You can group first two conjunctions and second two:

.
In first brackets you have common

and in second brackets common is 5:

.
Well you'd see if it's closer to 10000 or 20000.
In this case it would round to 20000.
Answer:
you will only move 15 units up
Step-by-step explanation:
since the y is the only one that has a value, then you will have to focus more on the direction where the y will go. and since the y's value is positive then you will have to go upwards.
Answer: y2-y1/x2-x1=-1-3/3-3=-4/0=undefined.
Step-by-step explanation:
Answer:
The circle's centre is at the position (3, 5), and it has a radius of 2
Step-by-step explanation:
First let's put it in a useful format by completing the squares:
x² + y² - 6x - 10y + 30 = 0
x² - 6x + y² - 10y = -30
x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25
(x - 3)² + (y - 5)² = 4
This tells us that the centre position is (3, 5) and the radius is √4, or 2
