Hey there!
Here is your question -
In this equation, you're looking for n alone. To keep the variable alone, you have to do the opposite of what's happening to the variable.
In this equation, 12 is being added to n. The opposite of that is subtracting 12.
Subtract 12 from both sides -
Your answer is -8.
Hope this helps! :)
Answer:
<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the center (0, -1) and the radius r = 5 <em>(look at the picture)</em>.
Substitute:
<em>use (a + b)² = a² + 2ab + b²</em>
<em>subtract 25 from both sides</em>
