Answer: Associative Property of Addition

Step-by-step explanation: The statement 7 + (4 + 4) = (7 + 4) + 4 represents the associative property of addition. Notice that the addends or the numbers we are adding are the same on both sides of the equals sign.

But on the left side, 4 and 4 are grouped together and on the right side, 7 and 4 are grouped together.

The <em>associative property of addition</em> says that when we are adding more than two numbers, the grouping of the addends does not affect the sum.

Here, the order operations tells us to begin inside the parentheses. So we have 4 + 4 which is 8 and 7 + 8 is 15.

On the right side, notice that 7 + 4 is 11 and 11 + 4 is also 15.

In general terms, we can write the associative property of addition as

(a + b) + c = a + (b + c) where <em>a</em>, <em>b</em>, and <em>c</em> are variables that can represent any number.

Write an equation in slope-intercept form for the line that passes through the

Pavlova-9 [17]

Make slope intercept
3x - y = 5
3x = y + 5
y = 3x - 5
Parallel = same slope
Slope = 3
Y = 3x + b
Plug in the point
-2 = 3(-1) + b
-2 = -3 + b, b = 1

Solution: y = 3x + 1

If ABCD is a kite.<br> find m

Dvinal [7]

The answer would be 115°, the sum of interior angles in a kite is always 360° so if 41° and 89° equal 130° subtract 130° from 360° and that gives you 230° divide that by two for each side of the kite missing and you get 115°

<h3>Answer:</h3>

y = -(x -3)² +3 . . . . (agrees with your answer)
see the attachment for a graph

<h3>Step-by-step explanation:</h3>

Factoring the leading -1 from the first two terms, we have ...

... y = -(x² -6x) -6

Adding 9 inside parentheses to complete the square, then adding the opposite amount outside parentheses, we have ...

... y = -(x² -6x +9) -6 +9

... y = -(x -3)² +3
