Answer:
Option C is correct.
The answer for the given expression is 0.
Step-by-step explanation:
Given the statement: Two times the difference of one-third of a number and three. and also variable given is 9.
Let x be the variable or number.
"One-third of a number" means 
Also, "difference of one third of a number and three " means 
Now, "Two times the difference of one-third of a number and three" means 
Then, the expression for the given statement : 
Substitute the value of x =9 in above expression we have;
=
=
= 0
therefore, the answer for the given expression is, 0

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>
