The following equation represents the number of fish in a pond, f(x), after x number of weeks. f(x) = 500 (1.2)^x. at what rate is the fish population increasing or decreasing? (4.2)
a. decreasing at a rate of 1.2 fish each week.
b. decreasing at a rate of 20% each week.
c. increasing at a rate of 20% each week.
d. increasing at a rate of 1.2 fish each week.
e. increasing at a rate of 1.2% each week

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

the answer is d

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b
