Answer:
The x-coordinate of the solution to this system of equations is <u>1</u>.
Step-by-step explanation:
Given,

We have to find out the x-coordinate of the equation.
Solution,
Let 
Again let 
Now using elimination method we will solve the equations.
For this we will add equation 1 and equation 2 and get;

Now on dividing both side by '9' we get;

Hence The x-coordinate of the solution to this system of equations is <u>1</u>.
g(f(x)) = 2
_____
The value of the argument to function g is immaterial to its result. g(x) is 2 for any value of x.
Answer:
x^2-18x+y^2+18y+137=0
express both x and y term in completed square form
(x-9)^2 -81+(y+9)^2-81+137=0
(x-9)^2+(y+9)^2-25=0
(x-9)^2+(y+9)^2=5^2
here the x coordinate of the centre is +9
y coordinate is -9(the negative value of the value associated with the x and y square brackets)
radius=5
