Answer 1

-6<x<-9

Explanation:

if x+9<0 and 2x>-12

x<-9

x>-6

X is smaller than -9 but greater than -6.

The solution is -6<x<-9

Answer 2

C: x > -6 or x < –9

Explanation:

x + 9 < 0 or 2x > –12

For x + 9 < 0:

Isolate x by subtracting 9 from both sides of the inequality:

x + 9 – 9 < 0 – 9

x + 0 < – 9

x < – 9

For 2x > – 12:

Isolate x by dividing both sides of the inequality by 2:

`(2x)/(2) > (-12)/(2)`

x > – 6

Therefore, the solution is:

x < – 9 or x > – 6

Interval notation: [(– ∞, –9) ∪ (–6, ∞)]

The answer is C: x > -6 or x < –9
