<span>Rotations are rigid transformations, which means they preserve the size, length, shape, and angle measures of the figure. However, the orientation is not preserved. Line segments connecting the center of rotation to a point on the pre-image and the corresponding point on the image have equal length. The line segments connecting corresponding vertices are not parallel.</span>

A rotation is a rigid transformation, sometimes called an isometric transformation, that moves every point of the pre-image through an angle of rotation about the center of rotation to create an image. Rotations preserve size, rotations of 360 map a figure to itself, and lines connecting the center of rotation to the pre-image and the corresponding point on the image have equal length.

#7. What are the values/ how do I do it
Tasya [4]

Answer:

x =2

SK = 21

KY = 13

SY = 34

Step-by-step explanation:

we can see from the picture the following:

SK + KY = SY  equation 1

SK=13x-5    equation 2

KY = 2x+9    equation 3

SY = 36-x     equation 4

using equation 2, equation 3 and equation 4 in equation 1 we have:

13x - 5 +  2x + 9 = 36-x  

15x +4 = 36 - x

15x +x = 36-4

16x = 32

x = 32/16

x= 2

using x as 2 we evaluate it in equation 2, equation 3 and equation 4:

SK=13(2)-5 = 21

KY= 2(2) +9 = 13

SY = 36-2 = 34

Helpppp now please helpppp

The correct answer is:  [B]:  " \frac{(-3)(4)}{(6)} " . 
__________________________________________________________
Consider choice [A]:  \frac{(3)(4)}{(6)} ; 
                              = \frac{12}{6} ; 
                              = 2 ;  "2 ≠ -2" ; so we can rule out:  "Choice [A]" .
__________________________________________________________
Consider choice [B]:  \frac{(-3)(4)}{(6)} ; 
                              = \frac{-12}{6} ; 
                              =  "-2" ;  Yes!
→ Let us proceed with the final answer choice ;
__________________________________________________________
Consider choice [C]:  \frac{(-3)(-4)}{(6)} ; 
                              = \frac{12}{6} ; 
                              = 2 ;  "2 ≠ -2" ; so we can rule out:  "Choice [C]" .
__________________________________________________________
The correct answer is:  [B]:  " \frac{(-3)(4)}{(6)} "  .

What is D and R? Please answer I need help.
Setler79 [48]

Answer:

  31. D: {8, 4, 0, -4}; R: {2, -1}; yes

  32. D: {-1, 2, 7}; R: {-4, -3, -2, 0}; no

  33. D: {-4, -3, -1, 2, 3, 5}; R: {-3, -2, 0, 3, 5}; yes

  34. D: (-∞, ∞); R: (-∞, 4]; yes

  35. D: [0, 5]; R: [-2, 3]; no

Step-by-step explanation:

In this context, D means "domain" and R means "range." The domain of a function is the list of input values for which the function is defined. For ordered pairs, it is the first number of the pair. For an x-y table, it is the list of x-values. For a graph, it is the possible values of x.

A relation is a <em>function</em> only if there are no repeated values in the domain (2 or more outputs for the same input.)

The range of a function is the list of output values produced by the function. For ordered pairs, it is the second number of the pair. For an x-y table, it is the list of y-values. For a graph, it is the possible values of y.

__

31. D: {8, 4, 0, -4}

    R: {2, -1}

Function: yes

Domain and range values don't need to be repeated. Often, they're listed in order from lowest to highest. Here, we have listed them in order of occurrence in the function definition.

__

32. D: {-1, 2, 7}

      R: {-4, -3, -2, 0}

Function: no

__

33. D: {-4, -3, -1, 2, 3, 5}

     R: {-3, -2, 0, 3, 5}

Function: yes

__

34. D: (-∞, ∞)

     R: (-∞, 4]

Function: yes

__

35. D: [0, 5]

     R: [-2, 3]

Function: no . . . . . . there are 2 y-values for most x-values
