Which value or values for the variable x from the set below will make 4.5 + 1.2x ≥ 10 - x true? {3, 4, 5, 6} 1. only 3
2. 3 and 4
3. 3,4, and 5
4. all values in the set

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

Option 4 is correct option.
