Get it now. When you subtract you reverse the sign of the bottom one and add.

Math
y=-x+4 y=-2x-4 ------------- SUBTRACT these two equations 0 = -x -(-2x) + 4 - (-4) 0 = -x + 2x + 4 + 4 0 = x + 8 x = -8
January 14, 2015

Math
y = -x + 4 y = -(-8) + 4
January 14, 2015

Math
for elimination subtract as is y=-x+4 y=-2x-4 ------------- 0 = 1 x + 8 so x = -8 then get y = 8+4 = 12
January 14, 2015

Math
I did the earlier ones with elimination here is substitution y = (-x+4) so (-x+4) = -2x - 4 x = -8 then go back and get y y = -x + 4 = 8+4 = 12

10 x - 8 y = 20 -10 x + 2 y = -20 ----------------- add 6 y = 0 y = 0 if y = 0 5 x = 10 x = 2 so the two lines intersect at (2 , 0)

1. If f(x) = ln(1 - 2x), then find f '(x) f' = [ 1/(1-2x) ]( -2) = -2/(1-2x) = 2/(2x-1) I do not understand your second function

x = 15 t h = 5 t + 5 = 5(t+1) y^2=x^2+h^2 = 225t^2 + 25t^2 + 50 t + 25 y^2 = 250 t^2 + 50 t + 25 2 y dy/dt = 500 t + 50 now at t = 3 y^2 = 250(9)+150 +25 = 2425 y = 49.2 so 2(49.2) dy/dt = 1500 + 50 = 1550 dy/dt = 15.8 m/s

physics
change of momentum = 2520 v average force = change of momentum/time F = 2520 v/t work = force * distance 4310 = 2520 v/t * 22.4 or v/t = .0764 or t = v/.0764 now if force were constant d = (1/2) a t^2 44.8 = a t^2 v = a t so a = v/t so 44.8 = v t = v^2/.0764 v^2 = 3.42 v = 1....
