Step-by-step explanation:
![\displaystyle [x - h]^2 - [y - k]^2 = r^2 → Hyperbola\:Equation \\ [x - h]^2 + [y - k]^2 = r^2 → Circle\:Equation \\ [h, k] → Centre](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Bx%20-%20h%5D%5E2%20-%20%5By%20-%20k%5D%5E2%20%3D%20r%5E2%20%E2%86%92%20Hyperbola%5C%3AEquation%20%5C%5C%20%5Bx%20-%20h%5D%5E2%20%2B%20%5By%20-%20k%5D%5E2%20%3D%20r%5E2%20%E2%86%92%20Circle%5C%3AEquation%20%5C%5C%20%5Bh%2C%20k%5D%20%E2%86%92%20Centre)
According to the equations in the exercises, in the parentheses, ALL NEGATIVE SIGNS give the OPPOSITE terms of what they REALLY are, so be EXTREMELY CAREFUL with your translations:
9. [4, 11]
+ 3 + 4
_____
[7, 15] → (x - 7)² and (y - 15)²
8. [−2, 8]
+ 3 + 2
_____
[1, 10] → (x - 1)² and (y - 10)²
7. [−8, −14]
+ 3 - 5
______
[−5, −19] → (x + 5)² and (y + 19)²

So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*

(x is the number of years passed)
Answer:

Step-by-step explanation:
Given parameters:
Points = (1,1) and (5,-5)
Unknown:
Slope = ?
Solution:
The slope of the a line is the ratio of the rise of a line to its run.
Slope =
x1 = 1
y1 = 1
x2 = 5
y2 = -5
Insert the parameters and solve;
Slope =
=
=
