6. Jason is going to compete in a duathlon race, which is comprised of 15.5 miles of
biking and 6.2 miles of running. If he can bike at 3 minutes per mile, how many
minutes per mile would he need to average while running in order to complete
the race in one hour and forty minutes?

300pi

step-by-step explanation:

"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.
