Thanks zegroes. Really kind.

zegroes, did you give me nagative points!?!?!!?

Math is so hard because you need to memorize them and you need to think hard, unlike English. It is hard because it is more usual that you will forget math than English. It is so difficult that it takes days to learn something really new. Hope it helps!

The real answer is 7.0685834705770348. zegroes is correct, but he just rounded it. 

To count and read numbers, you need to study.

The purpose of life is to enjoy it.

20 is the answer.

Yes. There are an infinite of solutions to solve this problem. I wrote the second easiest way to solve it.

Thanks, CPhill. Now, I gave you 5 points!

Here's an webpage devoted to that topic, DS......http://www.microsoft.com/info/cookies.mspx

The equal sign on this calculator looks like this: =

Thanks, Melody. I like it.

Use the calculator too.

Answer: 251,188,643.1507815355964985 is the answer.

NinjaDevo. I don't understand the part which you say that the calculator doesn't lie. I don't understand why the answer came as 5, when the real answer is 4.

Thanks for helping, Chris. I didn't know that was the answer. Thanks, CPhill.

Okay. I will, rosala.

Solution: 3x+y=-4 = 3*1+-7

                            = 3+-7

                            = -4

Solution (Same as above but in words): First, you write out the math problem. Then, you subsitute x and y. BUT you HAVE to subsitute x first. So, if x=1, multiply 3 by 1. After that, because you have 3 and y, so to make -4, turn y into -7. Finally, you add positive 3 and negative 7 which makes -4. That is your answer.

just put it straight into a calculator - the site one on the home page is good.

log(3)^(1/3)

or

(1/3)log(3)     They are the same

$${{log}_{10}\left({\mathtt{3}}\right)}^{\,\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)} = {\mathtt{0.781\: \!405\: \!123\: \!774\: \!393\: \!1}}$$

This is of course an approximation.  It is an irrational number.

To Solve this equation we will need to isolate either one of the variables.

For the fun of it, lets isolate the X variable.

Lets write the equation below:

$$3x+y=-4$$

Now lets us isolate the X 

Essentially, this is the answer, however you may with substitute it into the equation.

$$y=-4-3x$$

Now let us substitute:

$$3x+(-4)-3x=-4$$

Hmmm!thanks for the correction CPhill!I'll take care next time!

Thumbs up for your graph!

DS and rosala......saying that the equation can't be "solved" isn't exactly correct......it just has infinite solutions......!!!!!  (not just one solution)......there are many "x's" and "y's" which make the equation "true"......

2sin(x-60)   ......This is the sine graph shifted to the "right" by 60 degrees with an amplitude of 2......Here's the graph

So thats what i said !the equation cant be solved isnt it!

3x + y = –4   ...Rearranging this equation, we have

y = -3x - 4   ......this is the equation of a line that has infinite answers....here's a graph:

9=5*10^-10+log(x/5)  

Divide both sides by 5*10^-10 

9/( 5*10^-10 )   evaluating this, we have.......18,000,000,000

Therefore.....

18,000,000,000 = log (x/5) .........This says that......

10^{18,000,000,000} = x/5       Muktiplying both sides by 5, we have

x = 5*10^{18,000,000,000}      .......which is a REALLY BIG NUMBER   ......  !!!!!

DragonSlayer i think you didnt get me properly !(i was joking for that question is hard , what do u think i'd find such a question hard !?lol!how can that be!)

I actually meant to also say that this question is really easy!

f(x)=x^3-2x^2-5x+6

Note, that if we can add the coefficients of a polynomial and we get "0," then 1 is a root (or, zero)..therefore....

1 - 2 - 5 + 6 

-1 + 1   = 0      So 1 is a root

So, using a little synthetic division, we have

1    1  -2  -5   6

           1  -1  -6

       1 -1  -6   0

So, the polynomial that remains is     x² -x -6   which can be factored as....

(x-3) (x + 2)

And the factorization is  (x-1) (x-3) (x +2) and the rational zeroes obtained by setting each factor to 0 are 1, 3 and -2

And that's it.....
