Question

Which inequality has –12 in its solution set?

a. X+6<-8
b. X+4>)-6
c. X-3>-0
d. X+5<)-4

Answer 1

D
x=-12 so
-12+5=-7
-7 is less than -4

Answer 2

option d

Explanation:

Solve each inequality and check which inequality has -12 as a solution

a.
`x+6<-8`

Subtract 6 from both sides

`x<-14`

b.
`x+4>-6`

Subtract 4 from both sides of the inequality to get x alone

`x>-10`

c.
`x-3>-0`

Add 3 on both sides

x>3

d.
`x+5<-4`

Subtract 5 from both sides

x<-9

-12 lies below -9. So x<-9 has -12 in its solution
