30 points if correct. susan recorded the cumulative number of miles she ran over several days on the following graph. which of the following would be the best prediction for the value of the independent variable for when susan has run a total of 64 miles. a. 42 days b. 64 days c. 128 days d. 32 days.

Hey there,

I believe your answer is C) 128 days.

Step-by-step explanation:

Reason-

As you can see on the graph the number of days running is exactly doubled on the graph.

So because she ran 64 days you would just double that number: 64*2=126

Thus you end up with 128 days or letter C.

Hope this helps!

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
