Question 125919: Solve each compound inequality. Graph solutions set and write in interval notation.
x + 4 < 0 or 6x > -12

Okay, I just need to know where to start, because the rule is if there are two inequality signs separated by “or ” (as above) to solve for x in middle and the term “or” also means “union”. What I’m asking is what numbers do I begin with and how do I enter them? The first step to solving?
Thank you!

Simply solve each inequality individually and the final solution will be the union of these two solutions

x+%2B+4+%3C+0} Start with the first inequality


x%3C0-4Subtract 4 from both sides


x%3C-4 Combine like terms on the right side



So the first part of our answer is x%3C-4







6x+%3E+-12} Start with the second inequality



x%3E%28-12%29%2F%286%29 Divide both sides by 6 to isolate x



x%3E-2 Divide



So the second part of the answer is x%3E-2

Answer:

So together the solution is

x%3C-4 or x%3E-2



So the solution in interval notation is






Now let's graph the solution set
