Question

-5 <9g + 22<4
........................

Answer 1

D

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

-3 ≤ g ≤ -2

Answer 2

Good morning

Answer:

D.

Explanation:

let’s try to solve this compound inequality:

-5 ≤ 9g + 22 ≤ 4

⇔

-5 - 22 ≤ 9g ≤ 4 - 22

⇔

-27 ≤ 9g ≤ -18

⇔

`(-27)/(9) \leq x\leq (-18)/(9)`

⇔

`-3\leq x\leq -2`

which is the set described in option D
