**Damon**, Sunday, August 7, 2011 at 5:43pm2) 27 + 18 -3 = 42 agree

12) I would say positive, burning time = k * height

13)f(x) = 2 - (x-2) = 4-x

**Henry**, Sunday, August 7, 2011 at 5:55pm2. 42 is correct!

12. c is correct.

13. X = 2,3,4.

F(x) = Y = 2,1,0.

(x,y)

(2,2)

(3,1)

(4,0).

m = (2-1) / (2-3) = 1/-1 = -1.

m = (1-0) / (3-4) = 1/-1 = -1.

m is the same @ all given points. So

the function is a linear Eq.

(2,2).

Y = mx + b = 2,

-1*2 + b = 2,

-2 + b = 2,

b = 4.

F(x) = -x + 4.
