<PRE><B>Question 250091</B>
equation is:


y = -1777*x + 27153


x = 0 corresponds to the year 2000.


you want to predict the number of gun deaths in 2004 and 2007.


2004 corresponds to x = 4
2007 corresponds to x = 7


in 2004, the equation becomes y = -1777*4 + 27153 = 20045
in 2007, the equation becomes y = -1777*7 + 27153 = 14714


to solve for what year the total number of gun deaths will be 11160, you need to substitute for y in the equation to get:


11160 = -1777*x + 27153
subtract 27153 from both sides of this equation to get:
11160 - 27153 = -1777*x
combine like terms to get:
-15993 = -1777*x
divide both sides by -1777 to get:
-15993/-1777 = x
solve for x to get:
x = 9


the year 2000 + 9 = the year 2009


your answers are:


number of gun deaths in 2004 = 20045
number of gun deaths in 2007 = 14714
gun deaths will be 11160 in 2009
