A certain area of the pond is covered in algae. Each day, the algae-covered area doubles. If it takes 24 days
for the algae to completely cover the pond, how many
days did it take to cover half of the pond?

12.

Step-by-step explanation:

it takes 24 days to completely cover the whole pond.

to cover half the pond, it takes an x amount of time (x is unknown) x is equal to the half of 24. That means 24 = 2x and x=12.

step-by-step explanation:

at least i think its

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
