The measurement of ∠KNL is 102°
First, you must set up an equation to find x.
Then, you must simplify both sides of the equation.
Next, subtract 3x on both sides.
Then, subtract 2 on each side.
Next, divide 2 on each side.
Now that we have the value of x, we can substitute it in for angle KNL.
°
Answer:
Part a. The graph does not model a proportional relationship.
Part b. The values in table model a proportional relation.
3.5 minutes per mile.
Step-by-step explanation:
Part a.
The graph shown in the question representing Janet's data is not a straight line although it passes through the origin.
That is why the rate of change of distance with time is not constant.
Therefore, the graph does not model a proportional relationship.
Part b.
If we plot the data in the table using distance in miles along the y-axis and time in minutes along the x-axis, then we will get a straight line passing through the origin.
So, the values in the table model a proportional relation.
Now, Tarik's unit rate in minutes per miles will be minutes per mile. (Answer)
