Desperately need help with Algebra II!!!

[Prussian to the Iron]

Ok, so after losing everything for an undefined amount of time due to a bad Algebra II test, I have decided to ask for help here.

I will not ask you guys to do my tests for me (I take online school at CDIS, google it), but if I have trouble, then I'll post some of the sample questions. I'm sure that having you guys explain it will be much better than the crappy(and sometimes non-existent) descriptions given. I know that this will be solely out of the good of your hearts (wow, I'm posting this on the internet?), but I truly need help here, and I failed Geometry and had to re-take it last year. Every other class I excel in for some reason, including Biology...

So thank you to anyone who is willing to help me. I wish I had something other than my gratitude to offer.

[Lord Winter]

I'm sure there would be plenty of people (me included) who would be glad to answer any questions you have.

[Prussian to the Iron]

Sure glad I didn't get the stereo-typical "Oh yeah well we're teh intarwebz ur failin ahahahahahah!" sort of response. Nice to know that some people would help. Thanks!

[Beefy187]

I think I did alright in Algebra.. Integration is where my mathematics life began to go down the hill.

Could you post some sample question so I know I'm on the right page?

[Hooahguy]

i got a B+ in the Alg2 course as a final grade and a D on the final exam. but i can try to help.

[Prussian to the Iron]

hey, thats kinda funny Hooahguy! I just happened to get a D on my Medieval Hsitory final, and a B+ in the class. Those damned Rennaiscance artists are what killed me...DAMN YOU TITIAN!!!

I'll put up a sample tomorrow.

[pevergreen]

We didn't do too badly at math did we beefy?

Whats the quadratic forumula?

[Megas Methuselah]

I aced my Calculus and other inferior math classes back in high school with ease, mah man. Ya need some help? Come buy some meth! I'm everything you'll ever need, the answers to your life's questions...

[Prussian to the Iron]

Ok, this is the test I bombed on (7/20). I wanna see if you guys get it right, because now I have the feedback and answers. Not doubting you guys or anything, just like to make sure.

[LittleGrizzly]

2 a

5 what graph ?

I love Algerbra but have to goto work...

[Prussian to the Iron]

sorry, lots of them are images (like the fractions) so they wont come over with a copy+paste. didnt see that one!

[Beefy187]

We didn't do too badly at math did we beefy?

Whats the quadratic forumula?

Until grade 10. Grade 11 is when I got lost and never bothered to pick up...
So its been about 3 years since I last properly picked up a math book.

Quadratic formula is that thing! Formula which is quadratic!

Got number 2 right lol
Rest, I will do when Carp wins

[naut]

sorry, lots of them are images (like the fractions) so they wont come over with a copy+paste. didnt see that one!

Print-screen and upload?

Long time since I've done any maths other than Financial maths. Not that I'm unhappy about that though.

[Prussian to the Iron]

ah yes, but my keyboard has no print screen. laptop you see.

[pevergreen]

15 is A)

y = mx + c is the standard format for the thingy. M is the gradient and C is y-intercept.

Rest are in terms we don't use in Queensland, or need images etc

I'm pretty sure most (if not all) laptop keyboards have a print screen function. It may just be in blue, under a function key.

[Hooahguy]

hey, thats kinda funny Hooahguy! I just happened to get a D on my Medieval Hsitory final, and a B+ in the class. Those damned Rennaiscance artists are what killed me...DAMN YOU TITIAN!!!

I'll put up a sample tomorrow.

same thing with Chemistry. i got an F on the final exam, B+ on the final grade. the reason? i owe it all to CuteWolf, and how he helped will be a secret between me and him....

[LittleGrizzly]

3 B (assuming dimes = 10)

11 C (though im not sure..)

13 D (guessing this one really...put some thought into it though...)

18 C (its just a case of counting really)

20 Couldn't Y be anything ?

[Centurion1]

I am in AP Calculus BC and skipped algebra 2 so i hope that i can help you.


From about 5 minutes of work i can tell you

2 is b
9 is -7/10
10 is -2
11 is c
13 is d
15 is b


A lot of the questions are unanswerable because of missing images.

If you need more help just pm i will guide you through it.

Oh and try www.physicsforum.org i find that it can help a whole lot and their "mods" literally do nothing but help people solve problems.

[TevashSzat]

If it helps.....I'm in Penn's Math 114 class which is Calculus II. Thats a bit of a misnomer really since its basically a little of differential equations and then multivariable/vector calculus. Weird thing is I already know the 240/241 stuff.....which is differential equations + linear algebra.....

Anyways, math is something that you just have to practice. Preferably if you can understand the concept quickly, you won't have to do much or any at all but I suppose that isn't the case for you and algebra 2 right now. I'd recommend you to just basically do all the problems in your textbook without looking at the answers beforehand.....most schools usually offer tutors too so it wouldn't hurt to contact them.

[pevergreen]

15 is b

Its quite possible I'm wrong, but would the y not become negative when moving it over to the other side of the equation to put it in standard form?

A is in standard form (as per my post, y = mx + c), gives the correct gradient and y intercept, no?

[Megas Methuselah]

same thing with Chemistry. i got an F on the final exam, B+ on the final grade. the reason? i owe it all to CuteWolf, and how he helped will be a secret between me and him....

I remember your secret when I read your conversations on yo profile wall, bro!

I NEED HELP WITH DATA ANALYSIS (STATISTICS)! HELP ME!!! (this is true)

[Azathoth]

Lol, Algebra 2. I remember when it was still just Math A and Math B.

y = mx + c is the standard format for the thingy. M is the gradient and C is y-intercept.

NAY! It's y = mx + b, and b is the slope, and it's called slope-intercept form! Standard form is Ax + By + c = 0.

[pevergreen]

NAY! It's y = mx + b, and b is the slope, and it's called slope-intercept form! Standard form is Ax + By + c = 0.

I have no idea what this slope intercept form is.

Maybe im thinking of one for a straight line. Most likely.

[LittleGrizzly]

Maybe instead of just giving you answers you could tell us the ones you had trouble on, and whoever is able to solve it can give you a basic explanation of how...?

Probably learn more that way... (or the tutoring idea is probably better but more effort as well)

[Prussian to the Iron]

well, I'm fairly sure you guys could help me pretty well. so If I have any trouble with a question I'll post it; but PM me instead, because I end up having to search for relevant posts.

[Ferret]

2 is b

6x4 is 24

[Prussian to the Iron]

shouldnt 2 be A then? 8*4 is too much?

[Subotan]

No economics?

I NEED HELP WITH DATA ANALYSIS (STATISTICS)! HELP ME!!! (this is true)

What type of stats? Regression? I got an HD in stats last semester. (I wish I was doing as well in my Law class )
