etermine el cardinal de los siguientes conjuntos: \( J=\{2,4,4\}, K=\{2,4,6 \). \( =\{1,\{1\}\}, M=\{\{1\},\{1,1\}\} \). Es posible que \( \{a, b\}=\{a\} \) ? Si no lo es, ¿por qué no? Si lo es, ¿en qué caso o scribaso de un modo más simple los siguientes conjuntos: \( \{x: x=a\} \) y \( \{x: \) \( o x=b\} \). onsulte sobre la versión de la paradoja de Russell conocida como la paradoja arbero (o del peluquero).

1. Resuelve los siguientes sistemas de inecuacion lineales. a) \( \left\{\begin{array}{l}y \geq 3 x \\ 2 x+y<3-y\end{array}\right. \)

Natasha is constructing the bisector of \( P Q \). She has already constructed an arc as shown. What should Natasha do for her next step? Place the point of the compass on point \( Q \) and draw an arc, using the same width for the opening of the compass as the first arc. Place the point of the compass on point \( Q \) and draw an arc, using \( Q X \) as the width for the opening of the compass. Place the point of the compass on point \( X \) and draw an arc, using \( Q X \) as the width for the opening of the compass. Place the point of the compass on point \( X \) and draw an arc, using the same width for the opening of the compass as the first arc.
