Answer: D. 2.5
Step-by-step explanation:
Given : Line segment DF is dilated from the origin to create line segment D’F’ at D' (0, 10) and F' (7.5, 5).
The original coordinates for line segment DF are D(0, 4) and F(3, 2).
We know that the scale factor(k) is the ratio of the coordinates of the image points and the original points.
Then, 
Hence, the scale factor was line segment DF dilated by = 2.5
300 miles divided by 6 hours is a rate question. So the answer would be 50 miles per hour
The answer is 15 cm. Hope I could be of help! ; )
We can do this easily using 0s.
(x - i) (x + i) (x + 4) (x - 1) = 0
If you plug in any of the numbers, you'll get 0, making the equation true.
The sum is 41.22 because first you turn all of the fractions into decimals and then it’s easier to add them all together all at once.
