Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

Answer:
Infinite Amount of Solutions
Step-by-step explanation:
Step 1: Write equation
3(4x + 6) = 2(6x + 9)
Step 2: Solve for <em>x</em>
<u>Distribute:</u> 12x + 18 = 12x + 18
We see here that both sides of the equation are the same. Therefore, <em>x</em> is equal to infinite amount of solutions.
Another way to think about it is that the 2 lines are the same line. If both lines are the same, then they have infinite amount of solutions.
A: 6/18, or 1/3 (there are 18 marbles total, and 6 are red.)
b: 14/18, or 7/9 (There are 14 marbles that are not blue.)
Hope this helps!
