SpyIntel [72]

Answer:

-300.

Step-by-step explanation:

First, you'd have to subtract 1500 from 1200. This gives you 300, but since she is descending rather than ascending, the number is negative rather than positive.

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>
