Question

Write as an inequality 9 is greater than or equal to w, and -7 is less than or equal to w

Answer 1

"9 is greater than or equal to w" translates to
`9 \ge w` which flips to
`w \le 9`. We swap both sides and flip the inequality sign as well.

"-7 is less than or equal to w" translates to
`-7 \le w`

We have
`-7 \le w` and
`w \le 9` which then ultimately combine into the compound inequality
`-7 \le w \le 9`

Final Answer:
`-7 \le w \le 9`

Answer 2

`9 \geqslant w \\ \\ - 7 \leqslant w`
