Answer: Associative property of addition
Step-by-step explanation: The statement (6 + 2) + 1 = 6 + (2 + 1) represents the associative property of addition. Notice that the addends or the numbers were adding are the same on both sides of the equals sign 6 + 2 + 1 but on the left side, 6 and 2 are grouped together and on the right side, 2 and 1 are grouped together.
The associative property of addition says that when we are adding more than two numbers, the grouping of the addends does not affect the sum.
Here, notice that 6 + 2 is 8 and 8 + 1 is 9. On the right side, the order of operations tells us to begin inside the parentheses so we have 2 + 1 which is 3 and 6 + 3 is also 9.
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.
Answer:
The answer is option 2.
Step-by-step explanation:
In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.
For example,
Let t = 1,
Let t = 5,
Therfore, as time increases, distance will also increase.
Answer:
a. t
b. a (or x = a)
c. r
d.
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so
b. If 
draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so 
c. Note that 
then
d. Coordinates of point L are (c,t), coordinates of point K are (a,p)
