A counseled at my school is opinion charged of the books, and her birthday is on the 19th of December!

well, that's good to know!

lol!

Wow, DS !!!....we're born only two days apart....mine's on the 19th....of course, I'm a twin, so I know at least ONE person who has the same BDay as me  !!!!

An easier one please? Too dificult to understand...

I am getting ready. I go to school at 7:15, not at 7:00 AM!

I thought you had to go to school Dragon  

If he's only got £2.75 to spend on dog food for the whole year the dog is going to starve!

Probably yes... Probably no... I don't know...

This might mean x⁴ - x + 1 = 0

However, there are no real solutions to this.  There are 4 complex solutions given (approximately) by:

0.7271 - 0.43i

-0.7271 - 0.9341i

0.7271 + 0.43i

-0.7271 + 0.9341i

See for yourself;

what graph Chris?

you think 

$$\\4^{-x}+1=0\\
4^{-x}=-1\\
\frac{1}{4^x}=-1\\
4^x=-1\\
4^x \mbox{ cannot be negative so there is no real solution (Thanks for reminding me Alan.)}$$

So.....I assume we have

x⁴ - x + 1 = 0     ???

December 21st, or on the first day of winter!

Yes you are probably correct Dragon  

Studio di funzione 

Help

x in the power of 4 -x +1=0 ?????

Well, you can restate it. 

4-^x+1=0

but the equation will not become true. 

So, Melody is a big time champion!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

april the 16th for me.  

Probably we have to find out how much the dog food costs per day to find how many it costs per year... I am a bit confused on this one... For example, 2 dog food bags per day, and we have to find the cost and how much bags he buys... That's what i think...

x=5

It really does, it equals 5

But there are no powers here.  

Have a good day Dragon.  

How much he can buy in a year would depend on how rich he is wouldn't it Dragon?

We don't know how rich he is.  

How many £2.75 of dog food for a year can he buy? 

Thats how I think of the question...

5st^2+5st^2

the letters and the powers are exactly the same so you can add them

10st^2

There is no question here.  

Ok. Later I will cause I got to go to school! Bye!
