Answer:
(C) It cannot be a translation, rotation or reflection as the figures are not congruent.
Your answer will turn out to be −4x^2+3x.
C is the correct answer because I guessed
Answer:
Top left, top right, bottom right
Step-by-step explanation:
Combine all of them together. I'll use the top left and middle left as my example. We will need to end up with 2 positive x's, 5 negative y's and the number 3.
x + x - y + 1 + 1 + 1 - y - y - y -y
We can see here there are 2 positive x's, 5 negative y's, and the number 3.
If we were to write that into an equation it would be 2x - 5y +3
With the middle left we have
-5y - x -x + 2 + 1
Here we have 2 negative x's, 5 negative y's, and the number 3.
If this were simplified it would be -2x - 5y + 3. We don't want the 2x to be negative therefore it is incorrect.
To estimate, you would usually round to a significant figure
so, 20* 70=1400
The actual answer is 1521, so we know we are close
