In a four-year period, about 80,000 acres of coastal wetlands in the US are lost each year. What integer represents the total change in coastal wetlands?

-80,000

Step-by-step explanation:

An integer is a whole number , can be positive or negative

Since we are talking about a loss here, then we have something being subtracted

Hence, we are expecting a negative value;

So the integer representing the total change in coastal wetlands will be -80,000

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

a is the correct
