\frac{13[tex] \frac{100x}{100x} = \frac{1196}{100x}}{100} = \frac{x}{92} [/tex]   

you would cross multiply top left to bottom right.
then you would do same to bottom left to top right.
then you would divide number by number and variable.
in the end you would get you answer. 
may be confusing but it works.

<span>First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. if its negative then it's a percentage decrease</span>

RSB [31]
S = ut + (1/2)a(t²)                            Subtract ut from both sides
(1/2)a(t²) = S - ut                            Multiply both sides by 2
a(t²) = 2s - 2ut                                Divide both sides by t²
a= 2s/t² - 2u/t

a= (2S - 2ut)/t²

Answer is C) but there should be parentheses around the term (2S-2ut)

A. What are the coordinates of R’ if R (-2, 7) is dilated around the origin with k=3?
Sergio [31]

A: The coordinates of the point R' are (- 6, 21).

B: The coordinates of the point T' are (1, 3).

<h3>How to generate new points by definition of dilation</h3>

In this question we must make use of <em>rigid</em> transformations to find the location of new points, <em>rigid</em> transformations are transformations used in <em>geometric</em> loci such that <em>Euclidean</em> distance is conserved. In this case, we need to use a kind of <em>rigid</em> transformation known as dilation, which is defined below:

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

Where:

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

Part A - If we know that O(x, y) = (0, 0), R(x, y) = (- 2, 7) and k = 3, then the coordinates of point R' are:

R'(x, y) = (0, 0) + 3 · [(- 2, 7) - (0, 0)]

R'(x, y) = (- 6, 21)

Part B - If we know that O(x, y) = (- 2, 7), T(x, y) = (4, - 1) and k = 1/2, then the coordinates of point T' are:

T'(x, y) = (- 2, 7) + (1 / 2) · [(4, - 1) - (- 2, 7)]

T'(x, y) = (- 2, 7) + (1 / 2) · (6, - 8)

T'(x, y) = (- 2, 7) + (3, - 4)

T'(x, y) = (1, 3)
