1 3/5
or exact form is 8/5
Answer:
0.03
Step-by-step explanation:
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
The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
3x-4y = 9
(-1.3)
3 (-1) -4 (3) = 9
-3-12 = 9
-15 = 9 (Does not belong)
(2/3, -7 / 4)
3 (2/3) -4 (-7/4) = 9
6 + 28 = 9
34 = 9 (Does not belong)
(-5, -6)
3 (-5) -4 (-6) = 9
-15 + 24 = 9
9 = 9 (Yes, it belongs)
(1, -3 / 2)
3 (1) -4 (-3/2) = 9
3 + 6 = 9
9 = 9 (Yes, it belongs)
answer
ordered pairs are
(-5, -6)
(1, -3 / 2)
