8. An acidophilus culture containing 150 bacteria doubles in population every hour. The formula y = 150(2)^t can be used to model the bacteria population where y is the population of the colony t
hours after its initial population was recorded.
a. How many hours did it take for the colony to reach 1 million bacteria?
b. What will be the population of the colony after 8 hours?

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

"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.
