Answer:
![x \leq -7](https://img.qammunity.org/2021/formulas/mathematics/high-school/mea3c71d8o5gzs0z96imklafuoqv2sw1bq.png)
The graph has a closed circle.
–7 is part of the solution.
Explanation:
Given
![15 \geq 22 + x](https://img.qammunity.org/2021/formulas/mathematics/high-school/yah0nt2u2hkgkr6iaekudi6q84g1yqe4kn.png)
Required
Select 3 options from the given list of options
![15 \geq 22 + x](https://img.qammunity.org/2021/formulas/mathematics/high-school/yah0nt2u2hkgkr6iaekudi6q84g1yqe4kn.png)
Subtract 22 from both sides
![15 - 22 \geq 22 - 22+ x](https://img.qammunity.org/2021/formulas/mathematics/high-school/82ol62spy1vqgzoofeprgtve0gz6rz67pc.png)
![-7 \geq x](https://img.qammunity.org/2021/formulas/mathematics/high-school/vvizbqysv0ovvhdzn4lqwedhimxigb02zr.png)
Swap positions of the expression; Note that the inequality sign will change
![x \leq -7](https://img.qammunity.org/2021/formulas/mathematics/high-school/mea3c71d8o5gzs0z96imklafuoqv2sw1bq.png)
This means x less-than-or-equal-to negative 7
There are two options left to select;
The inequality sign in
implies that the graph has a close circle.
Inequality signs such as
and
signifies a close circle
There is only one option left to select;
Lastly;
Split the expression
into two
We have:
or
![x = -7](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ezbjdmhlci01nncqvyudzvo22qxmazuywb.png)
Because
,
Then, -7 is also a part of the solution
