Question

How do you graph and solve `|1+x|<8`?

Answer 1

`-9 < x < 7`

We can graph this on a number line by placing hollow dots over `-9, 7` (to indicate they are not part of the solution) and connecting the two dots with a line segment.

Explanation:

We can approach this question this way:

`abs(1+x)<8`

`-8<1+x<8`

`-9 < x < 7`

We can graph this on a number line by placing hollow dots over `-9, 7` (to indicate they are not part of the solution) and connecting the two dots with a line segment.
