Answer:
[tex] \huge k \leq - 6[/tex]
Step-by-step explanation:
[tex]9k-18≤-72[/tex]
Using the addition property add 18 to both sides of the equation
That's
[tex]9k + 18 - 18 \leq - 72 + 18 \\ 9k \leq - 54[/tex]
Divide both sides by 9
[tex] \frac{9k}{9} \leq - \frac{54}{9} \\ [/tex]
We have the final answer as
[tex]k \leq - 6 \\ [/tex]
Hope this helps you
