Answer:
C
Step-by-step explanation:
Recall that whenever our simplification of a linear equation ends in a true statement, then our linear equation has infinitely many solutions.
Therefore, our answer is C.
In general:
- If we get a true statement (e.g. x = x, 6 = 6, etc.), then our linear equation has infinitely many solutions.
- If we get a false statement (e.g. 0 = 1, 7 = 2, etc.), then our linear equation has no solution.
- And if we get a variable equal to a value (x = 2, x = 7/2, etc.), then our linear equation has exactly one solution.
This is because if we get a true statement, then this implies that the two linear equations are the exact same line.
If we get a false statement, this implies that the two equations are two distinct parallel lines: they will never intersect.
Lastly, if we get a variable equal to a value, this implies that the two equations are distinct and non-parallel: they will intersect at one point.

Step-by-step explanation:
These models show the electron structures of two different nonmetal elements.
Which element is likely more reactive, and why?
Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.
Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.
Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.
Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
