That looks good to me.  What program are you using to type the math?

anonymous · Answer

I don't know the answer to the first one...

anonymous · Answer

& I printed scree and took it into paint on my pc

anonymous · Answer

Hey, Chunger. With inequalities like that, you can solve them for x almost exactly the same way you would solve an equation. The ONLY tiny difference is that if you multiply/divide both sides by a negative number, you have to switch the direction the arrow points.

anonymous · Answer

So, for the inequality
$$5x+7 \ge 2$$
Let me see you try to solve that for x.
$$\text{(You can type >= instead of } \ge \text{ and <= instead of } \le$$

anonymous · Answer

IS it the first choice? I just worked it out

anonymous · Answer

hold on I'll type it..

anonymous · Answer

After you solved the two inequalities for x, what did you get?

anonymous · Answer

x > -1 and x <= 3

anonymous · Answer

x>= -1, but yes =)

anonymous · Answer

Oh my bad, but thank you so much! (:

anonymous · Answer

And does that match the way the number line is shaded?

anonymous · Answer

yes

anonymous · Answer

Excellent! =D

anonymous · Answer

And by the way, for question 5, you did that perfectly. When you divided both sides by (-3), you switched > to <. Great job. c-:
