Answer:
- 3. line y=x
- 4. 10 units to the right and 4 units up
Step-by-step explanation:
In the attached diagram, the green polygon A"B"C" is the reflection of ABC across the line y=x. Then the purple polygon A'B'C' is the translation of A"B"C" 10 units to the right and 4 units up.
_____
You can tell a reflection is involved, because the clockwise order of A, B, C in the original is reversed to counterclockwise in A'B'C'. The left-right horizontal line AC becomes the down-up vertical line A'C', so you know the reflection is across the line y=x, and not the line y=-x.
After the reflection, point A" is located at (2, -6), so moving it to A'(12, -2) entails a translation 10 units right and 4 units up.
Answer:
D - (-2)^2 does not equal to -4
Step-by-step explanation:
√-4 does not equal -2 because if you try squaring -2 you will get 4 not -4, because 2 negative number makes it a positive.
For example
-2 x -2 - There are two negative numbers, so it should equal...

Answer:
Step-by-step explanation:
Since x=-4 plug in the -4 into the equation to find y,
-5(-4)-4y=16
20-4y=16 -20 -20 __________
-4y=-4
-4y/-4=-4/-4
___________
y=1
So now you found both x and y so plug in both now to check if both are correct.
-5(-4)-4(1)=16
20-4=16
16=16
So both y and x are correct.
Hope this helps!:)
