Question

Which inequality has –12 in its solution set? A B C D

Answer 1

Explanation:

solve each inequality:

A : x+6<8 , x<-8-6 , x<-14

B: x+4≥-6 , x≥-10

C: x-3>-10 , x>-7

D:x≤-9

since -12 is on the left side of the number line then x≤ -9 would be the solution

Answer 2

D. x+5<-4

Explanation:

x+6<-8

x<-8-6

x<-14

x={-15,-16,-17...} No

x+4>-6

x>-6-4

x>-10

x={-10,-9,-8,-7...} No

x-3>-10

x>-10+3

x>7

x={8,9,10...} No

x+5<-4

x<-4-5

x<-9

x={-9,-10,-11,-12...} Yes.
