Given the equation of a circle below, find the diameter of the circle. Use only the digits 0-9 to enter the diameter.
kogti [31]

Answer:

10

Step-by-step explanation:

Standard form for a circle is

(x - h)² + (y - k)² = r²

where (h, k) is the center and r is the radius

--------------------------------

x² + y² - 18x + 24y = -200

Rearrange

(x² - 18x) + (y² + 24y) = -200

Complete the square for x

(x - 9)² + (y² + 24y) = -200 + (-9)²

Complete the sqaure for y

(x - 9)² + (y + 12)² = -200 + (-9)² + 12²

(x - 9)² + (y + 12)² =  25

Now the equation is in standard form

r² = 25

r = 5

Therefor Diameter = 10

2x-x+7 = x+3+4 is it no solution, one solution. or multiple solution if one of 2 please tell me what is x
ololo11 [35]

Answer:

x = x

Step-by-step explanation:

Basically, if you simplify the equation, you'll get x + 7 = x + 7 which means x = x which means you will have an infinite amount of solutions since x can be anything.
