\frac{70}{1,8} \approx 38.8  \ \ \ \  \ \rightarrow \ the \ amount \ of \  time \ to \ double \ the \ consumption \\ \\
38,8 - 100\% \\ 6 - x \\
38,8 x = 600\% \\x \approx 15.5\% \\ \\
In \ six \ years \ oil \ consumption \ will \ increase \ by \ approximately \ 15.5\%

How do u solve two points using the distance formula?
aliya0001 [1]

Step-by-step explanation:

For two points (x₁, y₁) and (x₂, y₂), the distance between them is:

d² = (x₁ − x₂)² + (y₁ − y₂)²

The order of points 1 and 2 don't matter.  You can switch it:

d² = (x₂ − x₁)² + (y₂ − y₁)²

This is basically the Pythagorean theorem for a coordinate system.

Let's do an example.  If you have points (1, 2) and (4, 6), then the distance between them is:

d² = (4 − 1)² + (6 − 2)²

d² = 3² + 4²

d² = 9 + 16

d² = 25

d = 5

If you have points with negative coordinates, remember that subtracting a negative is the same as adding a positive.

For example, the distance between (-1, -2) and (4, 10) is:

d² = (4 − (-1))² + (10 − (-2))²

d² = (4 + 1)² + (10 + 2)²

d² = 5² + 12²

d² = 25 + 144

d² = 169

d = 13

How can graphs on the coordinate plane represent proportional relationships
bulgar [2K]

Answer:

Step-by-step explanation:

  • La gráfica de una función de proporcionalidad directa es una recta que pasa por el origen de coordenadas.
  • En consecuencia, para representarla sólo necesitamos un punto y el origen, los cuales uniremos mediante una línea recta. Para obtener dicho punto usaremos la ecuación.

Dilate the figure by the scale factor. Then enter
Nina [5.8K]

The triangle ABC was dilated with a scale factor of 5 to form a figure with new coordinates at A'(-15, -5), B'(10, -10) and C'(-5, -20).

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> reflection, translation, rotation and dilation.</em>
