totally answer.
Strong, they are all close together and close to the line.
The answer is y = +8
Explanation:
Since they tell us what x equals (3), let's plug that into the equation
y = (3) + 5
Now, we can just add 3 and 5 together, which we get 8
y = +8
<u>Given</u>:
The distance (in kilometers) Dora hiked is modeled as a function of time.
We need to determine the average rate of change in distance hiked, measured in kilometers per hour, between 8:30 am to 1:30 pm.
<u>Average rate of change:</u>
Let us write the time and the distance hiked in coordinates for the time 8:30 am and 1:30 pm.
Thus, the coordinates are (8.30, 4) and (1,12)
The average rate of change can be determined using the formula,
Substituting the points (8.30, 4) and (1.30,12), we get;
Rounding off to the nearest whole number, we get;
Therefore, the average rate of change is -1.
The nearest whole number is... 12560. It is already a whole number!
