Answer:
Step-by-step explanation:
Let the amount of flour left be .
Initial amount of flour = 18 cups
Cups used for 1 batch of muffins = 3
∴ Cups used for batches =
Amount left in the container is given as:
Therefore, the equation to show how much flour is left in the container after x batches of muffins is .
The graph of it is shown below.
Find the x and y intercepts and then join the line.
At x intercept,
So, x intercept is
At y intercept, ,
So, y intercept is
Join these two points to plot the graph.
Answer:
x=4 x=-2
Step-by-step explanation:
x+4 x
----------- = ------------
4 x-2
Using cross products
(x+4)(x-2) = 4x
FOIL
x^2 -2x +4x -8 = 4x
Combine like terms
x^2 +2x -8 = 4x
Subtract 4x from each side
x^2 +2x-4x -8 = 4x-4x
x^2 -2x-8 =0
Factor
What 2 numbers multiply to -8 and add to -2
-4*2 =-8
-4+2 = -2
(x-4) (x+2) =0
Using the zero product property
x-4+4 =0+4 x+2-2=0-2
x=4 x=-2
