<PRE><B>Question 148479</B>
The equation f(x)= -1777x + 27,153 can be used to predict the number y of gun deaths, in the U.S. x years after 2000, that is, x=3 corresponds to 2003, x=4 corresponds to 2004, and so on...
------------------------------------- 
Predict the number of gun deaths in 2004 and 2007.
f(4) = -1777*4 + 27153 = 20045
f(7) = -1777*7 + 27153 = 14714
----------------------
In what year will the number of gun deaths be 11,160?
11,160 = -1777x + 27153 ; x=9
Year = 2009
