Step-by-step explanation:
The formula for a circle of radius r centered at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...
(x -2)^2 +(y -(-1))^2 = 4^2
(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A
Answer:

Option A is correct.
4) Midpoint is (2.5,0)
Option B is correct.
5) The factors are (x+4)(x-7)
Option C is correct.
6) The factors are (x+4)(x+2)
Option A is correct.
Step-by-step explanation:
Question 3
Find midpoint of the following:
(2,-7), (-10,8)
The formula used to find midpoint is:
We have
Putting values and finding midpoint
So, Midpoint is (-4,0.5)
Option A is correct.
Question 4
Find midpoint of the following:
(2,-10), (3,10)
The formula used to find midpoint is:
We have
Putting values and finding midpoint
So, Midpoint is (2.5,0)
Option B is correct.
Question 5
Factor each completely
We will break the middle term and find factors
So, the factors are (x+4)(x-7)
Option C is correct.
Question 6
Factor each completely
We will break the middle term and find factors
So, the factors are (x+4)(x+2)
Option A is correct.
Answer:
Just the second one is correct
