\(A=\dfrac{27-12x}{x^2+9}=\dfrac{x^2+9+27-12x}{x^2+9}-1=\dfrac{x^2-12x+36}{x^2+9}-1=\dfrac{\left(x-6\right)^2}{x^2+9}-1\ge-1\)

Dấu = xảy ra khi x = 6

Vậy:...

x\(\le\)11

=>3(x-1)-2(x-2)<=6/4(x-3)

=>3x-3-2x+4<=3/2x-9/2

=>-1/2x<=-9/2-1=-11/2

=>x>=11

                                  Tạm biệt một thời gian, OLM.

This night is cold in the kingdom
I can feel you fade away
From the kitchen to the bathroom sink and
Your steps keep me awake

Don't cut me down, throw me out, leave me here to waste
I once was a man with dignity and grace
Now I'm slipping through the cracks of your cold embrace
So please, please

Could you find a way to let me down slowly?
A little sympathy, I hope you can show me
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

Let me down, down
Let me down, down
Let me down, let me down
Down, let me down, down
Let me down
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

Cold skin, drag my feet on the tile
As I'm walking down the corridor
And I know we haven't talked in a while
So I'm looking for an open door

Don't cut me down, throw me out, leave me here to waste
I once was a man with dignity and grace
Now I'm slipping through the cracks of your cold embrace
So please, please

Could you find a way to let me down slowly?
A little sympathy, I hope you can show me
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

Let me down, down
Let me down, down
Let me down, let me down
Down, let me down, down
Let me down
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

And I can't stop myself from falling down
And I can't stop myself from falling down
And I can't stop myself from falling down
And I can't stop myself from falling down

Could you find a way to let me down slowly?
A little sympathy, I hope you can show me
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

Let me down, down
Let me down, down
Let me down, let me down
Down, let me down, down
Let me down
If you wanna go then I'll be so lonely
If you're leaving baby let me down slowly

If you wanna go then I'll be so lonely
If you're leaving baby, let me down slowly

\(\dfrac{-5x+7-2x+3-3x+4}{2-x}=\dfrac{-10x+14}{2-x}=\dfrac{-2\left(5x-7\right)}{2-x}=\dfrac{2\left(5x-7\right)}{x-2}.\)
