Answer:

y=-3x+4

Step-by-step explanation:

In function notation we have y in one side and the x (like free variable) and other numbers in the other side.

9x+3y=12

3y=12-9x

3y=-9x+12

y=(-9x+12)/3

y=-3x+4

the function is : f(x) = -3x+4

Step-by-step explanation:

hello :

9x + 3y = 12   calculate y :     3y = -9x+12

divid by : 3        y = -3x+4

the function is : f(x) = -3x+4

en un colegio mixto hay x estudiantes distribuidos en c cursos. Si hay m niños por curso, ¿Cuantas niñas hay en el colegio?
Tomtit [17]

La ecuación que nos dice cuantas niñas hay en el colegio es:

A = x - c*m

¿Como encontrar una expresión para la cantidad de niñas?

Sabemos que hay un total de x estudiantes, definimos las variables:

  • A = cantidad total de niñas
  • B = cantidad total de niños.

Entonces tenemos A + B = x

Tambien sabemos que los estudiantes estan divididos en c cursos, de tal forma que hay m niños por curso.

Entonces c por m es igual a la cantidad total de niños:

c*m = B

Reemplazando esto en la ecuación de arriba podemos obtener:

A + c*m = x

A = x - c*m

Esta es la ecuación que nos da el numero total de niñas en el colegio.
