Question

write a compound inequality that represents each situations all real numbers that are greater than -8 but less than 8

Answer 1

`-8 < x < 8`

Explanation:

Your compound inequality will include two inequalities.

These are:

x > -8

x < 8

Put your lowest number first, ensuring that your sign is pointed in the correct direction.

`-8 < x`

Next, enter your higher number, again making sure that your sign is pointing in the correct direction.

`-8 < x < 8`

Answer 2

-8 < r < 8

Explanation:

Let r = real number

Greater than >

r>-8

less than <

r <8

We want a compound inequality so we combine these

-8 < r < 8
