Question

If the least value the variable k can be is 12, which of the following inequalities best shows all the possible values of k? k < 12 k > 12 k ≤ 12 k ≥ 12

Answer 1

If k must be equal to or greater than 12, it can be expressed as:

k≥12

Answer 2

The correct option is 4. The inequality k ≥ 12 shows all the possible values of k.

Explanation:

It is given that the least value the variable k can be is 12. So, the variable k can take any real value 12 or more than 12.

It means the value of k must be greater than or equal to 12. Mathematically it is can be represented as

`k\geq 12`

The inequality k ≥ 12 shows all the possible values of k.

Therefore the correct option is 4.
