The first dropdown box answer is "reflection over the y axis"

See the attached image.

Note how corresponding points simply have the x coordinate negated. For example, A and M correspond
A = (2,8)
M = (-2,8)
The only difference between these two points is the x coordinate is positive for A, and negative for M

The same applies for B and N, C and O, etc etc

Whenever you negate x coordinates only, a reflection over the y axis occurs. This is the rule (x,y) ---> (-x,y)

-----------------------------------------------------------------------------------

The second dropdown box answer is the second choice

We can see this by adding 3 to the x coordinate of point M to go from -2 to 1 (-2+3 = 1). So the answer must have point V with an x coordinate of 1. The only answer choice that fits is choice 2.

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.
