I have attached an image of the question

Answer:

-10 , -5 , 0 and 5

Step-by-step explanation:
The given inequality is:
-3x + 5.9 ≥ -15.4

We will need to isolate the x on one side of the inequality as follows:
First, we will subtract 5.9 from both sides of the inequality as follows:
-3x + 5.9 - 5.9 ≥ -15.4 - 5.9
-3x ≥ -21.3

Then, we will divide both sides of the inequality by -3. Remember that when we divide by a negative number, we flip the inequality sign as follows:
-3x / -3 ≥ -21.3 / -3
x ≤ 7.4

This means that x could be any value starting from -
∞ till 7.4
The given set is (-10,-5, 0, 5, 10)
Now, we will check the given options, the correct ones would be those having a value of 7.4 or less.
This means that the correct options are:
-10 , -5 , 0 and 5

Hope this helps :)
