The checked answers you have are correct.
Dilation involves changing the size of a shape.
- See attachment for the graphs of ABC, A'B'C and A"B"C"
- A"B"C" is a dilation of A'B'C', with a scale factor of 1/4
From the given diagram, we have:
<u>(a) Dilate by scale factor 2 with center (0,0)</u>
We simply multiply the coordinates of ABC by 2
So, we have:
See attachment for the graph of A'B'C'
<u>(b) Dilate by scale factor 2 with center (0,0)</u>
We simply multiply the coordinates of ABC by 1/2
So, we have:
See attachment for the graph of A"B"C'
<u>(c) Is A"B"C" a dilation of A'B'C</u>
Yes, A"B"C" is a dilation of A'B'C
- <em>ABC is dilated by 2 to get A'B'C</em>
- <em>ABC is dilated by 1/2 to get A"B"C</em>
So, the scale factor (k) from A'B'C' to A"B"C" is:
The scale factor (k) from A'B'C' to A"B"C" is 1/4
And the center is (0,0)

b (?) and c
m and n have the same slope (-2/5) so m//n
Answer:
24x+18
Step-by-step explanation:
You distribute the 6 to the 4x and the 3
Step-by-step explanation:
First count the numbers how many they are
there are 9 numbers
Then do the sum of all these numbers
<h2>9+10+6+5+69+10+6+5+6/9 </h2>
