1st comment yay!!
supposed to be 5-3x=10+7x
I understand this quite well now
Just as we learned in class
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 :)
Video- Again, this video was great! :)
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.
x = apples sold
y = bananas sold
z = income
I believe it would make a geometric plane. Been awhile since I took Geometry :)
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.
Hazel, I don't think that all three variables can be the slope because what would mean?
Great video! The PANDEMIC game seems really complicated.
Maybe we will play Pandemic during the Exponential unit!
Great video... Looks like what we did in class
I'm getting the hang of it.
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.
This is getting much easier i understand this a lot better now!
how do you know if its a negative or a subtract sigh
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:
10 - 3 = 10 + -3
subtracting a negative actually adds!
10 - -3 = 10 + 3
You also see this when we circle the terms. When we combine the like terms, we are adding them all together, so a 10 - 3 would be adding a negative 3 to the 10.
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!!
...I understand if you think I'm a lunatic.
(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.
A fraction can be eliminated by multiplying by its reciprocal (flipped version)
3/4x = 6
multiply both sides by 4/3
4/3(3/4x) = 6(4/3)
4/3 multiplied by 3/4 is just 1 so it eliminates.
x = 6(4/3)
with fractions we multiply by the top and divide by the bottom
x = 6 times 4 divided by 3
x = 24 divided by 3
x = 8
I think I get it.
ok this makes sense...
Hi sorry i thought i had commented when i watched this
hi. nice videuz
In the beginning you said that you could only add or subtract what would happen if you multiplied
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?
