I think it’s -2.8
hope this helps :)
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)
Answer:
So option b is right.
Step-by-step explanation:
Given that a figure is located in Quadrant I.
The figure is transformed and the image is located in quadrant iv.
We have to select the option which would have resulted in this.
A) rotating 360 degrees would result in the same place i.e. I quadrant hence wrong.
B) rotating 180 degrees counterclockwise, will make y coordinate negative but x coordinate will remain as it is.
Hence we get image in the IV quadrant.
THis option is correct
C) Rotating90 degrees counterclockwise will not transform all the coordinates to the IV quadrant hence wrong
D) Rotating 270 degrees counterclockwise would make the image in III quadrant hence wrong
So option b is right.
2×6×15=180
Step-by-step explanation:
2×6=12
12×15=180
Assuming the speed is in miles per hour, simply divide the total distance by time.
515.97/6.5
The answer is 79.38 miles per hour
