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).

Is -7,964,837 × -7 positive or negative?
Inessa05 [86]
When using both negative symbols, and then multiplying them, this would mean that the numbers would be going up. 

A negative (x's) a negative equals a positive.

Your answer: positive.

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits
Sati [7]

Answer:

Step-by-step explanation:

The<em> theoretical </em>frequency would be 1/4, and if spun 60 times, 15/60.

The <em>relative</em> frequency is how many times it <em>actually</em> landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20

Please let me know if you have questions, or if it's marking these answers wrong.

Write an equation that represents the line
Dafna11 [192]

Answer:

y = -4/3x -1

Step-by-step explanation:

y = slopex + y-int

We can find the slope -4/3 by going down 4 times to the level of the second point from the first point. Then we go to the right 3 times to get to the 2nd point.

y = -4/3x + b

The spot on the line where x is 0 will be the y-intercept

In this case it is -1

y = -4/3x - 1
