Homer wants to identify the center and radius of the circle defined by the equation x² + y² - 14x + 2y - 25 = 0. He follows these steps:
Step 1: (x² – 14x) + (y2 + 2y) = 25
Step 2: (x2 – 14x + 49) + (y2 + 2y + 1) = 25
Step 3: (x - 2)2 + (y + 1)2 = 25
Step 4: The center is (7.-1), and the radius is 5.
At which step did Homer make a mistake, and what was it?

How can you find the conditional probability of a given b as the fraction of b’s outcomes that also belong to a, and interpret the answer in terms of the model? i just need a good explanation

If you could answer these your a life saver

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
