Answer:
1 7/10 miles
Step-by-step explanation:
Sounds as tho' we want to calculate the total distance Ron walked. This would be:
8/10 mile + 9/10 mile = 17/10 miles, or 1 7/10 miles.
The range of function is { 0, -6, -9}
<h3><u>Solution:</u></h3>
Given that the function is:

Also given its domain is (-8, 0, 4)
<em><u>To find: Range of the function</u></em>
Domain of the function is possible input of the function that is "x" and range of the function is possible output of the function that is f(x)
As there are only three input values for "x" that are (-8, 0, 4) we can determine the range by calculating value of f(x) for each of the x
<em><u>For x = 8:</u></em>


<em><u>For x = 0:</u></em>

<em><u>For x = 4:</u></em>

Thus the range of function is { 0, -6, -9}
<span>2 x - 6 = 20, where x is the temperature in degrees Farhenheit 6 hours ago. 2 x = 20 + 6, 2 x = 26, x = 26 : 2, x = 13 degrees F. We can prove it: 13 * 2 - 6 = 26 - 6 = 20 degrees F ( the current temperature ) Answer: The temperature 6 hours ago was 13 degrees F.Hope this helps.
