Constanza usa 11/2 horas semanales por asignatura para hacer tareas, y 22/3 horas por semana para estudiar en general. Si en total dedica 36 horas para estudiar cada semana y n es el número de asignaturas que Constanza tiene, ¿Qué ecuación permite calcular el número de asignaturas que tiene Constanza?

It only took four days for her to reach $400 so if she took out the same amount of money she added each day starting after day 4, it would also only take 4 days. she would be at $0 on day 8 not 12

Use the symbol "^" to denote exponentiation.   write y = (x-9)^2 and y = (x + 9)^2.like y=x^2, the graphs of the two given functions are vertical parabolas which open upward.the graph of y=x^2 has its vertex at (0,0).   that of y = (x-9)^2 has exactly the same shape, but has its vertex at (9,0).   that of y = (x+9) has the same shape, but has its vertex at (-9,0).   the principle here is "horizontal shift."
