đây là nơi hok toán, lần sau đừng hỏi nhé ^^
Câu a)
Do O nằm giữa 2 điểm A và B nên OA là tia đối của OB mà I thuộc tia đối của OA
=>OA<OI (cùng trên một đường thẳng )
=>O nằm giữa A và I
Câu b)
Do O cắt đoạn thẳng AB ra 2 đoạn thẳng nên OB thuộc AB Mà điểm I nằm giữa O và B
=>nên I thuộc AB hay I nằm giữa A và B.
a) \(\left(x+1\right)\left(x-2\right)< 0\)
\(\Leftrightarrow\hept{\begin{cases}x+1>0\\x-2< 0\end{cases}}\Leftrightarrow\hept{\begin{cases}x>-1\\x< 2\end{cases}}\Leftrightarrow-1< x< 2\) (đúng)
Hoặc \(\hept{\begin{cases}x+1< 0\\x-2>0\end{cases}}\) (vô lý)
=> \(-1< x< 2\)
b) \(\left(x-2\right)\left(x+\frac{2}{3}\right)>0\)
Bất đẳng thức xảy ra khi 2 thừa số đồng dấu .
\(\left(1\right)\hept{\begin{cases}x-2>0\\x+\frac{2}{3}>0\end{cases}}\Rightarrow\hept{\begin{cases}x>2\\x>\frac{-2}{3}\end{cases}}\Rightarrow x>2\)
\(\left(2\right)\hept{\begin{cases}x-2< 0\\x+\frac{2}{3}< 0\end{cases}}\Leftrightarrow\hept{\begin{cases}x< 2\\x< \frac{-2}{3}\end{cases}}\Rightarrow x< \frac{-2}{3}\)
Vậy \(\hept{\begin{cases}x>2\\x< -\frac{2}{3}\end{cases}}\) thì thõa mãn
a) Để (x+1)(x-2)<0 khi x+1 và x-2 trái dấu
Mà x+1 > x-2 nên \(\hept{\begin{cases}x+1>0\\x-2< 0\end{cases}\Leftrightarrow\hept{\begin{cases}x>-1\\x< 2\end{cases}}}\)
=> -1 < x < 2
Vậy -1 < x < 2
b) Đề \(\left(x-2\right)\left(x+\frac{2}{3}\right)>0\) khi x+2 và \(\frac{2}{3}\) cùng dấu
Với x+2 và \(x+\frac{2}{3}\) cùng dương : \(\hept{\begin{cases}x-2>0\\x+\frac{2}{3}>0\end{cases}}\Leftrightarrow\hept{\begin{cases}x>2\\x>\frac{-2}{3}\end{cases}}\Rightarrow x>2\)
Với x+2 và \(x+\frac{2}{3}\) cùng âm : \(\hept{\begin{cases}x-2< 0\\x+\frac{2}{3}< 0\end{cases}\Leftrightarrow}\hept{\begin{cases}x< 2\\x< \frac{-2}{3}\end{cases}}\Rightarrow x< \frac{-2}{3}\)
Vậy x>2 hoặc x < \(\frac{2}{3}\)
1/This road isn't large enough for us to cycle
2/Nam buys some presents for me
3/Van reiceves Mai a ruler
4/She isn't tall enough to reach the picture
\(\frac{x}{2}-\frac{1}{y}=\frac{2}{3}\)
<=>\(\frac{x}{2}-\frac{2}{3}=\frac{1}{y}\)
<=>\(\frac{3x-4}{6}=\frac{1}{y}\)
<=>\(y\left(3x-4\right)=6\)
Ta có bảng sau:
| 3x-4 | -6 | -3 | -2 | -1 | 1 | 2 | 3 | 6 |
| y | -1 | -2 | -3 | -6 | 6 | 3 | 2 | 1 |
| x | -2/3 | 1/3 | 2/3 | 1 | 5/3 | 2 | 7/3 | 10/3 |
Vì x;y là số nguyên nên có 2 cặp số nguyên thỏa mãn là ..........
