Emily is making a punch that contains 75% apple juice and the rest ginger ale. The punch has 2 liters of ginger ale.
Flura [38]
For this item, we may let x be the number or liters of apple juice present in the ginger ale. The total volume of the punch then becomes
                                 total volume = 2 + x 
Then, considering that 75% of this is apple juice,
                                  x/(2 + x) = 0.75
                                   x = 0.75(2 + x) = 1.5 + 0.75x
                                          x = 1.5 + 0.75x
Also, for this item, the vaue of x is equal to 6 liters.

Find the equation of the line that passes through the points : (4 , -1 ) and (0 , -3)
Sergio [31]

Answer:

B. y= 1/2 x - 3

Step-by-step explanation:

base equation: y= mx+ b

slope(m) equation: \frac{y_{2}-y_{2}  }{x_{2} -x_{1} }

y2= -1    y1= -3

x2= 4     x1= 0

\frac{-1 - (-3)}{4-0} =\frac{2}{4} = \frac{1}{2}

y- intercept: -3

found by taking the y from (0,-3)
