Rachel drives at a constant speed of 70 miles per hour.
marishachu [46]

The linear function that models Rachel's distance as a function of time is:

D(x) = (70 mi/h)*x

<h3>How to find a function that models Rachel's distance as a function of time?</h3>

Remember the relation between speed and distance:

Distance = Speed*Time.

Here we know that the speed of Rachel is 70 miles per hour, then if she drives for x hours, the distance traveled will be:

D(x) = (70 mi/h)*x

So we found a linear function that models Rachel's distance as a function of time.

The average of three numbers is 25. The average of two of those numbers is 21. What is the value of the third number of the orig
Elza [17]

Answer:

b) 33

Step-by-step explanation:

You reverse the process of finding the second average, 21, which will help you find the original average, 25. First you multiply the second average, 21, to retrace your steps. We do this because the last thing we do when we find the average is divide. when you multiply 21 you get 42. Now you have the value of the first two numbers. Then you experiment with the numbers. To save time I'll get to the point. When you add 33 + 42 you get 75. Then you divide by 3 to get 25. You divide by three because the instructions say there was 3 numbers to start with. Hope this helps.
