For three consecutive years, sam invested some money at the start of the year. the first year, he invested x dollars. the second year, he invested $2,000 less than 5/2 times the amount he invested the first year. the third year, he invested $1,000 more than 1/5 of the amount he invested the first year. during the same three years, sally also invested some money at the start of every year. the first year, she invested $1,000 less than 3/2 times the amount sam invested the first year. the second year, she invested $1,500 less than 2 times the amount sam invested the first year. the third year, she invested $1,400 more than 1/4 of the amount sam invested the first year. if sam and sally invested the same total amount at the end of three years, the amount sam invested the first year is $
and the amount sally invested the last year is $ (fill in the blanks)

The amount Sam invested the first year is $2000 and the amount Sally invested the last year is $1900.

let's add {f(x)=x+1}f(x)=x+1 and {g(x)=2x}g(x)=2x together to make a new function.

f(x)+g(x) =(x+1)+(2x)=x+1+2x=3x+1

let's call this new function hh. so we have:

{h(x)}={f(x)}+{g(x)}{=3x+1}h(x)=f(x)+g(x)=3x+1

we can also evaluate combined functions for particular inputs. let's evaluate function hh above for x=2x=2. below are two ways of doing this.

method 1: substitute x=2x=2 into the combined function hh.

h(x)

h(2)

​    

=3x+1

=3(2)+1

=7

​ since h(x)=f(x)+g(x)h(x)=f(x)+g(x), we can also find h(2)h(2) by finding f(2) +g(2)f(2)+g(2).

first, let's find f(2)f(2):

f(x)

f(2)

​    

=x+1

=2+1

=3

​  

now, let's find g(2)g(2):

g(x)

g(2)

​    

=2x

=2⋅2

=4

​  

so f(2)+g(2)=3+4=\greend7f(2)+g(2)=3+4=7.

notice that substituting x =2x=2 directly into function hh and finding f(2) + g(2)f(2)+g(2) gave us the same answer!

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies
