Answer:
The inequality is given below as
[tex]r+6\ge11,\lbrace4,5,6,7\rbrace[/tex]
Collect similar terms by subtracting 6 from both sides
[tex]\begin{gathered} r+6\ge11 \\ r+6-6\ge11-6 \\ r\ge5 \\ Hence,the\text{ values that satisfies this inequality are} \\ \lbrace5,6,7\rbrace \end{gathered}[/tex]
Hence,
The final answers are
