Thank you! Great!

Thanks, CPhill! You can also complete the square, riight?

Thank you, CPhill!

Correct! Thanks!

Bringing x, and the numbers to one side, we get: \(-7-9\leq5x-3x=-16\leq2x\), so x is greater than or equal to -8. Try to see how you can form an interval.

[-8, infinity)

Thank you for a nice explanation, CPhill!

No, I don't want to do that! I want to really understand the question!

Yes, correct! Thanks!

Hint: Find the slopes of both graphs, which in this case: -1/2, 2. 

Thanks! Very good!
