Answer:
steps below
Step-by-step explanation:
y = (x-3) / x
replace x and y:    x = (y-3) / y
y - 3 = xy
y - xy = 3
y(1 - x) = 3
y (f'(x)) = 3 / (1-x)

2. is 29
3. is A
4. is A
        
             
        
        
        
12 bottles = 6 liters
--------------------------------------------------------
Find 1 bottle
--------------------------------------------------------
12 bottles = 6 liters
1 bottle = 6 ÷ 12
1 bottle = 0.5 liters
1 bottle = 500 ml

Answer:
(x + 1)(3x - 10)
Step-by-step explanation:
Given
3x² - 7x - 10 
Consider the factors of the product of the x² term and the constant which sum to give the coefficient of the x- term.
product = 3 × - 10 = - 30 and sum = - 7
The factors are + 3 and - 10
Use these factors to split the x- term
3x² + 3x - 10x - 10 ( factor the first/second and third/fourth terms )
3x(x + 1) - 10(x + 1) ← factor out (x + 1) from each term
(x + 1)(3x - 10), thus
y = (x + 1)(3x - 10) ← in factored form
