Answer:
3,-2
Step-by-step explanation:
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.
Step-by-step explanation:
2.65-2.30 is 0.35
0.35/2.65 is 0.132
0.132 X 100 is 13.2% decrease
To find a:b given 5a = 8b
From 5a = 8b
We divide both sides by 5
So we have;
a = 8b/5
Then we divide both sides by b
So we have
a/b = 8/5
Ratio of a :b = 8 : 5.
