Answer:
d Dilation by a scale factor of 2 followed by reflection about the y-axis
Step-by-step explanation:
In each case, the transformation is ...
(x, y) ⇒ (-2x, 2y)
So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.
The transformations are ...
Dilation by a scale factor of 2 followed by reflection about the y-axis
4x1/2=2. 2 is less than 4 so it shows that it is false.
Answer:
180 seconds
Step-by-step explanation:
1 minute = 60 seconds
120 * 3 = 360
60 * 3 = 180
