De acuerdo con la siguiente función f(x)=-3x+8, ¿cuál es el punto de intersección de su grafica con el eje y?
Ket [755]

Answer:

El punto de intersección con el eje “y” será (0 ; 8).

Step-by-step explanation:

En este caso la función es f(x)= -3*x + 8, o lo que es lo mismo, y= -3*x + 8

Para encontrar la intersección en y, se debe sustituir a la variable x por 0 por en la función. Una vez hecha la sustitución, es posible resolver la ecuación para encontrar el valor de y.

En este caso:

y= -3*0 + 8

Resolviendo:

y= 0 + 8

y= 8

Otra forma de resolverlo es, siendo la función f(x)= m*x + b (donde m es la pendiente y b la ordenada al origen), el valor b es el punto donde una recta cruza el eje y. En este caso la ordenada al origen tiene un valor de 8.

Entonces <u><em>el punto de intersección con el eje “y” será (0 ; 8).</em></u>

slavikrds [6]
6hrs = school
9hrs = sleeps              = 18hrs // 24hrs      ----6hrs left
3hrs = plays

6hrs = other things


playing = 12.5% -- 3/24                 3/24*100
other things = 25% -- 6/24             6/24*100

Answer:

  d  Dilation by a scale factor of 2 followed by reflection about the y-axis

Step-by-step explanation:

In each case, the transformation is ...

  (x, y) ⇒ (-2x, 2y)

So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.

The transformations are ...

  Dilation by a scale factor of 2 followed by reflection about the y-axis
