Answer 1

Given:

The compound inequality is

$9$

To find:

The solution for the given compound inequality in interval notation.

Solution:

We have,

$9$

Subtracting 6 from each side, we get

$9-6$

$3$

Divide each side by 3.

$\dfrac{3}{3}$

$1$

Here, 1 is not included in the solution set and 3 is included in the solution set.

Therefore, the solution in interval notation is (1,3].
