Write the coordinates for the given dilation
kenny6666 [7]

<u>Answer:</u>

D_o of Y = (-3/2, -1)

<u>Step-by-step explanation:</u>

We are given three points on the graph:

X (4, 0)

Y (3, 2)

Z (2, 2)

and the scale factor of dilation which is -\frac{1}{2}.

Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.

Y =  (-\frac{1}{2} × 3 , (-\frac{1}{2}[/tex] × 2)

Y = (-\frac{3}{2} , -1)

If possible, draw a line of symmetry in each of the following figures or words. If it is not possible to draw a line of symmetry
Marrrta [24]

Answer:

  a) none

  b) vertical through the middle

  c) horizontal through the middle

  d) none

Step-by-step explanation:

a) A repeated asymmetrical pattern rarely has a line of symmetry. (I can't think of a case where it does.)

__

b) This figure has left-right symmetry about its centerline. (In general, a light bulb will not, because the screw threads are asymmetrical.)

__

c) Each of the letters is symmetrical about its horizontal centerline, so  the word is as well.

__

d) The letter S is symmetrical about its center point, but not about any horizontal or vertical line. This word is not symmetrical about any line.

__

Function f is shown on the graph below where two points are marked. If function f is horizontally compressed by a factor of 2, p
lilavasa [31]

Answer:

If you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)

Step-by-step explanation:

If your compression is horizontal then the transformation you are making is the following

g(x)  = f(x/2)

Therefore, if you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)
