Alright, weird question, but it's for art stuff in school. =P

 

We have to create a design for a tattoo, and now first they want us to look up all sorts of different tattoos and the origins of it and stuff like that. Anyone who knows any good sites about tattoos with a lot of information?

 

I'm just posting this here cause some people might be bored and looking for something to do, and this isn't all that boring to help out with. =P

 

http://www.bmezine.com for peoples experiences and ideas

 

and there's a tattoo design category on deviantart.com

 

stuff about tattoo history, http://www.tattoos-by-design.co.uk, http://en.wikipedia.org/wiki/History_of_tattooing

I've never heard the term 'sahelmontane', but the Sahel is obviously the region of Africa you're talking about and montane is a high altitude grassland. See here.

 

That makes a lot more sense, thank you!

Simultaneous Equations

Okay, im usually good at these but ive forgotten how to do a couple of them. Please explain how to solve these with the 'elimination method' if that makes sense.

 

1) x+6y=9

2x + 3y=19

 

2)Add the Equations:

5x-2y=1

4x+2y=8

Posted

I: x+6y=9 |*2

II: 2x+3y=19

______________ (subtract II-I)

-9y=1 -->y=-1/9

 

then put -1/9 for y in one of the equations:

 

x+6*(-1/9)=9

x=9+2/3

x=29/3

 

 

the second one is the same I think.

Yes, I get the same answers as you (but I doubled the second equation).

 

For the second, you can just add the 2 equations:

 

9x = 9

x = 1

y = 2

i think youre right but i dont really understand

:(

Right:

 

I'll start with the second question:

 

5x - 2y = 1 I

4x + 2y = 8 II

 

I + II => 5x - 2y + 4x + 2y = 1 + 8

=> 9x = 9

=> x = 1

substitute into I:

=> 5 - 2y = 1

=> -2y = 1 - 5

=> -2y = -4

=> 2y = 4

=> y = 2

 

First question:

 

x + 6y = 9 I

2x + 3y = 19 II

 

2(II) => 4x + 6y = 38 III

III - I => 4x + 6y - (x + 6y) = 38 - 9

=> 4x + 6y - x - 6y = 29

=> 3x = 29

=> x = 29/3

substitute into I:

=> 29/3 + 6y = 9

=> 6y = -2/3

=> y = -1/9

 

By the way, => means implies, and the roman numerals (eg. I, II, etc.) are numbering the equations so that I can refer to them.

Any ideas about the phrase "do you enjoy your work?" in German... I should really know that yet it's the only thing I can't figure out in the talk I have for tomorrow...

I know how to say "three weeks ago", not that you care anymore- "il y a trois semaines".

What's the formula in excel to get it to work out the difference between 2 cells?

 

=ABS(A1-A2)

 

But obviously replace the A1/A2 with the relevant cells. This gives the difference, the absolute difference (no negativity); I assume that's what you meant.

Does anyone know how to make excel draw a regression line of best fit through a set of points? I downloaded an addon that supposed to do it, but it didn't work quite how I wanted it to.

 

Ideally, I'd like to apply different types of regression to different parts of the curve.
