Question 186590: I do not understand how to do this problem could someone please help me?
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=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?
-Predicted gun deaths in 2005 will be?
-Predicted gun deaths in 2008?
-Predicted gun deaths will be 11,160 in the year?

You can put this solution on YOUR website! You are given:
y= -1777x+27153
.
-Predicted gun deaths in 2005 will be?
x = 20005 - 2000
x = 5
Plugging it in:
y= -1777x+27153
y= -1777(5)+27153
y = 18268
.
-Predicted gun deaths in 2008?
x = 20008 - 2000
x = 8
Plugging it in:
y= -1777x+27153
y= -1777(8)+27153
y = 12937
.
-Predicted gun deaths will be 11,160 in the year?
11,160 is 'y' -- now, we solve for x:
y= -1777x+27153
11160 = -1777x+27153
11160 - 27153 = -1777x
-15993 = -1777x
-15993/-1777 = x
9 = x
or
2009
