X^2+y^2-6x+16y-152=0

Mathematics
1 answer:
NikAS [45]3 years ago
3 0
X² + y² - 6x + 16y - 152 = 0
x² - 6x + y² + 16y - 152 = 0
x² - 6x + y² + 6y = 152
(x² - 6x + 9) + (y² + 6y + 9) = 152 + 9 + 9
<u>(x - 3)²</u> + <u>(y + 3)²</u> = <u>170</u>
  170         170       170
(x - 3)²/170 + (y + 3)²/170 = 1

Anyone pzzz answer this giving brainlist and 50 points for correct answer
Nuetrik [128]

Answer:

see below

Step-by-step explanation:

12x+24x+18 = 36x+24-6

Combine like terms

36x+18 = 36x+18

Subtract 36x from each side

36x+18-36x = 36x+18-36x

18 = 18

This is always true, so the equation is true for all values of x

Find the radius of a circle whose area is 576π m²
k0ka [10]

Answer:

r = 24 m

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here A = 576π , then

πr² = 576π ( divide both sides by π )

r² = 576 ( take the square root of both sides )

r = \sqrt{576} = 24
