Which set of numbers is NOT in the solution set of the inequality x < 12?

Solution:

The given inequality is:

x < 12

Which means x is less than 12

The solution set is given as:

From this we can see, interval notation of given inequality is (-∞, 12)

Thus, numbers greater than or equal to 12 is not a solution set to given inequality

Which means,

is not a solution set to given inequality

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
