<h2>
Hello!</h2>
The answer is:
Center: (1,-2)
Radius: 4 units.
<h2>
Why?</h2>
To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:

Where,
"h" and "k"are the coordinates of the center of the circle and "r" is its radius.
So, we need to complete the square for both variable "x" and "y".
The given equation is:

So, solving we have:



Now, we have that:

So,
Center: (1,-2)
Radius: 4 units.
Have a nice day!
Note: I have attached a picture for better understanding.
Given:
Point Q is on line segment PR.
QR = 3x, PQ = x + 6, and PR = 5x – 4.
To find:
The numerical length of PQ.
Solution:
Since, point Q is on line segment PR, so by segment addition property, we get





The value of x is 10.
Now,

Putting x=10, we get


Therefore, the numerical length of PQ is 16 units.

Plug in and determine solution
Step-by-step explanation:#9-11 plug in the degrees C on the left side of the table into the equation and that should give you the degrees F, something like with #9; F = 9/5 (0) + 32.
#12-13, they have a relationship because Celsius can be converted to Farenheit and vise versa
Answer:
(x²+x+1) + 2/(x-1)
Step-by-step explanation:
(x³ - x² + x² - x + x - 1 + 1 + 1)/(x - 1)
[x²(x-1) + x(x-1) + 1(x-1) + 2]/(x-1)
(x²+x+1) + 2/(x-1)
