Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
To find the constants (k)
divide y by x:
11/7 = 1.57
13/8 = 1.625
15/9 = 1.66
17/10 = 1.7
Each answer is different, therefore y does not vary directly with x.
