Plot \( A, B \) and \( C \) and join them up. \( \triangle A^{\prime} B^{\prime} C^{\prime} \) is the image of \( \triangle A B C \) after an enlargement by a factor of 3 . i) Sketch \( \triangle A^{\prime} B^{\prime} C^{\prime} \) and show the coondinates on the sketch. ii) Draw a rectangle around \( \triangle A^{\prime} B^{\prime} C^{\prime} \) and determine the area of \( \triangle A^{\prime} B^{\prime} C \). iii) Draw a rectangle around \( \triangle A B C \) and determine the area of \( \triangle A B C \). ivi) Show, by calculation, that the ratio of the areas is \( 1: 9 \).

Solve \( w^{2}=-9 \), where \( w \) is a real number. Simplify your answer as much as possible. If there is more than one solution, separate them with commas. If there is no solution, click on "No solution".

CUANDO HAYA COMPRENDIDO TODAS LAS INSTRUCCIONES, INICIE EL 1. Pregunta Las componentes del vector A con origen en \( (5 ;-7) \) y extremo en \( (2 ;-3) \) son:

Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system. \( \left\{\begin{array}{l}x+y=8 \\ x-y=2\end{array}\right. \) B. The solution is \( x=5 \) and \( y=3 \). (Type integers or simplified fractions.) ordered pairs, they can be expressed as \{( \( x, y) \mid x= \), \( y \) is any real number \( \} \) (Simplify your answer. Type an expression using \( y \) as the variable as nethed.) C. The system is inconsistent
