Suppose you want to draw a rectangle where the width is 7 inches less than the length and the diagonal is 2 inches longer than t
IrinaK [193]
The diagonal of a rectangle is:
 d ^ 2 = w ^ 2 + l ^ 2
 Where,
 w: width
 l: long
 Substituting values we have:
 (l + 2) ^ 2 = (l-7) ^ 2 + l ^ 2
 Rewriting we have:
 l ^ 2 + 4l + 4 = l ^ 2 -14l + 49 + l ^ 2
 l ^ 2 -14l + 49 - 4l - 4 = 0
 l ^ 2 -18l + 45 = 0
 (l-15) (l-3) = 0
 The solutions are:
 l = 15
 l = 3
 The viable solution is:
 l = 15
 Thus, the width is:
 w = l-7
 w = 15-7
 w = 8
 Answer:
 
the dimensions of the rectangle are:
 
l = 15
 w = 8

Goshia [24]

Answer:

3.5 cookies

Step-by-step explanation:

Hi there!

7/2=3.5

So they'd each get 3.5 cookies.

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>
