-3 + 4.5 + 8 + 6 = -x-1
15.5 = -x-1
x-1 = -15.5
x = -1/15.5
x = -2/31
shut up and do your hw
i think its pretty much the same thing because matrix X1 X2 IS ACTUALLY X1 X2
It is linear. The highest power is 1 (x = x1, y = y1) so it is linear.

This question can only be answered if the probability distribution functions of X1, X2 and X3 are known. They are not and so the question cannot be answered.
it equals x1 it equals x1

shut up and do your hw
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
find number of integer solution of X1+x2+x3=24
use the formula y-y1=m(x-x1)
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.

By factoring: x(1-x) = 0 Therefore: x = 0 or x = 1
