Option 4 is correct option.
Step-by-step explanation:
We need to find the value for the variable x from the set {3,4,5,6} below will make
true
First we solve the inequality to find values for x
Adding x on both sides
Subtracting 4.5 from both sides
Divide both sides by 2.5
So, after solving inequality we get x ≥ 2.2
So, all values greater than 2.2 can be considered true. In the set given {3,4,5,6} all values are greater than 2.2 so all values in the set are considered true for![4.5 + 1.2x \geq 10 - x](/tpl/images/0923/0197/c5cd9.png)
Option 4 is correct option.
