Answer:</h3>
x² + y² = 50
<h3>
Step-by-step explanation:</h3>
The circle centered at (h, k) with radius r has equation ...
... (x -h)² + (y -k)² = r²
You have (h, k) = (0, 0), so all we need to do is find r². We can do that by choosing r² so that the equation is true at the given point.
... x² + y² = (5)² + (-5)² = 25 + 25 = 50
Your equation is x² + y² = 50.
you have to divide 5 divided by 3/10 to get your answer
Answer: Depends on the orders pairs
Step-by-step explanation: You didn’t include the ordered pairs so I’ll just do an example.
(1,5). (2,11). And(6,13) Theese orders pairs represent a function because, there are no repeating X values.
(2,5) (2,10) and (5,45)
Theese ordered pairs do NOT represent a function because, the X values repeat.
A function can be linear and nonlinear, they can have repeating Y values but NO repeating X values.
A trick for this is to put a piece of paper and cover sections and see if your line “turns back”.
