The running time for movie a is 39 minutes more than twice the running time for movie b. if the running time for movie a is subtracted from triple the running time for movie b, the result is 47 minutes. find the running times for each movie.

Let the running time for movie b = x minutes

Running time for movie a = (x + 39) minutes

3x - (39 + x ) = 47 minutes

3x - x = 47 + 39 minutes

2x = 86 minutes, x = 43 minutes

So movie b runs 43 minutes

Movie a runs 43 + 39 = 82 minutes

a) + x direction, b) .

Step-by-step explanation:

a) According to the Cartesian plane, an eastward translation implies a movement in the +x direction.

b)
