\[y=\frac{ 3 }{ 2 }t-\frac{ 5 }{ 2 }\]
OpenStudy (ibbutibbu.):
Is this correct?
OpenStudy (ibbutibbu.):
If so, then just substitute the value 3 where there is a t
OpenStudy (ibbutibbu.):
\[y=\frac{ 3 }{ 2 }(3)-\frac{ 5 }{ 2 }\]
OpenStudy (ibbutibbu.):
What is \[\frac{ 3 }{ 2 }\] times 3?

So its like \[\frac{ 3 }{ 2 }\left( 3 \right)-\frac{ 5 }{ 2 }\]
OpenStudy (ibbutibbu.):
Precisely.
OpenStudy (anonymous):
wait.. \[\left[\begin{matrix}3 & 3 \\ 2 & 0\end{matrix}\right]\]

No, you cant divide anything by Zero
OpenStudy (anonymous):
... so its 9 over 2?
OpenStudy (ibbutibbu.):
Yes, I think so...
OpenStudy (ibbutibbu.):
then, you add 9/2 and 5/2 to get...?
OpenStudy (anonymous):
So that means \[\frac{ 9 }{ 2 }-\frac{ 5 }{ 2 }=\frac{ 4 }{ 2 }\ 4\div2=2?\]
