1 - True. If a number is divisible by 12 it's divisible by 6 and thus by 3
2 - False. A rhombus needn't have square angles
3 - False. the second proposition is unrelated to the first one, and doesn't allow us to deduce that cats have fur.
4 - False - We cannot link the first and second proposition in any way to make the third
Answer:
<em>one</em><em> </em><em>solution</em><em> </em>
<em>no</em><em> </em><em>solution</em><em> </em>
<em>infinity</em><em> </em><em>solutions</em><em> </em>
Step-by-step explanation:
A: If the graphs of the equations intersect, then there is one solution that is true for both equations.
B; If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.
C; If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations

A-2: Project D.
b: Project A.
Not sure about a-1, hope I helped.
