OpenStudy (anonymous):
Ok
OpenStudy (anonymous):

OpenStudy (anonymous):
so if x = 1... you do the math and that will be the number of gun deaths during 2001
OpenStudy (anonymous):
if x = 2 thats the # of deaths by projectile in 2002
OpenStudy (anonymous):
they want to know what year 12,937 deaths occur
OpenStudy (anonymous):
So being that y is always the number of deaths... you can put it in and see what x is equal to...
OpenStudy (anonymous):
this problem crazy.

if you solve: 12,937 = -1777x +27,153 you should get x = 8
OpenStudy (anonymous):
so for the first one, put in x = 5 (I hope you have a calc.)
OpenStudy (anonymous):
that's the number of deaths in 2005
OpenStudy (anonymous):
-1777(5) + 27,153 = number of deaths in 2005
OpenStudy (anonymous):
-1777(7) + 27,153 = the number of deaths in 2007

soo there were 18268 in 2005? and 14714 in 2007?
OpenStudy (anonymous):
12,937= 1777(x) + 27,153
solve for x and you have the number of years after 2000 (or before if neg) that 12,937 deaths wend down.
OpenStudy (anonymous):
leme chk your ans.
OpenStudy (anonymous):
yea and...yea, those are right.
OpenStudy (anonymous):

I forgot to put the neg in front of the 1777 up there in the x equation... my bad
OpenStudy (anonymous):
thats good , im trying to figure it out.
OpenStudy (anonymous):
(12,937 - 27,153)/-1777 = 8
OpenStudy (anonymous):
so it would be 2008?
OpenStudy (anonymous):
nice... yep
