Answer: El otro avión recorrió a distancia de 1362.5 km.

Step-by-step explanation:

Vamos a definir:

Norte es el eje y-positivo.

Oriente (o este) es el eje x-positivo.

Y también sabemos que si tenemos los puntos (a, b) y (c, d)

La distancia entre esos puntos es:

Distancia = √( (a - c)^2 + (b - d)^2)

Ahora, uno de los aviones va hacia el norte, entonces si el aeropuerto está en la posición (0, 0), después de un rato viajando hacia el norte su nueva posición va a ser (0, A)

Mientras que el que va al oeste va a tener una nueva posición (B, 0)

La distancia entre ellos es:

Distancia = √( (B - 0)^2 + (0 - A)^2) = √( B^2 + A^2)

Sabemos que cuando la distancia entre ellos es 1580 km, uno de ellos ha recorrido 800km, asumamos que A = 800km.

Entonces tenemos la ecuación:

1580 km = √( B^2 + (800km)^2)

(1580km)^2 = B^2 + (800km)^2

(1580km)^2 - (800km)^2 = B^2

√((1580km)^2 - (800km)^2 ) = B = 1362.5 km

El otro avión recorrió a distancia de 1362.5 km.

Im not able to make a distance-time graph, since they don't have a graphing app but I've done this type of problem. 

They walked the same distance.

What is −2x−x+8 help please
MAVERICK [17]

Answer:

  -3x +8

Step-by-step explanation:

Apparently, you want to simplify the expression. That means you want to "collect terms", or "combine like terms."

"Like terms" are ones with the same variable structure. Here, the three terms in the expression are (-2x), (-x), and (+8). The ones that both have x as a variable are (-2x) and (-x). The way we combine these is to add the coefficients of the variable:

  (-2x) +(-x) = x(-2) +x(-1)

  = x(-2 -1)

  = x(-3)

  = -3x

So, the two "x" terms combine to give -3x. The constant term (+8) is not combined with anything. The simplified expression is then ...

  -3x +8

_____

<em>Additional comments about writing and combining terms</em>

When math symbols are written next to each other, it means they are multiplied. -2x means (-2) × (x). It can be written several ways, including ...

  • -2x
  • (-2)x
  • x(-2)
  • (x)(-2)
  • (-1)(2x)

Usually, the coefficient is written in front of the variable. In the above, we have chosen to write the coefficient after the variable so that the expression shows some parallelism with the usual expression of the <em>distributive property</em>:

  a(b +c) = ab +ac

  x(-2 -1) = x(-2) +x(-1)

The answer to B and C
ArbitrLikvidat [17]
Assuming that the triangles are congruent, you can just look at the parts on each triangle to find the parts on the other triangle. The answers are yes, yes, and no. The triangles are obviously not drawn to scale, so just remember to never rely on it being so.
