Algebra Help

THIS IS FREE! NOT limited to Algebra.

If anyone here needs help with Algebra, or some other math, I may be able to help. I can only go up to 10th grade math though, which is Algebra 2.
I may also be able to help with other subjects(i.e. history, science, physics)

I WILL NOT do your homework for you. I will, however give you answers to the best of my ability, or memory(whichever takes me further).

Just remember: If you are just looking for answers, and not how to solve the problem, you will be in trouble on the tests. So if you need help understanding anything, please ask. I can't promise a right answer, but I can try.

 

x^2 = 144. What is x?

 

Zomg?!?! I think it's something like 12. I may be wrong.

 

-12 and 12

 

good joke. 12

 

It was a test. You forgot -12.

 

As did I, lol.

 

ANy Algebra? Try this one.


(2^2 6^7 )^8
(---------)
(7^3____)


It's a fraction, solve it.

 

I said up to 10th grade if you read the first post... Can't give an answer that won't look ridiculous, tbh.

 

Ok,here.

2x+90=5x+180


Solve for X

 

>_>
All he'd have to do is graph it on a TI83 and look for the zeroes/intercepts. Not difficult.

 

Try this.

Use the fundamental identities to simply. Show all steps.

(4cosx - 3sinx)^2 + (3cosx + 4sinx)^2

hint: Expand then use the first pythagorean identity.

 

X= -30

 

Edit: oh damn he beat me to it haha.

Anywhom... guna find mine hitman? lol.

 

Leaving now. PM me if you are SERIOUS about help. Ty.

 

Well I don't need much help in math , I am best at math, but if I may this is very simple: Write an equation of a line perpendicular to y=4/5x + 7. I made that one up as I went along so I don;t know the solution yet but I will do it in my head after I post this.

 

so are you looking for vouches for this??? or are you just bored and a math geek and want to help people??

 

perpendicular would be y=4/5x-23

EDIT: anything with the coefficient of x being 4/5 would be perpendicular to that line

 

nice idea, if anyone needs help with up to Calc BC i can help

 

Oh, how I love the TI83. And oh how i hate how we were not allowed to use them in precal and half of cal...

Edit: We just started with limits and derivitives last week. The basic formula for figuring crap out is...


Not to incredibly hard, just really tedious if you have a problem with a lot of foiling. Like the other day we had one with 34 "parts" (for lack of a better word) once it was expanded all the way thru foiling. Annoing trying to go back and find something if you messed up.
