Cool :)

Sorry but I don't understand, its like a graph right? like x axis and y axis  

Malaysia ;)

Calebmok:

Btw where you from?

Me from Hong Kong :)

Answered!! :)

It is me again!!

Let's isolate the y.

3x - 2y = 6

2y = 3x - 6

y = 3/2 x - 3

Solve for a and b:

Plug in the values into the slope-intercept equation as (a,3) and (-2,b) are ordered pairs:

3 = 3a/2 - 3

3a/2 = 6

3a = 12

a = 4

b = (3/2)(-2) - 3 = -6

Find the value of 2b + 5a:

2b + 5a = 2(-6) + 5(4) = 8

@both of you , new question! thx!

Thanks VERY MUCH!!!! Wow youre quick....more question coming!!

This is a science question Btw

but I think its because green ink should be above the solvent...not in the solvent. The green ink would dye the solvent green if they did it this way.....(not sure).

Maybe we should write it as a summation......

\(\sqrt[3]{x-a}=\displaystyle\sum^{\infty}_{n=0}\left(-\dfrac{x}{3}\right)^n\left(-a\right)^{\frac{1-3n}{3}}\)

To make the sign alternate:

\(\sqrt[3]{-a}=-\sqrt[3]{a}\)

At least this is true according to my knowledge.

Yes you are very awsome Max - you are also very modest NOT

I  was looking at this expansion in Wolfram Alpha 

expansion of (-a+x)^(1/3)

and the expansion is

There is an obvious pattern here except why are both the first two terms + and then the signs alternate.  

Why is that ?

Perhaps I should have put this as a new question but it is sideways related to this question ://

:)

I know how to do :):) I am very awesome:):)

1)

 \(\sqrt{75360} - \sqrt{0.7536}\\ =\sqrt{7.536 \times 100^2} - \sqrt{75.36\times \left(\dfrac{1}{10}\right)^2}\\ =100\sqrt{7.536} - \dfrac{1}{10}\sqrt{75.36}\\ = 100 \times 2.754 - \dfrac{1}{10}\times 8.681\\ = 275.4 - 0.8681\\ =274.5319\)

2)

90% of the questions = 45 questions.

Let x be the number of questions he got correct.

(45-x) be the number of questions he got wrong.

\(5x + (-2)(45-x) + 0(50 - 45) = 176\\ 5x - 90 + 2x = 176\\ 7x = 266\\ \color{red}\boxed{\color{black}{x=38\\ 45-x = 7}}\)

He got 38 questions correct, and 7 questions wrong.

Yes I could not do any LaTex until I was on this forum.  I didn't learn the basics here because back then this forum did not have Latex.  Mr Massow added it for us quite a bit later :) 

But smart kids like you and Max and MathsGod can learn it really quickly if you put your mind to it.  :)

(-1)^(1/3) = -1

because (-1)^3 = -1

me? LOL

I started learn LaTeX by myself when I was first in the forum.

PS: I am 14 :)

Perfectly clear, thank you so much Omi67! Finally I get it.

You could get really good too !!        

You could get  really good too !!       

You know Ninja, you are a smart kid - yes I know you already know that LOL

I think you should start to learn some Latex.  It is easy, you can learn it a little at a time and think how smart you will look then! :))

Take this line

(x)^1/3 + (x - 16)^1/3 = (x - 8)^1/3

 It is not to the power of 1 it is to the power of 1/3 so put the 1/3 s in parentheses.  Like this

(x)^{1/3} + (x - 16)^{1/3} = (x - 8)^{1/3}

Now copy that line onto your clipbard

now open the latex tab and copy it in.

like this

\((x)^{1/3} + (x - 16)^{1/3} = (x - 8)^{1/3}\)

Now if you copy what I have done you will have used LaTex for the first time :))

If you have questions make sure you ask.

We have had at least one boy on here before, I think he was a lot younger than you, and he got really good at LaTex. 

 10xsquared - 27x + 5 = 0

you can use the quadratic formula

(x)^1/3 + (x - 16)^1/3 = (x - 8)^1/3------------Cube each side

3 (x - 16)^(1/3) x^(2/3) + 2 x + 3 (x - 16)^(2/3) x^(1/3) - 16 = x - 8 -------------Isolate all radicals

3 (x - 16)^(1/3) x^(2/3) + 3 (x - 16)^(2/3) x^(1/3) = -x + 8 

idk what to do from here LOL. Thats what we learned in school with square roots. But that is Algebra 2 and this is NOT algebra 2! I am about to go to school and gonna see if my teacher can do it and get back to you.
