the value of a number substituted for x is greater than or equal to 52

Question

what is the answer to the value greater than or equal to 52

Answer 1

The value of x is a range of values that is equal to or greater than 52.  Therefore, we write the solution like this:

 

x ≥ 52

 

This means that x can be 52, 53, 54, 55, 56, all the way to positive infinity.  You will encounter this when solving inequalities.

 

 

In interval notation, we write it like this:

 

[52, ∞)

 

The bracket means that the value is included in the solution.
