Question

A certain region is losing about 11 million acres of rainforest each year. Find the linear function that calculates the changes in acres of rain forest in million of x years. Find f(5) and intercept the results

Answer 1

let x be number of years..
Y = be total remaining area..

So Y = Y(x-1) -11(x)...

what say ??

Answer 2

for x = 5..

y = y (5-1) - 11(5)
y = 5y - 5 - 55
4y = 60

y = 15 Million acers.. does that make sense ??

Answer 3

Yes it does. I just didn't know where to plug in which number

Answer 4

So over 5 years then they would lose 15 million acres?

Answer 5

actually if they lose 11 million per year an after 5 years the 15 million does not make since.

Answer 6

f(x) = x ....Where does the 11 fit in.

Answer 7

so we use f(5). I know x equals 5 so on both sides x is replaced with the 5

Answer 8

yes.. what i tried to figure out is, amount of ground remaining :-p.. thats also vague..

Answer 9

simple w0uld be y = 11x,

x = 5


so, y = 11 (5) = 55 acres,...

Answer 10

I was think of something like f(5)=x-11...but I don't know what goes in front of the x to multiply by

Answer 11

Okay so it would be represented by f(5)=11x

Answer 12

no no.. x is number of months and it says 11acres per month...

Answer 13

it was simple, i was trying to complicate.. sorry for that

Answer 14

about 11 million acres per year

Answer 15

per year would be represented by a 1

Answer 16

and I am trying to find out with the use of f(x) over how many years and how many acres in that amount of time would disappear

Answer 17

ya , the same and x is also number of years...

sorry, TYPO error..

Answer 18

Okay I think I have it. So it would be f(5)=11x
f(5)=11(5)
f(5)=55

Answer 19

uggg...its to late to be doing this but it's do today.

Answer 20

are you good with graphing.

Answer 21

This next one has me boggled it gives me no pass through point.
