Find how many quarts of 5% butterfat milk and 2% butterfat milk should be mixed to yield 45 quarts of 3% butterfat milk. The mixture should contain quarts of the 5% butterfat milk.

It would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.

Step-by-step explanation:

Let the number of 5% quarts = x

Let the number of 2% quarts = y

x+y=45

y=45-x

(.05)x+(.02)y=(0.03)45

5x+2y=102

5x+2(45-x)=102

5x+90-2x=102

3x=12

x=4

y=45-x=45-4=41

So it would take 4 quarts of 5% buttermilk and 41 quarts of 2% buttermilk to make 45 quarts of 3% buttermilk.

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
