To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:
Where is the slope and
is the y-intercept.
3. Then, you have that the slope of the function is:
Therefore, the answer is:
Answer:
Step-by-step explanation:
From the question we are told that
5% solution of dextrose sugar in water
20% solution of dextrose in
100 milliliters of distilled water water
Generally in mathematically solving we call A the amount of D20W added
Since 20% of dextrose is needed
Total quantity after addition (100+x)
for DW5% total solution is
Mathematically
Therefore the required quantity
