x-1+5=2x-1
becomes
-x = -5
so x=5
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)
i think its pretty much the same thing because matrix X1 X2 IS ACTUALLY X1 X2
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
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.
