Solving Compound Inequalities

Answer:

The Fourth Choice


x > -7

Please refer to the attached image for the graph

Explanation:

Given:


2x +5 > -9 \text{ or } -3x +2 < 14

Let's solve for the
2x +5 > -9 part of the Compound Inequality first.


2x +5 > -9 \\ 2x > -9 -5\\ 2x > -14 \\ x > (-14)/(2) \\ x > -7

Now, let's solve
-3x +2 < 14:


-3x +2 < 14 \\ -3x < 14 -2\\ -3x < 12 \\ x > (12)/(-3) \\ x > -4

We can now rewrite our Compound Inequality as
x > -7 \text{ or } x > -4. However, we can further simplify it by rewriting it as
x > -7 only since the values
-7 < x \leqslant -4 are already greater than
-7 anyway.
