19. La distancia de frenado de un auto en ciertas condiciones es directamente proporcionalidad a la velocidad del auto. Si la distancia de frenado de un auto que conduce a \( 40 \mathrm{~km} / \mathrm{h} \) es de 50 metros, ¿cuấ sería su distancia de frenado si conduce a \( 100 \mathrm{~km} / \mathrm{h} \) ? A) 20 metros B) 75 metros C) 125 metros D) 150 metros

Define el logaritmo de \( 1000 \) en base 10.

8. Ironman can fly at the constant rate of 2.682 kilometers per second. He leaves the Stark tower and flies to the Moon, which is 961,000 miles away, at the same speed. Approximately, how many hours after take-off does Iromman reach the Moon? ( 1 mile \( =1.6 \) kilometers). A. 1.43 B. 40 C. 100 D. 159

The graph of \( y=|x-3|+2 \) is reflected across the \( y \)-axis and then translated down two units. What is the equation of the transformed graph? ( \( y=|-x+3|-2 \) \( \begin{array}{l}y=|x+3| \\ y=|-x+3| \\ y=-|x+3|+4\end{array} \)

Find the slope for the points (0, 0) and (4, 8).
