C is correct

Step-by-step explanation:

Firstly, we have to solve for x in the solution set of the inequality

We have this as follows;

x + 2 ≥ 6

x ≥ 6-2

x ≥ 4

To graph this, we consider the middle sign which is greater than or equal to

So, the inequality sign has to face the right side

secondly, it has to be shaded on the point 4 due to the fact that it has the ‘equal to’ beneath the single inequality symbol

so, the correct answer here is option C

Hi there!

Shop 1.
12 pens equals $9.00
1 pen equals $9.00 / 12 = $0.75
120 pens equals $0.75 × 120 = $90.00

Shop 2.
10 pens equals $7.80
1 pen equals $7.80 / 10 = $0.78
120 pens equals $0.78 × 120 = $93.60

Therefore shop 1 is the cheapest shop and offers the best deal. When buying 120 pens the second shop is $3.60 more expensive.
