X+55-4
ОА
B
D​

Answer 1

D)
`x+5\leq -4`

Explanation:

We solve each of the inequalities

Option A

`x+6<-8\\x<-8-6\\x<-14`

Option B

`x+4\geq -6`

`x\geq -6-4\\x\geq-10`

Option C

`x-3>-10\\x>-10+3\\x>-7`

Option D

`x+5\leq -4`

`x\leq -4-5\\x\leq -9`

Therefore, only option D has -12 in its solution set.
