Dentro de 5 años mi edad será igual a la edad que tú tienes actualmente y al sumar nuestras edades en ese entionces obtendria 55 años. ¿Cuál es mi edad? a. 40 años

The number of incarcerated adults N (measured in thousands) in a certain country can be approximated by the equation \( \mathrm{N}=-2.8 \mathrm{x}^{2}+72.4 \mathrm{x}+1914 \), where x is the number of years since 2000. In 2012 , the number of incarcerated adults peaked. How many adults were incarcerated in that year? There were \( \square \) incarcerated adults in 2012.

VERTICAL A. \( 3 X+2=32 \)

4. \( 4 x-2 x+2=2 x-2-2 x \)

Given the quadratic \( y=-2(x+1)^{2}-7 \) write the equation in standard form.

a) \( 2 / 6=9 / x \) b) \( 1 / 3=x / 12 \) c) \( x / 10=6 / 5 \) d) \( \delta / x=2 / 15 \)
