Question 144461: Could someone please help me with this one?
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 2002, x = 5 corresponds to 2005 and so on. Predict the number of gun deaths in 2005 & 2008. In what year will the number of gun deaths be 11, 160?
Thank you!

:
y = 1777x + 27153
:
In 2005, x = 5, substitute 5 for x in the above equation
y = 1777(5) + 27153
:
y = 8885 + 27153
:
y = 36,038 in 2005
;
Likewise for 2008, substitute 8 for x in the same equation and find y

:
Write the same equation, substituting 11160 for y like this, and find x:
1777x + 27153 = 11160
:
1777x = 11160 - 27153, subtract 27153 from both sides
:
1777x = -15993
x =
x = -9
:
Subtract 9 from 2000 and you have 1991, they had 11,160 deaths (according to this)
