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:

C
explanation : the equation is division and since you don’t know what the variable x is, you multiply 3 and 12 to find x

all answer wrong with you
Step-by-step explanation:
f(x)=3x-1
f(8)=3.8-1
=24-1
=23
f(g)=x2-x
f(8)=8.2-2
=16-2
=14
