Answer:
7.
Step-by-step explanation:
The equation of a circle is
(x - h)² + (y - k)² = r²
Where
(h, k) is the center and r is the radius, so we only need to work with r.
The expression states that
r² = 49 or the radius squared is equal to 49. So solve for r to find the radius.
r² = 49
Take the square root.
r = 7
The radius of the equation is 7.
The aim here is to get all of the x's onto one side and the numbers onto the other side:
We can start by subtracting x from each side
2x+11=1
We can then subtract 11 from both sides
2x=-10
Finally, we can divide both sides by 2 leaving us with:
x = -5
