Hey there!
Let's write an equation given this information. We will use x to represent the number.
2(x-7)=5
Now, we use the distributive property to remove the parentheses.
2x-14=5
Now, we add 14 to both sides.
2x=19
We divide both sides by 2.
x=9.5
Therefore, our number is 9.5
I hope this helps!
Answer:
Center: (-1,8)
Radius: 1
The graph is attached.
Step-by-step explanation:
The equation of the circle has the form:

Where (h,k) is the point of the center of the circle and r is the radius of the circle.
The equation given in the problem is

Therefore:
h=-1
k=8
Then, the center is (-1,8) and radius is 1.
You can graph the circle with its center at the (-1,8) and a radius of 1 as you can see in the figure attached.
