About 60,000 acres of wetlands are lost each year in the united states. what integer represents the change in wetlands after 4 years?

Over 4 years, there will be a loss of 60,000 acres per year, so 60,000 times 4 is equal to 240,000 acres. 240,000 is positive because the problem asks for the change, not the increase.

This is the work you will show

c=-60,000(4)

c=-240,000

So -240,000 represents the change.

You could also just count by -60,000 four times.

-60,000-60,000-60,000-60,000=-240,000.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
