None of these really do. The associative property is about regrouping things being added, such as
   (3+5)+7 = 3+(5+7)

Someone could I guess argue the “4+2y+7x+8” used it, by dropping the parentheses and thereby changing the grouping to just be the standard left-to-right that the order of operations dictates. But that’s a pretty lame answer if that’s what the person is going for.

What are the coordinates of the image of point L(4, 2) after a reflection over the line y = –1?
andrey2020 [161]

Answer:

  L'(4, -4)

Step-by-step explanation:

When you're given a midpoint, you can find the point equidistant on the other side of the midpoint by subtracting the relevant coordinate from <em>double that of the midpoint</em>.

Here, the line of reflection is the horizontal line y=-1, so you know only the y-coordinate will change. The reflected point will be ...

  (x, y) ⇒ (x, -2-y)

so the point of interest is ...

  L' = (4, -2-2) = (4, -4)

Greenland, the largest island in the world, is 21 times larger than Iceland. The combined area of Greenland and Iceland is 880,0
Vlad1618 [11]
Greenland is x
Iceland is g

g + x = 880,000   
x = 21g

Solve both equations for x (Greenland)
x = 880,000 - g
x = 21g

Because of the transitive property, which states that <span>for any real numbers a, b, and c: If a = b and b = c, then a = c, you can set the two things that equal x equal to each other.
21g = 880,000 - g

Then you simplify.
21g = 880,000 - g
21g + g = 880,000 -g +g
22g = 880,000</span>
