Step-by-step explanation:
Given:
Our initial temperature is 88.6
It lowers every minute 2 degree . We want it to stay greater 60.5.
So our inequality is
[tex]88.6 - 2m > 60.5[/tex]
Why?
The left side is in a linear equation form because we have a initial temperature and then it decreases constantly every period of time. Using that info, that is the same as a decreasing linear function.
We put greater than because it says stay above.
So know we solve for m.
[tex]88.6 - 2m > 60.5[/tex]
[tex] - 2m > - 28.1[/tex]
[tex]m <14.05[/tex]
Remeber when dividng by a negative the sign flips. So
m<14.05
