QuestionSi $a \in \mathbb{X}, b \in \mathbb{R}$ y $c \in \mathbb{R}$, evalúa las proposiciones sobre $a$, $b$ y $c$.

Studdy Solution
For the fifth statement, we need to verify if the implication is true. The statement is$$(a \geq b \wedge c<0) \Rightarrow(a c \leq b c)$$This statement is true. If $a \geq b$ and $c <0$, then $ac \leq bc$. This is because when we multiply or divide inequalities by a negative number, the direction of the inequality changes.
