The number of mold cells doubles every 12 minutes. At this moment, there are x mold cells present on a piece of bread. Which of the following represents the number of mold cells present one hour from now?

Step-by-step explanation:

Suppose that at time we have x mold cells. We are told that after 12 minutes the amount present is double. That is a we have 2x cells. Then, at we have (2x)*2 = 4x. We can continue as follows

we have (4x)*2 = 8x.

we have (8x)*2 = 16x

(one hour later) we have (16x)*2 = 32x.

So after one hour from now we have 32x cells.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m
