Answer: 15.7 minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes.
Then they are able to reduce that time by 10
If their final time is 3.96 minutes, then
x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7
Hence, their beginning time was 15.7 minutes.
Answer: The inverse is f^-1 (x) = x - 11
There’s so diagram if you can provide a picture
<span>The graph of temperature versus pressure is a straigh line rising to the right. It Using the value above, the equation is P = 2.5522T + 699. The temperature is directly proportional to pressure. The pressure of the gas 0C using the equation,
</span>P = 2.5522T + 699
P = 2.5522(0) + 699
P = 699
As x goed up one y goes down one so rate of change is -1
