The distance, in feet, two boys travel per second on a treadmill is shown to the left. Which comparison is accurate? Xavier is traveling at 1.5 feet per second.
Moises is going faster than Xavier.
The difference in their rates of change is 1 foot per second.
If both boys remain on the treadmill for 10 minutes, Xavier will have traveled a greater distance.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

15.36 per mile

but forgot to round

i am pretty sure

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
