Juana compró una camioneta 4x4 a S/ 42 000; además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal duran

te 6 años. Si al quinto año la camioneta tendrá un valor de S/ 21 000, ¿cuál es el valor de la depreciación de la camioneta?

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año

Answer:

The three points lie on a straight line

A line through the points passes through the origin

The graph shows a proportional relationship

Step-by-step explanation:

Given statements:

a) The three points do not lie on a straight line.

b) The three points lie on a straight line.

c) A line through the points passes through the origin.

d) A line through the points does not pass through the origin.

e) The graph shows a proportional relationship.

f) The graph does not show a proportional relationship.

For the first and second statements, we can see that the points are able to be connected with a straight, diagonal line (see attached graph). This makes statement a false, and statement b true.

a = false

b = true

For the third and fourth statements, we can see that on the attached (revised) graph on my answer, that the line can continue and pass through the origin, or (0,0). This means that statement c is true, and statement d is false.

c = true

d = false

For the fifth and sixth statements, we know that a relationship is proportional if it is a straight line and passes through the origin when graphed. We have already concluded above that both of these are true, so this means that the graph does represent a proportional relationship. This means that statement e is true, and statement f is false.

e = true

f = false

From the above work, we can conclude that the following statements are true:

b (The three points lie on a straight line)

c (A line through the points passes through the origin)

e (The graph shows a proportional relationship)

Hope this helps :)

3x – 4(x - 4) + 4 = 13<br> Solve for x step by step <br> Please answer quickly
dmitriy555 [2]

Answer:

7

Step-by-step explanation:

3x – 4(x - 4) + 4 = 13

=> 3x - 4x + 16 + 4 = 13

=> - x + 20 = 13

=> - x = 13 - 20

=> - x = - 7

=> x = 7

The temperature at 12:00 p.m. was 8°C. At 7:00 p.m., the temperature was -6°C. What was the change in temperature (in degrees Ce
Alik [6]

Answer: 14-degree decrease

Step-by-step explanation:

because it is getting colder and we know this because anytime temperature goes from positive to negative it becomes mad cold.

Anyways subtracting 14 from our initial temp at 8 degrees celsius brings us to a brisk -6 celsius
