Question 147900: the equation y=-1777x+27,153 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=3 corresponds to 2003,x=6 corresponds to 2006 and so on.predict the number of gun deaths in 2006 and 2007. in what year will the number of gun deaths be 11,160?

You can put this solution on YOUR website! SOLUTION:
The number of gun deaths y in 2006 can be found by substituting x = 6 into the formula y=-1,777x+27,153.
y = -1,777*6 + 27,153 = 16,491
The number of gun deaths y in 2006 can be found by substituting x = 7 into the formula y=-1,777x+27,153.
y = -1,777*7 + 27,153 = 14,714
To find in what year the number of gun deaths will be 11,160, solve the following equation for x:
-1,777x+27,153 = 11,160
1777x = 15993
x = 9
So in 2009 the number of gun deaths will be 11,160.
