Answer 1

what is

k + 6 greater than or equal to 19, if k = 11​

we have

`\begin{gathered} k+6\ge19 \\ k\ge19-6 \\ k\ge13 \end{gathered}`

For k=11

we have

`\begin{gathered} 11+6\ge19 \\ 17\ge19\text{ ----}\longrightarrow\text{ is not true} \\ \text{that means-}\longrightarrow\text{ the value of k is not a solution of the inequality} \end{gathered}`
