Track A takes 20 minutes
Track B takes 15 minutes
In 1 minute track be will do a fraction of 1/20, while track B will do 1/15
Both tracks in a minute = 1/20+1/15
= 35/300
Therefore the two tracks will take 300/35 minutes to fill the 200 cubic feet
That is 300/35
= 8.57 minutes
≈ 9 minutes
The common difference is 5 each time. Take for example -9 and -4 it’s goes up 5, and then 1 and 6 it goes up five and so on,hope this helped!
I think it is { y:y less than or equal to-3} because -3 is the y-Intercept and the slop is going down cuz it’s an negative
The sequence in the story:
13, 13, 13, 13
<h2>This can be <u><em>
BOTH</em></u> because 13*1=13, and 13+0=13.</h2>
