Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
shut up and do your hw
No, that's associative.
i think its pretty much the same thing because matrix X1 X2 IS ACTUALLY X1 X2

it equals x1 it equals x1

Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
use the formula y-y1=m(x-x1)

No, that's associative.
f(x1) = (-5)2 + 3*(-5) + 5.1 = 25 - 15 + 5.1 = 15.1 f(x2) = (6)2 + 3*(6) + 5.1 = 36 + 18 + 5.1 = 59.1 f(x2)-f(x1) = 59.1 - 15.1 = 44 x2 - x1 = 6 - (-5) = 11 So average rate of change = 44/11 = 4
x2 - 4x + 1 = 0p=4q=1x = -p/2 +- sqrt((p/2)2 - q)x = -4/2 +- sqrt((4/2)2 - 1)x = -2 +- sqrt(4-1)x1= -2 + sqrt(3)x2= -2 - sqrt(3)
x²+6x+9=49 x²+6x-40=0 x1=-6/2 - Square root of ((6/2)²+40) x1=-3 - 7 x1= -10 x2=-6/2 + Square root of ((6/2)²+40) x2=-3 + 7 x2= 4

It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.
