Answer: (x + 1)² + (y - 6)² = 9
<u>Step-by-step explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r²
Given: (h, k) = (-1, 6), r = 3
Input the given values into the equation:
(x - (-1))² + (y - 6)² = 3²
(x + 1)² + (y - 6)² = 9
(x+2)(x-8) you got to find the factors of 16 and they have to add up to -8
The ratio is 2 : 9
Step-by-step explanation:
Given:
The number of sports store = 4
The number of clothing store = 9
The number of jewellery stores = 5
To Find :
The ratio of number of sports stores to the total number of stores
Solution:
The ratio of number of sports stores to the total number of stores
=
The total number of stores = number of sports store + number of clothing store + number of jewellery store
The total number of stores = 4 + 9 + 5
The total number of stores = 18
Now the ratio is
= or 4 : 8
The ratio after reduction is
= or 2 : 9 or 2 to 9
You need the following equation
