Answer:
<h2>
B. (x-4)(x+i)(x-i) </h2>
Step-by-step explanation:
x³-4x²+x-4=
=x²(x-4)+(x-4)
=(x-4)(x²+1)
=(x+4)(x-i²)
<h3>=
(x-4)(x+i)(x-i) </h3>
Answer:
y = x - 1
Step-by-step explanation:
if it goes up to the right its positive x and just take away 1 because on the Y-axis it goes down 1
Answer:
sample variances
Step-by-step explanation:
The pooled variance method is used to estimate the variance of several different population with different means, but are assume to have the same variance.
The weights represent the sample variances.
So the correct answer is
sample variances
