HELP MEEE!! Please evaluating a compound. Inequality using a graph

Irina-Kira [14]

Answer:

$\frac{x}{2}$

Step-by-step explanation:

From the graph, we can conclude that,

$x$ is less than 2 and not including as there is a hollow circle at the mark 2.

Also, $x$ is greater than or equal to 7 including 7 as there is a solid circle at the mark 7

So, the compound inequality will be $x$

Now, the option that simplifies to the above inequality is the required answer.

Let us check the first option.

$\frac{x}{2}$

Therefore, option 1 simplifies to the above compound inequality.

So, the correct answer is option 1.
