Given:
The equation of a circle is:
To find:
The center of the circle and its radius.
Solution:
The standard form of a circle is:
...(i)
Where, (h,k) is center and r is the radius of the circle.
The given equation of the circle is:
Write the given equation in standard form of a circle.
On further simplification, we get
...(ii)
On comparing (i) and (ii), we get
Therefore, the center of the circle is (0.5,1) and radius is 2 units.
I disagree, the equation is in y=mx+b form. The slope, or m, is 0, so the equation is y=0x+7. That simplifies to y=7.
Plz mark me brainliest!
Hope this helps!

have a nice day!! :)
Answer:
x=-3.5
Step-by-step explanation:
-3x=10.5 divide both sides by -3
Its 43, or H. Why? Well its quite simple. Take the amount he was fined, divide that by 17. If you do that you get 13. Take 13 and add it to the speed limit of 30. You get 43.
