About 60,000 acres of wetlands are lost each year in the United states. What integer represents the change in wetlands after 4 y
QveST [7]

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.

Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (
Minchanka [31]

Answer:

C

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means -\sqrt{x}

the vertex is usually at (0,0), now how do we move a graph?  or in other words  translating it.

To move left and right you use \sqrt{x-h} where if you subtract h you move right and if you add h you move left.  we go from (0,0) to (-4,2).  so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use \sqrt{x}+v Here if v is positive you move up and if v is negative you move down.  going from (0,0) to (-4,2) it moves up 2

So now we put them all together -\sqrt{x+4}+2  And if you look, C matches that exactly.
