For this case we have the following inequality:
[tex]r + 6 \geq11[/tex]
To solve we have:
Subtracting 6 from both sides of the equation:
[tex]r \geq11-6\\r \geq5[/tex]
Thus, the solution is given by all values of r greater than or equal to 5.
Answer:
The solution is given by all values of r greater than or equal to 5.
