Answer:

x^2 + (y-8)^2= 81

Step-by-step explanation:

the equation of a circle with a center at (0, 8) and a radius of 9.

To frame the equation of the circle we use center radius form of equation

(x-h)^2 + (y-k)^2= r^2

Where (h,k) is the center and 'r' is the radius

Given center is (0,8) and radius = 9

h = 0 , k= 8 and r= 9

Plug in all the values

(x-h)^2 + (y-k)^2= r^2

(x-0)^2 + (y-8)^2= 9^2

x^2 + (y-8)^2= 81

Which of the following is a solution to the equation x - 5/7 = -3/7
podryga [215]

Solve the equation:

          5              3
x  –  ——  =  –  ——
          7              7


           5
Add  ——  to both sides, so you get  x  isolated at the left-hand side:
           7

          5          5               3          5
x  –  ——  +  ——  =  –  ——  +  ——
          7           7              7           7

              3          5
x  =  –  ——  +  ——
              7           7


Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x  =  —————
               7

          2
x  =  ——     <———    this is the answer (first option:  2/7).
          7


I hope this helps. =)

What is the slope- intercept equation of the line that passes through(0,2) and (6,6)?
Vsevolod [243]

Answer:

y = 2/3x +2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

    = (6-2)/(6-0)

    =4/6

   =2/3

The slope intercept form of the equation for a line is

y= mx+b

y =2/3 x +b

We know the y intercept is 2  (the y intercept is when x=0)

y = 2/3x +2
