Answer: las option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope of the line and b is the y-intercept.
Then function given in the problem has the form:
Where:
m=3
b=-2
Therefore, it is a linear function.
By definition, the domain of the linear functions that are not bounded, is all the Real numbers.
Therefore, the answer is:
<em> {x | x is a real number}</em>
We know that 20% of the first type of juice is pure fruit juice and 45% of second type of juice is pure fruit juice.
Now we have to make 30 pints of a mixture that is 35% pure.
Let x be the number of pints of first type of juice and y be the number of pints of second type of juice.
So, (Equation 1)
Since, 20% of x + 45% of y = 35.3% of 30
(Equation 2)
Solving equations 1 and 2,
we get y=18 and x=12.
So, 12 pints of first type of juice and 18 pints of second type of juice are used.
