A rock climber begins climbing at an altitude of 120 meters. She climbs at a rate of 25 meters per hour. Which equation could be used to fi nd the altitude of the rock climber, y, after x hours?

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

"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.
