Express c in Inequalities: -9 < c < -1 on Number Line

Question

The expression c is a negative number greater than (-9) and less than (-1) . Write it in mathematical language and mark it on the number axis.

First, we'll mark on the number line the expression $C < 0$

Then we'll mark $C > -9$

And finally $C < -1$

Now we can see that the section marked in orange overlaps with the expressions we marked:

The numbers that create the overlapping section start from -9 to -1 and represent the requested expression:

$-9 < c < -1$

$-9 < c < -1$
