........................

Answer 1

Good morning

Answer:

D.

Step-by-step explanation:

let’s try to solve this compound inequality:

-5 ≤ 9g + 22 ≤ 4

⇔

-5 - 22 ≤ 9g ≤ 4 - 22

⇔

-27 ≤ 9g ≤ -18

⇔

$\frac{-27}{9} \leq x\leq \frac{-18}{9}$

⇔

$-3\leq x\leq -2$

which is the set described in option D

Answer 2

Answer:

D

Step-by-step explanation:

-5 ≤ 9g+22 ≤ 4

-5 ≤ 9g+22

9g+22 ≤ 4

-5-22 ≤ 9g

-27 ≤ 9g

-3 ≤ g

9g+22 ≤ 4

9g ≤ 4-22

9g ≤ -18

g ≤ -2

{g| -3 ≤ g ≤ -2}
