4x + 3y= 12
4x + 3*0= 12, x-int= 3
4*0 + 3y= 12, y-int= 4
Step-by-step explanation:

First, let's move the
to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:

From here, since the coefficient of the
term is
, we know the square will be
(since
it's half of
).
To complete this square, we will need to add
to both sides of the equation:



Now we can take the square root of both sides to figure out the solutions to
:


6x17=100 so you basically multiply 6x17 which would be 100
16/ 2.10 = 7.6 ounces per $1
20/ 3.15 = 6.3 ounces per $1
So which do you think?
