Would acceleration be a curve, or a straight line?

Some info from the problem:
Object is accelerating, starting from rest
Accelerates for 4 seconds
Changes position from 2m to 10m

So, how would you find acceleration and then how would you show this on a velocity vs. time graph

Thanks!

I have two angles (EAF and JAD) that share A as a vertex. The both look vertical. The book wants me to prove that the are vertical. There are no markings.

Okay, I'm taking Algebra 1 this year, and we have this project where we get a year (my year is 1900) and make a math problem out of it.

The math problem that I made is:

[(867*2)-(7*204)]*(1896/316)+[... (The whole thing doesn't show up, but only the first part is important).

Well, I know that the problem equals 1900 (I made up the problem and checked it), but I don't understand if I'm supposed to use brackets in the problem, or if it's correct just to put an extra set of parentheses like: ((867*2)-(7*204)).

This is for a major grade project, so I need to know which is the correct way of writing the problem please!

What are the 2 points that these equations go through?
(or something like that, my teacher said not to graph them just dinf the 2 points)

1. y = -3/5x - 12/5

2. 2/3x + y/3 = -1/3

3. 3/5y - x/5 = -6/5

4. 4/5 = - 1/3x - 3/4y

I'm currently thinking of a sci-fi story steeped in realism and I have an alien race with multiple arms/appendages. Would it be possible for such a race to play at least two different kinds of instruments simultaneously? It would be great if I could get some proof or reassurance from musicians themselves and perhaps a biologist as well. Thank you.
