we are given in the problem the number of hours Peter has played for video games. In this case, f(x) is the number of hours of playing with x as the number of weeks of playing. In this case, the equation f(x) = 5x.
Answer:
y=-1/3x-3
Step-by-step explanation:
Minus 9 from both sides
7x = 49
X = 7
(400-300)/300 x 100 = 100/300 x 100 = 33.33% increase
<span>x + 3y = 9
-x + y = -1
X = 3
Y = 2
