We are asked to write an algebraic inequality that represents following expression.
All real numbers ythat are greater than or equal to 12.
First notice that the expression greater than or equal to
can be written as ≥.
... ≥...
On the left-hand side of the inequality sign, we should write what comes before the expression greater than or equal to
. In our exercise it is y.
y ≥...
On the right-hand side, however, we should write what comes after that same expression. In our case it is 12.
y ≥ 12
