Question 309923: The equation y=-1777x+27153 can be used to predict the number y of gun deaths in the united states x years after 2000, that is, x=0 corresponds to 2000, x=2 corresponds to 2002, x=5 corresponds to 2005, and so on. Predict the number of gun deaths in 2005 and 2008. In what year will the number of gun deaths be 11,160?

The equation y=-1777x+27153 can be used to predict the number y of gun deaths in the united states x years after 2000, that is, x=0 corresponds to 2000, x=2 corresponds to 2002, x=5 corresponds to 2005, and so on. Predict the number of gun deaths in 2005 and 2008. In what year will the number of gun deaths be 11,160?
----------------------
d(x)=-1777x+27153
d(5) = -1777*5 + 27153 = 18268
---
d(8) = -1777*8 + 27153 = 12937
--------
Solve 11,160 = -1777x + 27153
-1777x = -15993
x = 9
--
Year = 2009
