Question

What is the answer to this? And where and what direction do I shade to?

-12<-2n

<--------------------------------------------->
3 4 5 6 7 8 9 10 11 12 13

Answer 1

n<6, see image, shade to the left

Explanation:

Divide both sides by -2.

If you divide be a negative, you must reverse the inequality symbol.

You can see that the inequality symbol is "pointing" at the n. I just turned it back around again bc it's easier to read that way. It is still "pointing" at the n, so it means the same thing. It says, "n is less than 6" What numbers are less than 6? Like 5, 4, 3, etc. Even 5.25 and 5.9 are less than 6. So put an open circle on the 6 (some classes/teachers/books put a parenthesis instead of an open circle, face it towards the shading) Then shade to the left. See image.

Answer 2

n<6 is the answer so probably shade the 6 area. I don't really know where to shade but do know that n<6 is the answer.
