Desperately need help with Algebra II!!!

[Aemilius Paulus]

Well, I can try to help you. I am an all-A student and I had A's in all my semesters and semester exams related to Maths, but I but I barely got an "A" in Algebra II. Currently, I am taking College Algebra, and the class will start in precisely one hour from this post time (I am typing this in the Uni library). So I suppose I can help, even though I consider myself an imbecile in maths, despite my perfect grade record (not to mention some dubious things I occasionally did to get A's - asking students which problems were on the test and such ). Really, I have gotten A's in Geometry and Algebra II mainly because of my spectacular luck with teachers, times, students, and etc.

In any case, use this site. I use it to check all my work. Mathway is a godsend for any struggling Maths students. Get the paid membership if you can - it will aid you in the understanding of how to solve problems, step-by-step, as opposed to the free just-answer-the-problem function.

And like I said, feel free to PM me any questions - I will see if I can help out. I deeply emphasize with you, as I struggled to get A's in mathematics myself. Although I did have my mother to help me out, who was maths professor and then an accountant, so that may explain my relative success... Life is not fair in other words, and I wish I can help you.

Ugh. Stuff like conditioned probabilities (That's the easiest part), margin intervals, etc. I fail completely at math. Although I was awesome at Economics. But then again, my economics exam didn't involve much math.

In any case, use this site.

wow. that wasn't even able to solve a simple question of naming a slope of a line that passes through 2 points. thanks anyway though

Business stats stuff? Yeh. I can help with that if you need.

Trust me, I have used the site for two years. I never, ever had problems with the stuff it said it could do.

In fact, just two days ago, I did a take home quiz for College Algebra class, and checked all the work entirely on MathWay (finding two mistakes of mine) and got a 100, or aced in other words. While half at the same time the class failed it, because it was so difficult (although it is very easy to solve it once you already have the answer).

Look, PI (hehe - pi - 3.14) just email me the problems at ss78@gmail.students.uwf.edu or simply PM me, and I will try and see if MathWay works for that problem.

Also, consider buying a TI-83 Plus calculator - I did half my work in my past Algebra II class on that brilliant calculator. The only trick is, you really have to know how to use it, and our Algebra II teacher did just that. She would teach us the lesson normally, and then, when we were done with the topic, and took a test on it, she showed us how to sue the calculator to solve the problems, for future benefit. But I was always ahead and I learned how to use the calculator myself, which was permitted, to take all the tests .

oops me make mistake, 2 is a


No dude use this site, www.physicsforum.org

Join the site and go to precalculus math help. People there will guide you through the problem. And it is free, plus you can slowly advance. i still use it for my college level physics and my calculus. It is the same layout as the .org as well which is comforting to me

Are you certain that is the correct URL? Because I get another generic search/domain-for-sale typo-squatter site...

Well, MathWay is splendid when you need a swift, and a solution free from human error. Or numerous solutions. But the site you speak of, Centurion, seems marvellous, as I will need help there too, once I get to Physics in my Uni

EDIT: here is the correct URL: http://www.physicsforums.com/

ok heres one i need help with:

Jeff can paddle his canoe 30 miles from home downstream in 2 hours. On his trip back home, he paddles upstream and it takes 6 hours. What is the rate of the current?

A. 5 mi/h
B. 10 mi/h
C. 15 mi/h
D. 20 mi/h

[PBI]

It's basically a simultaneous equations problem. If the current speed is C and the speed Jeff can paddle is P, we have:

P+C=15mph (Downstream)

P-C=5mph (Upstream)

Subtract the 2nd equation from the first and solve for C.

Spoiler Alert, click show to read: 

I get 2C=10mph => C=5mph, and P=10mph

[Centurion1]

oh sorry reenk i typed in the wrong website. It is http://www.physicsforums.com/ That should work. really it is great help ap, they should be able to answer any questions you have (besides unanswerable ones due to laws, no known answer, etc.

Out of interest, where do you live? I have never heard of Algebra II before but in Australia it's divided into 3 groups, Further, Methods and Specialist ( I am doing methods if that helps any of you)

But seriously, try using Youtube, it helped me on Quadriatic formulas a while ago...

[coalition]

By the way, reading all these posts tells me all of you are all a bunch of A grade students

Don't worry, I am one too

I'm fairly sure I don't want to base my Algebra II grade off of something on youtube.

[pevergreen]

Why not?

Youtube (to be honest, it was youtube of a tv show, Chopper Read teaching about OH&S) helped me to pass Economics.

What, you do not believe me? US schools, even the somewhat elite one I go to, are easy enough to make all A's if one simply lifts their rump. And it is not like Australia or UK have better schools. UK actually exhibits lower test scores than US on the same exams. Now, Asian or certain European school systems, especially in Eastern Europe are tough, but that is entirely different. And if I did not make all A's, how would I be enrolled in a Uni when I just turned 16??

16 in university? How many grades did you skip?

Kinda embaressing for me reading that comment, heh

Jesus, I will be 18 when I start entering University, you have totally outdone me

[pevergreen]

Dont feel bad, I went to school with a kid who graduated 10 days after turning 16. He had started doing uni subjects at...14 1/2?

Yeah...He also heads up a company that the mob I work for uses, and he just bought the old head office building of the mob I work for...

It's scary when that happens, I can say that I am jealous of these people, I would do anything to have a brain that good.....

I enjoy the unique perspective on life that I hold right now, and thus consider myself superior to all humans in a certain regard. Being someone else would rob me of this advantage.

[LittleGrizzly]

I wouldn't be too jealous.. I personally would find it a little awkard being 16 with 18 year olds and older only in my classes... theres advantages and disadvantages...

This stuff (or some of it) is what I did in my physics and mechanics* classes

*Newtonian mechanics, no oil!

AP between going to univesrity early and your what is a hook up comment the other day I now get a mental image of sheldon from Big Bang Theory everytime I read your posts...

I wouldn't envy the brilliant too much how lonely must it be to be 'above' people, might as well be on a deserted island.

[Prussian to the Iron]

back on topic please? heres something i really have no clue how to do:

[Ironside]

13. C
14. A
15. C
16. D
Not rally sure what they ask about in 16, but D gives 2 f(X) with different values, usually not good for functions at this math level.

[Ferret]

C, A, C

13. I assume it means gradient when it says slope and seeing as it increases by $2 for every topping added the gradient is 2/1=2

14. No idea what the question means (American terminology must be different) but (15.6, 3) is a point on the graph as when the pizza has three toppings it's price is $15.60

15. You can work out the cost of a blank pizza by taking 3x$2 away from the cost of a three topping pizza, which gives you $9.60. This function will only work when the number of toppings is greater than or equal to 3 though as you can't tell how much a two or one topping pizza will cost.

And again I have no idea what 16. is asking...

[Azathoth]

14 should be B. The equation of the line for pizza price is y = 2x + 9.6

So if x = 3, y = 15.6, or (3,15.6). Hah, if you don't like this, wait till you get to trigonometry, logarithms, and sigma notation. Although I assume you've already done some trigonometry in the last couple grades?

16's really simple. It's beginners stuff. Just use the vertical line test to see if it's a function. Literally something you learn on the first day of Functions lessons, guys.

[Ironside]

14 should be B. The equation of the line for pizza price is y = 2x + 9.6

Correct. That's what you get by not doing maths for years.
