So, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer
Well when x is -1, y = 0, then when x is 0, y = 3 so it is increasing there...then when x is 1, y = 6, so it is still increasing, but then it goes back down to 3 when x is 2
Therefore, the largest interval would be from -1 to positive 1 (-1,1)
Hope this helps

Answer:
Order from Least to Greatest
24/15 < 1 7/10 < 1 15/18
Step-by-step explanation:
Using the given inputs:
1 7/10 1 15/18 24/15
Rewriting all inputs as fractions:
1 7/10 1 15/18 24/15
17/10 33/18 24/15
The least common denominator (LCD) is: 90.
Rewriting as equivalent fractions with the LCD:
1 7/10 1 15/18 24/15
153/90 165/90 144/90
Sorting this table by the numerators of the equivalent fractions in order from least to greatest:
24/15 1 7/10 1 15/18
144/90 < 153/90 < 165/90
Therefore, the sorted inputs in order from least to greatest is:
24/15 < 1 7/10 < 1 15/18 Thank you :)
