Are you sure you wrote that equation right
The temperature decreased so you would subtract the amount from the original temperature.
The answer would be:
-15 - 10 = -25
Answer:
D
Step-by-step explanation:
When reflecting across the Y axis, the Y values remain the same.
Now if you were reflecting across Y = 0, the x values would just be inverse ( opposite signs).
So this triangle if reflected across Y = 0 the new vertices would be (4,4) (2,3) and (5,2)
Now since the reflection line is y = -1, which is a one unit shift to the left of y = 0, subtract 1 unit from each X value.
The locations are now: A'(3,4), B'(1,3) and C'(4,2)
The correct answer is x=5
