Step-by-step explanation:
Answer:
- Using the y-axis to represent pounds, and the x-axis to represent kilograms, the graph is straight line going through the origin with a slope of 2.2 lbs/kg.
Explanation:
A constant conversion factor, such as 1 kg 2.2 lb, means that the two units are in direct proportion; thus the graph is a straight line that goes through the origin.
The conversion factor also gives the slope of the line.
Depending on which axis you choose for either unit the slope may be 2.2 pounds per kilogram, or 1/2.2 kilogram per pound.
When you use the y-axis for pounds and the x-axis for kilograms then the relationship is:
In that case, the slope is 2.2 pounds per kilogram.
Answer:
No real roots
Step-by-step explanation:
The given equations are:
We make y the subject in the first equation to get
We substitute into the second expression to get:
We expand to get:
Multiply through by 4 to get:
The discriminant is given by 
Since the discriminant is less than zero, the two curves never intersects.
Therefore the system has no real roots
