1st comment yay!!

supposed to be 5-3x=10+7x
10/12/2015 12:42:50 pm
I understand this quite well now
10/12/2015 12:48:30 pm
Just as we learned in class
10/12/2015 12:58:27 pm
That looks like what we did in class today

Question- Say there were three variables in an equation... 7x+3a+1b=10x+8a+3b...this is relatively easy to simplify... but would it translate to the slope intercept form for a linear line or would this equation math up to a different function family/line? We would solve for each variable... would all three variables be the slope? (<--doesn't seem like that idea would make much sense :)

I didn't even get what you just said there. And yeah, I wouldn't say that idea made very much sense.

Whoa, three variables! Well, first off we can only "solve" for one variable meaning there can only be an "x" in the equation to find the exact value. When we have two variables it creates a Line with lots of possible solutions. And when we have three variables it creates some kind of 3D line/figure! Save that question for Ms. Brown's Geometry class. Luckily in this class we will only be dealing with the relationship between TWO variables.

You can have three variables though. An example would be selling two different products.

Hey I couldn't watch the video but I'm able to comment. I will try later but I pretty much understood you in class.

Great video! The PANDEMIC game seems really complicated.
10/12/2015 04:54:18 pm
Maybe we will play Pandemic during the Exponential unit!
10/12/2015 02:37:41 pm
Great video... Looks like what we did in class
10/12/2015 02:45:24 pm
I'm getting the hang of it.
10/12/2015 04:00:57 pm
I got it to work. cool video

I agree with Hazel that if you do the problen right then it will be different function family then linear. I think that is why we are not using three variables. Great question Hazel!

I may not have been in class today but this seems fairly simple.
10/13/2015 04:47:21 am
This is getting much easier i understand this a lot better now!
10/13/2015 09:55:13 am
how do you know if its a negative or a subtract sigh
10/13/2015 02:06:23 pm
Negative signs and subtraction signs work the same way. They both reduce the amount. If it helps change every subtraction sign to a plus negative:

There is an online game called pandemic...only that you're playing as the disease. You're trying to try to kill the entire world. I finnally beat the game...by killing everyone! MWAHAHAHAHAHAHA!!

(You should be expecting things like this from her! It's normal!)

Sorry hiiiii my comment didn't load

The only thing I don't really understand that well is how we do fractions.
10/14/2015 08:24:03 pm
A fraction can be eliminated by multiplying by its reciprocal (flipped version)
10/16/2015 08:20:07 pm
I think I get it.

10/22/2015 06:39:37 pm
ok this makes sense...
10/25/2015 05:50:31 pm
Hi sorry i thought i had commented when i watched this
10/26/2015 03:15:34 pm
hi. nice videuz
10/26/2015 04:14:35 pm
In the beginning you said that you could only add or subtract what would happen if you multiplied
11/4/2015 06:25:38 pm
In class today you said that if the problem was g=#g+5 (#=number) that this would get people confused will we see any problems like this? If we do then how would we change it according to the problem without using x or y as a variable?
