X^2-6x+9
x^2-3x-3x+9
x(x-3)-3(x-3)
(x-3)(x-3)
(x-3)^2
Step-by-step explanation:
the average change rate of a function f(x) in an interval [x1 .. x2] is
(f(x2) - f(x1)) / (x2 - x1)
in our case that is
(7000 - 2500) / (20 - 0) = 4500 / 20 = 225
the population changed in average by 225 people per year from 1900 to 1920.

2_____0011234445667889
3_____00011227
The stem is represented in units of hundred thousand and the leaf in ten thousand. Therefore from the plot above, the most expensive house will be the one with both the highest hundred thousand and ten thousand placed value.
300,000(stem) + 70,000(leaf) = 370,000
