Answer:
Set equal to zero and solve for x
. The multiplicity of a root is the number of times the root appears.
x
=
−
1 (Multiplicity of 1
)
x
=
8 (Multiplicity of 1
)
x
=
−
2
5 (Multiplicity of 1
)
Step-by-step explanation:
"Bucket method"
.. (4)*(14%) + (x)*(8%) = (4 +x)*(10%) . . . . . liters and % are in each "bucket"
.. 56 +8x = 40 +10x . . . . . multiply by 100, eliminate parentheses
.. 16 = 2x . . . . . . . . . . . . . . add -40-8x, then divide by 2
.. 8 = x
8 liters of 8% lemonade should be added to make the mixture 10% lemon juice.
The denominator is the one on the bottom so 9 is the denominator the top is the numerator
