Answer: OPTION B.
Step-by-step explanation:
Given the endpoints of the diameter of the circle, we need to find the midpoint, which is the center of the circle.
The following formula is used to calculate the Midpoint:

Given the endpoints of the diameter of the circle:

We can identify that:

Then, we can substitute these values into the formula:

Therefore, the center of the circle is: 
1 1/2 cause your getting half not just sum
A is (2, -1)
The X axis will not change since A is not going left or right of (2,2). You would count down 3 spaces for the y-axis and that would land you at -1 or you could solve by subtraction.
2-3= -1
Answer:
y = 4/5

<em>Identify</em>
7/8y + 1/2 = 1 1/5
<u>Step 2: Solve for </u><em><u>y</u></em>
- Convert to improper fraction: 7/8y + 1/2 = 6/5
- [Subtraction Property of Equality] Subtract 1/2 on both sides: 7/8y = 7/10
- [Division Property of Equality] Divide 7/8 on both sides: y = 4/5
Answer:


Step-by-step explanation:
Given

Solving (a): 
We have:

Express f(x) as y

Swap x and y

Add 8 to 


Square both sides

Rewrite as:

Express y as: 

To determine the domain, we have:
The original function is 
The range of this is: 
The
of the
function is the
