You can create a right angled triangle.
Find the hypotenuse.
The third point of the triangle is (1,0)
using pythagoras, the value of a is 2, b is 3. 2^2 +3^2 = 13.
Therefore the distance between the two points is

Step-by-step explanation:
-32x+45-7(2x-9)=101
parenthesis first
-32x+45-14x+63=101
just combine like terms
-46x+108=101
minus 108 both sides
-46x= -7
answer is x 7 over 46
Answer:
The number of supervisor in the factory is 9 .
Step-by-step explanation:
Given as :
The ratio of workers to supervisors and factories 32 : 2
let the number of workers = 32 x
And The number of supervisors = 2 x
The ratio of male workers to female workers is 6:5
Let The number of male workers = 6 y
And The number of female worker = 5 y
The number of female workers at the plant = 80
So, 5 y = 80
∴ y =
I.e y = 16
So, The number of male workers = 6 y = 6 × 16 = 96
Thus The Total number of worker in the factory = The number of male workers + The number of female workers at the plant
Or, The Total number of worker in the factory = 96 + 80 = 146
Now , Again
∵ The ratio of workers to supervisors in factories 32 : 2
So, The number of workers = 32 x
I.e 146 = 32 x
∴ x = = 4.5
So, The number of supervisors = 2 x = 2 × 4.5 = 9
Hence The number of supervisor in the factory is 9 . Answer
