1/5*x-13=58
1/5x=58+13
1/5x=71
X=71*5
x=355
Answer:
(x - 2)² + (y - 9)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (2, 9) and (x₂, y₂ ) = (2, 6)
r =
=
= = = 3
Centre = (h, k) = (2, 9) and r = 3, thus equation of circle is
(x - 2)² + (y - 9)² = 9
Use the distributive property.
This states that: a(b+c)= ab+ac
So,
-6*a= -6a and -6*8= -48
-6a+-48
This is the most you can simplify this problem.
I hope this helps!
