Question

What does the graph of 4 < n + 6 < 9 look like?

Answer 1

It looks like a number line. What do you think it looks like?

Answer 2

To find out, work the problem out.

4 < n + 6 < 9





First break it down into two parts since we have two inequalities

(1) n + 6 < 9
(2) n + 6 > 4

(1) n + 6 < 9
n < 9 - 6
n < 3


(2) n + 6 > 4
n > 4 - 6
n > - 2

So n is greater than - 2 but less than 3

How would you draw the number line?
