THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(
harkovskaia [24]

Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2  miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs  12/ 2 = 6 laps.

If f and g are functions, then (fog)(x) is always equal to (gof)(x)<br><br> true or false
valentina_108 [34]

Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.
