Question

Math help please!
|120+x| x<-120

Answer 1

-120-x

Explanation:

Given:

`\displaystyle \large`

This is the same as previous one. Recall modulus property:

`\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}`

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x
