Answer:
[tex]|20-\dfrac{x}{2}|\geq 2[/tex]
Step-by-step explanation:
Half a number is at least 2 units from 20.
Let number be x
Write phrase as inequality.
"Half a number" [tex]\Rightarrow \dfrac{x}{2}[/tex]
"From 20" [tex]\Rightarrow 20-\dfrac{x}{2}[/tex]
"at least 2" [tex]\Rightarrow \geq2[/tex]
Absolute inequality:
[tex]|20-\dfrac{x}{2}|\geq 2[/tex]
Hence, The absolute value inequality is [tex]|20-\dfrac{x}{2}|\geq 2[/tex]
