`Steps:` To Prove Its Not A Pic I Wrote In The Middle

`6k+9>k-1`

`\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides},\\6k+9-9>k-1-9`

`\mathrm{Simplify},\\6k>k-10`

`\mathrm{Subtract\:}k\mathrm{\:from\:both\:sides},\\6k-k>k-10-k`

`\mathrm{Simplify},\\5k>-10`

`\mathrm{Divide\:both\:sides\:by\:}5,\\(5k)/(5)>(-10)/(5)`

`\mathrm{Simplify},\\k>-2`

`The\:Correct\:Answer\:Is\:k>-2`

Answer 2

k > - 2

Explanation:

subtract k from both sides

5k + 9 > - 1 ( subtract 9 from both sides )

5k > - 10 ( divide both sides by 5 )

k > - 2
