  • $ax + by + c = 0$ and $dx + ey + f = 0$ (correct)
  • $ax^2 + by^2 + c = 0$ and $dx^2 + ey^2 + f = 0$
  • $ax + by = c$ and $dx + ey = f$

    • What does it mean if a pair of linear equations in one variable has no solution?

  • The lines represented by the equations intersect at exactly two points.

    Study Notes

    Linear Equations in One Variable

    • A pair of linear equations in one variable typically takes the form: ax + b = 0 and cx + d = 0, where a, b, c, and d are constants.

    • If a pair of linear equations in one variable has no solution, it indicates that the lines represented by the equations are parallel and do not intersect, meaning there is no common value for x that satisfies both equations.

    • A condition for a pair of linear equations in one variable to have infinitely many solutions is when the equations are equivalent, meaning they represent the same line, derived from consistent coefficients where a/c = b/d.

    Rise of Nationalism in Europe

    • The rise of nationalism in Europe was triggered by the events of the French Revolution, which challenged old monarchies and inspired the idea of popular sovereignty.

    • A major factor contributing to the growth of nationalism was the spread of Enlightenment ideas, emphasizing liberty, equality, and the rights of individuals, fostering a sense of identity among people within nation-states.

    • A common goal of nationalist movements in Europe included the unification of culturally similar groups into independent nation-states, aspiring to establish self-governance free from foreign rule or domination.
