Well you guys beat me to it. I'm glad that more of you posted questions today.
Sally: For 2 ACE 12A you need to write an equation for profit in terms of the number of posters sold. What this means is you need to end up with a final equation where P = ...something n. To do this, you need to solve for x in the second equation and substitute that back into the first equation.
Anna: For 2 ACE 29 you need to use FOIL. If you have a graphing calculator, then input the equation and see where the min. and max. points are, etc. If you don't, then we'll go over it tomorrow. I'm sure others will have the same question.
Rockersquirrel: If you are writing an expanded expression such as x^2 - 5x + 6 in factored form what would help is if you look at each term seperately. Think about what two numbers give you a product of +6 and a sum of -5. It would be -2, -3. From that my factored form would be (x-2)(x-3). Another example: x^2 +9x - 36. Once again, what two numbers give you a product of -36 and a sum of 9? It would be +12, -3. Factored form would be (x+12)(x-3).
y iz no wun there!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
okay rockersquirrel. I am having difficulty translating your text. You know how you have those time zone problems, well the time on this website could be one of those.
Anna....as long as your are able to multiply/distribute/use foil on 2 ACE 29 and do it correctly (so make the rectangle boxes to check) then it's fine. I'll go over the graphing part in class to help answer a,b,c,d. If I forget, remind me.
Welcome Mark, Please read the comments posted to Anna regarding 2 ACE 29. Main thing is that you can rewrite the factored form into expanded form. We will do the actual a-d in class tomorrow using the graphing calculators.
In equation 2, n=20-x. Solve for x like you would a 1 or 2 step equation.
In equation 1, P= xn-6n. Substitute the result you got above for x into this equation. So it should look like P = (whatever you got for x)n-6n. Multiply out/distribute, combine like terms and you should end up with P = ......something n
rockersquirrel, Please limit yourself to posting a question about the assignments. We will not be using a webcam, sorry. This site is math related only. If you haven't counted yet, I did, you have alot of posts tonight. I'm glad your having fun, but how many are math related?
rockersquirrel, I thought you said the rest was easy????
If you have an increase in salary such as a 15% raise that is the same as your current salary (100%) + 15% or 1.15. So if the salary increase by 1.12 that the same as a 12% salary increase. If her salary increases by 110% what would that look like as a decimal or what the are referring to as a factor?

Ohhhhhhhhhh... Now i get it!!!
sry...i kinda put sum stuff on the other periods wun...oops
r u there? if u r, let mi know...
can u get that thing where u hav 2 type in those letters to make sure that ur not a cumpewter off please...its reeeeeeeeeeeeeelly anoying!!!
wutz up with meybff???
by the way....it's not 8:50...its onlee 6:47!!!
u need 2 fix it...k?
y iz no wun there!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
do i have to come to you in the morning or will we just go over it in 6th period?
brb
hi antee anna!!!
brb
gotta get mee sum cappucceeno!!!
k...im back
the word verification is getting reely irritating!!!!!!!!!
4 12. a., would p=(20-x)(x-6) work???

helloooooooooooooooooooooo?
any budy home?
sry...
ooopz...
i mean, "sorry"
wut about the word verification thing?
can u change that?
er delete it or sumthing
rockersquirrel,
this is not a chat room. Post questions and comments. Sounds like you are refueling with cappucino to get some caffeine.
Please read my post to Sally above. Your final equation needs to be P=...something n. There should be no x's in the equation.
i dont under stand 29 it is hard
ya...i guess that im sorta trying to stay awake with my coffee/cappaccino.
ohhhhhhh. i gess i didnt understand the equation.
ms. gusman: i cant see sally's one...):
mark: hi

nvr mind...i see it!
...but i cant think uv anything....
rockersquirrel.
Go all the way to the top. It's in the first post. Too much cappucino?
Rockersquirrel,
You don't need to "think of anything" use the two equations that they give you.
who iz sally?
...yah.
...i dont get it...
...
do i hav 2 do that double step thingy?
rockersquirrel
the goal is to get P =.....something n
In equation 2, n=20-x. Solve for x like you would a 1 or 2 step equation.
In equation 1, P= xn-6n. Substitute the result you got above for x into this equation. So it should look like P = (whatever you got for x)n-6n. Multiply out/distribute, combine like terms and you should end up with P = ......something n
yah....i need help..
H E L P !
ooooooooooooooooooooooooooooooh
could it be 20-6n?
Okay,
I'm taking a 15 minute break.
...yay!!!!!!! i fiqured it out...but im not gonna tell....
there could be others lisening...
(:
nooooooooooooooooooooooooooo!!!!
neeeeed mooooore cooooooffeeeee!!!!!
28.....
this iz kinda simple...
Hi. Nathan here! I do not understand question 29. Can you help explain please?
ms. gusman: you should apply web cam chat...that would be a bit easier...
hahahahahahahahahahahahaahahah
lolololololololoololololollolo
jonathan maybe you could help me understand # 29?
by
;nathan
29 iz sooooooo hrd....
):
ur on ur own kid
hey i got it!!!!
lol
30. (-_-) \m/
the rest iz all easy!!!
what do you do if its x5/x8?
would u get x.3?
ms. gusman?

Nathan,
Look for comments to Anna and Mark regarding 2 ACE 29.
what do they mean by a factor of 1.12 for 36.b?
sry....
PS i think nathan left...
rockersquirrel
x^5/x^8 is the same as
x(x)(x)(x)(x) divided by
x(x)(x)(x)(x)(x)(x)(x)
five x's in the numerator cancel out five x's in the denominator. You are left with three x's in the denominator. Your numerator is 1. (so 1/x^3)
what do they mean by a factor of 1.12 for 36.b?
thnks
do they mean 112%?
...
rockersquirrel,
I thought you said the rest was easy????
If you have an increase in salary such as a 15% raise that is the same as your current salary (100%) + 15% or 1.15. So if the salary increase by 1.12 that the same as a 12% salary increase. If her salary increases by 110% what would that look like as a decimal or what the are referring to as a factor?
when they say, her sallary grows by 1.12, is it growing from the previous answer, or the $30,000?
If you have anymore questions, look for me before school.
oohh..
k bye
good night...
rockersquirrel,
Last comment for tonight. They are always applying the increase to her original salary of $30,000.
oh makes sense now =)
oh and eagle is nathan
