Use the distributive property to remove the parentheses.
ludmilkaskok [199]

Answer:

12-6u

Step-by-step explanation:

To remove the parenthesis, we must multiply the number on the outside to each value within the parenthesis

This means that

6(2-u)\\\\6*2-6*u\\\\12-6u

Suppose you have entered 79​-mile biathlon that consists of a run and a bicycle race. During your​ run, your average velocity is
kirza4 [7]

Answer:

The distance of the run is 10 miles

The distance of the bicycle race is 69 miles

Step-by-step explanation:

Let:

  • r = the distance for the run
  • 79 - r = the distance for the bicycle race
  • t = the time of the run
  • 5 - t = the time of the bicycle race

The run: r = 5t

The bicycle race: 79 - r = 23(5 - t)

Simplify the bicycle race:

  • 79 - r = 115 - 23t
  • -r = 36 - 23t
  • r = 23t - 36

Now we have two equations set up for r

  • r = 5t
  • r = 23t - 36

We know that r = r, so 5t must equal 23t - 36

  • 5t = 23t - 36
  • 5t + 36 = 23t
  • 36 = 18t
  • t = 2

Now we know that the run took 2 hours.

Plug it back into the equation for the run to find the distance for the run

  • r = 5t
  • r = 5(2)
  • r = 10

The run is 10 miles

To solve for the bicycle race, we simply subtract 10 from 79, because we know that the two distances combined are 79.

  • 79 - 10 = 69

The bicycle race is 69 miles.

URGENT! if ABCD is dilated by a factor of 2, the coordinate of A' would be:
koban [17]

After dilating the quadrilateral ABCD by a factor of 2 and with respect to the origin, the point A(x, y) = (-3, -1) is transformed into the point A'(x, y) = (-9, -3).

<h3>How to determine the coordinates of an image after applying a rigid transformation</h3>

First of all, dilation is a type of <em>rigid</em> transformation. <em>Rigid</em> transformations are transformations applied on <em>geometric</em> loci such that the <em>Euclidean</em> distance at every point of the construction is conserved. Vectorially speaking, the dilation is expressed by the following formula:

A'(x, y) = A(x, y) + k · [A(x, y) - O(x, y)]     (1)

Where:

  • A(x, y) - Original point
  • O(x, y) - Center of dilation
  • A'(x, y) - Resulting point
  • k - Dilation factor

If we know that A(x, y) = (-3, -1), k = 2 and O(x, y) = (0, 0), then the coordinates of A' are:

A'(x, y) = (-3, -1) + 2 · [(-3, -1) - (0, 0)]

A'(x, y) = (-3, -1) + (-6, -2)

A'(x, y) = (-9, -3)

After dilating the quadrilateral ABCD by a factor of 2 and with respect to the origin, the point A(x, y) = (-3, -1) is transformed into the point A'(x, y) = (-9, -3).
