On a coordinate plane, triangle A has points (negative 2, 0), (negative 6, 0), (negative 4, 4). Triangle A prime has points (1,
0), (3, 0), (2, negative 2).
Which describes the sequence of transformations used to obtain the image (triangle A’) from the pre-image (triangle A)?
dilation by a scale factor of 2, then rotation of 180° about the origin
dilation by a scale factor of 2, then a reflection over the x-axis
dilation by a scale factor of 1/2, then a rotation of 180° about the origin
dilation by a scale factor of 1/2. then a reflection over the x-axis

<u>Given</u>:
Given that Jasmine rides her bike 9 miles in 50 minutes.
We need to determine the speed per hour.
<u>Time per hour:</u>
The time taken is 50 minutes. We need to convert minutes into hours.
Thus, we have;
Thus, the time taken to cover 9 miles is
<u>Speed:</u>
The speed can be determined using the formula,
Substituting the values, we have;
Simplifying, we get;
Thus, Jasmine's speed is 10.8 miles per hour.
