Answer 8

yes, (d,e) is how you should interpret the numbers in the answer choices for the first question.

For the second question, the choice you made is incorrect.

I will help you work through the 3rd one if you show me what you have tried, or explain what it is that you don't understand about what to do.

Answer 9

For the second question, you chose \[y=3x\]\[3x-y=0\]as a system which has no solutions. What about \((0,0)\), does that satisfy both equations? If so, that system has a solution.

if you combine the equations in a system, and end up with a falsehood, that means the system has no solutions.

For example:

\[x+y = 1\]\[-x-y = 2\]Add those two equations together and you get \[x+y +(-x) + (-y) = 1+2\]\[0 = 3\]
No solution there.

A system of two linear equations such as these with no solution means that the equations describe parallel lines. Solutions are the points at which all the equations in a system intersect.
