by overthinking them. Thanks much for shaking me out of that stupor.

You have excellent grammar and reasoning, but the first thing they taught me in high school is never begin a paper with "I'm going to write about..." or "This paper is going to be on..." Maybe that is the way they told you to write this paper, and if so,...

Not that I can think of...I think I remember using a line graph where you circle the number (2 in the last case) and since it is not equal to x, you don't darken it in, then draw a line that extends to all numbers less than 2. x is somewhere in there.

If this is underlined < that means it is less than and equal to. No line just means less than. I explained this problem earlier, it looks harder, but it's the same. Get rid of the number beside the x by division.

Yes! You got it! If you check back with my line explanation, since it is underlined, you darken in the circle and draw in a line for every number less than 3

It depends, but If you are quoting or paraphrasing, I believe you can say "blahblahblah(Frankenstein)." remember to put the period after the citation, no matter how you do it, with a title or name.

Yes. Draw a line from -5 to 5 and fill it out from there.

you have to isolate the x or the y. So move the 5x to the other side by subtraction,-4y=8-5x, then divide each part by -4, -4y/-4=(8/-4)-(5x/-4). Gives you y=-2+5/4x. Now plug that y into the original equation. 5x-4(-2+5/4x)=8... then once you get x plug...
