xx + sincos

No. [ 4+3=9 ] is just a plain old false statement.

3y=7y+24.4

First, try to get all the y-terms on the same side of the equation. Easily done here by subtracting 7y from both sides

3y-7y=7y-7y+24.4

-4y=24.4

Now divide by -4

-4y/-4=24.4/-4

y=-6.1

All of them

Do not write an equation in words!!!

What does x mean in 10y = 5x + 95x? It is a place holder for a number. Any number.

If: 7x+11y+13z = 15

Then: 7(15/21)+11(15/33)+13(15/39) = 15 because 5+5+5 =15

So it follows: 7(15/21)*11(15/33)*13(15/39) = 125 because 5*5*5 = 125

Therefore: x = 15/21 y = 15/33 and z = 15/39

Or as: x = 5/7 y = 5/11 and z = 5/13

The estimated trillion digits of pi are 27 trillion digits. An exact equal value would require an infinite number of digits and cannot be proved to any exact trillions.

(4x - 32)(x - 2) so x = 2 or 8

You really should use your calculator for such simple questions instead of posting them on WA . It requires far fewer key depressions and you get your answer quicker. However, since you are obviously incapable of carrying out even such a simple task, and the answer is 904.

they are used as variables. usually as an identified number.

x ≠ 11

9 + x = 21

9 + x - 9 = 21 - 9

x = 12

For N - Nanny goat

For U- Urchin,umbrella bird

For V- Vermin

For W- whale,wallaby,white tip shark, weasel,whale shark and etc

For Y- Yak

there are many more but i just listed a few to make it quicker

f'(x)= 99x^2 - 500x + 700 Remember: if f(x)=ax^b where a and b are constants, then f'(x)=[bax^(b-1)]/b

Yes, it's vitally important!

Would you be a manager with a bad suit or not appopriate vest???

Would you wear a home clothes to attend a social meeting?

What would you wear of you are a public speaker, even if you were George Bush?

You can't, you never do like that!

Because other people will judge you through your appearance, your clothes! If you wear unappropriate clothes, they will look at you with hamrful eyes! Your personal appearance is VERY important any time you're in a public place. People respond (or not) to you depending on how you look. It seems shallow, but that's the way it is. I personally will go out of my way to avoid interracting with kids who are "saggin". If I'd wanted to see your drawers, I'd have offered to buy you a drink... I've seen otherwise qualified job applicants lose an opportunity because they went to the interview wearing jeans and a tee-shirt. It cannot be stressed enough: YOUR PERSONAL APPEARANCE IS IMPORTANT ANY TIME YOU LEAVE YOUR HOME! (FRC) Your personal appearance should be cultivated and maintained at ALL times. It is not solely reserved for public appearance.

This quadratic expression can be arranged as:

-x2+7x+12

When factorised:

(-x+8.424428901)(x+1.424428901)

So the intercepts are: x = 8.424428901 or x = -1.424428901

The above was worked out by using the quadratic equation formula.

2 x 10-8 isn't a question. It's only a number.

If you ran into somebody who didn't understand scientific notation,

and he asked you "What does that mean?", you could write it in a

different form that might be clearer to him:

0.00000002

We wouldn't call that an "answer".

After 13 years of formal math courses followed by a lot of more years in practice,

we have no clue on how to handle an equation with six 'equals' signs in it, and

to be honest, we don't even really understand the question.

y = 2x² + 4x - 10

The axis of symmetry can be found by setting the derivative equal to zero:

y = ax² + bx + c

y' = 2ax + b = 0

x = -b/2a

Or you could just memorize the formula above.

x = -b/2a

x = -4 / (2*2)

x = -1.

x + 10

x2 + 1x - 30 = (x + 6) (x - 5)
