Question

Javier writes an integer on a piece of paper. The absolute value of his number is less than 4. Which is true of the possible values of Javier’s number?

Answer 1

It must be less than 4 but greater than -4

Explanation:

1 - Give our unknown a variable

We'll give the integer the value x

2 - Write out the equation

| x | < 4

Because absolute value means its always positive, this means it has a range between -4 and 4 when given the rule that it must be less than and not equal to 4.

So his number x must be less than 4 but greater than -4

This is written as -4 < x < 4

Answer 2

It must be less than 4 but greater than -4

Step-by-step explanation:

1 - Give our unknown a variable

We'll give the integer the value x

2 - Write out the equation

| x | < 4

Because absolute value means its always positive, this means it has a range between -4 and 4 when given the rule that it must be less than and not equal to 4.

So his number x must be less than 4 but greater than -4

This is written as -4 < x < 4
