well you can see that x>-7 on the graph. So A is therefore the answer.

OpenStudy (anonymous):

Thank you thank you so much!

OpenStudy (anonymous):

I have another question could you help me out?

OpenStudy (anonymous):

Solve.

OpenStudy (solomonzelman):

both sides times -3 and flip the sign s≤-18 |dw:1386729774929:dw|

OpenStudy (the_fizicx99):

-S/3 > 6 multiply both sides by -3 Because your multiplying by a negative you flip the sign. (this applies to both division and multiplication. so: s < -18 because its less than or equal to, the dot is shaded in.

Thanks. I have one more.

OpenStudy (the_fizicx99):

Yw

OpenStudy (anonymous):

Thanks all!!!

OpenStudy (anonymous):

Graph the solution set to the inequality.

OpenStudy (the_fizicx99):

Ok, same thing. what is -2 * 9 A negative + negative = positive positive + positive = positive negative + positive = negative keep in mind that when you multiply by a negative or divide you flip the sign.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

-2 • 9 = -18

OpenStudy (the_fizicx99):

Yes. Now we flip the what..?

OpenStudy (anonymous):

We flip the sign

OpenStudy (the_fizicx99):

> OR < isn't shaded in |dw:1386730325298:dw|
