Answer:
1 point. O (0,0)
Step-by-step explanation:
Hi
Invariant points are those points who remain on the same location after a given transformation.
1. Plotting OABC we have it below:
2. Whenever we dilate centered, the image O'A'B'C' will be determined by the following points:
![O'(0,0) \:A'(3,0) B'(6,6) \:and\:C'(0,6)](https://tex.z-dn.net/?f=O%27%280%2C0%29%20%5C%3AA%27%283%2C0%29%20B%27%286%2C6%29%20%5C%3Aand%5C%3AC%27%280%2C6%29)
Since the Scale factor is (2)
3. Check it out O'A'B'C' below
4. On the perimeter of O'A'B'C' (enlarged OABC) we have left 1 point invariant.
Answer:
13 Quarters
Step-by-step explanation:
Let <u>D</u> and <u>Q</u> stand for the numbers of Dimes and Quarters.
We are told that:
D + Q = 31
We also find that:
D = Q + 5
Use the second expression (for D) in place of D in the first equation:
D + Q = 31
(Q+5) + Q = 31
2Q = 26
<u>Q = 13</u>
This means there are:
D = 13 + 5 or <u>18 Dimes</u>
======================
Check
D + Q = 31 ?
18 + 13 = 31 <u> YES</u>
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>
Answer:
(5,-4)

Hii i don't know how to explain but i hope this helps
For clarification, < is less than, > is greater than, and then there is =.
A. So you have to take the percent of each number first.
50% of 20 = 0.5 x 20 = 10
40% of 30 = 0.4 x 30 = 12
Then put in the appropriate sign.
10 < 12
B. 75% of 12 = 0.75 x 12 = 9
30% of 20 = 0.3 x 20 = 6
9 > 6
