Answer: B.
Step-by-step explanation:
1. By definition, the associative property of addition is:
2. Therefore, if you have the following expression:
You apply the Asociative property of addition by regrouping the numbers as following:
3. Then, you can conclude that the correct option is B.
Answer:
miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.
Step-by-step explanation:
As there is no graph mentioned here but the information are quite sufficient to answer the question.
We have points
From these points we can find the slope of the line .
From point slope formula
And assigning and
This slope is also the speed of the bird which is
As by plugging the values of any coordinate point we can confirm this.
Lets put , y-axis is the distance so in
minutes the the distance covered by the bird must be equal to to y-axis value which is
miles.
Now as in the bird has started from y-intercept value
so we can say that,the original distance of the bird from its nest is
.
So the correct choices are: and
The birds speed is per minute and is
away from its nest.
line N has slope m =
given a line with slope m then the slope of a line perpendicular to it is
= -
thus line N has slope - =
