Answer: If a linear system has no solution, the two lines are parallel. If it has one solution, the lines will intersect at exactly one point because they have different slopes.
Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
First step is to calculate x return on investment
x return on investment = $600 - $500
x return on investment= $100
Second step is to calculate y return on investment
y return on investment= $900 - $750
y return on investment= $150
Now let determine the ratio of return on investment from company x to that from company y
Using this formula
Ratio of return on investment=x return on investment/y return on investment
Let plug in the formula
Ratio of return on investment=100/150
Ratio of return on investment=2/3
Ratio of return on investment=2:3
Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
