Answer:

Step-by-step explanation:
The equation for a circle is given by:

Where (h,k) is the center and r is the radius.
The center is the red dot, which is (1,2). Thus, h=1 and k=2.
To find the radius, you need to use the distance formula. We are given two coordinates: the center (red dot) at (1,2) and a blue dot on the circle at (2.5,4). Find the radius by using the distance formula:

Let (1,2) be <em>x₁ </em>and <em>y₁ </em>and let (2.5,4) be <em>x₂ </em>and <em>y₂. </em>Therefore:

Thus, r is 2.5.
Plugging these numbers into the equation, we have:

-3x + 4 > 5
-3x > 5 - 4
-3x > 1
x < 1/-3
x < -1/3
Answer:
The first answer is correct.
Step-by-step explanation:
Where R represents the amount of rent Vanessa pays, 2r is double that amount, and 2r - 12 would be twelve dollars less than double.
It depends on how much the invitations cost at each shop.
