Question 2

Find the values of x that satisfy the inequalities.  and

Accepted Answer

Subtracting 2x from both sides of the first inequality and adding 3x to both sides of the second inequality, we get:

-x <= -15 
4x >= 8

Solving for x in each inequality, we get:

x >= 15 
x >= 2

The values of x that satisfy both inequalities are those that are greater than or equal to 15 and greater than or equal to 2, which means x is greater than or equal to the larger of these two values. Therefore, the solution is x >= 15.

The only answer choice that corresponds to this solution is C.
