Scientists studied two animal populations. function f(x) = 830(0.8)x models a bear population in a given region x years after the study began. the table models the cougar population in the same region. fifteen years after the study began, about how many times greater was the cougar population than the bear population?

a.9times
b.18times
c.5times
d.2.5times

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

your answer is the frist one

hop i

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
