Item 4 Compounds A and B are used in an experiment. The equation y=500(0.5)x represents the remaining amount of compound A, in grams, after x hours. The table shows the remaining amount of compound B. Time (h) Grams of B 1 200 2 100 3 50 What is the positive difference in the initial amount of each compound? Enter your answer in the box. g

c

step-by-step explanation:

at least i think its

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
