Can you help me i really don't understand math at all If r = 12.5 and s = |−13|, which of the following inequalities is not true?

A)r ≠ s
B)r < s
C)r ≥ s
D)r ≤ s

Which is true about the solution to the system of inequalities shown? y > 3x + 1 y < 3x – 3 only values that satisfy y > 3x + 1 are solutions. only values that satisfy y < 3x – 3 are solutions. values that satisfy either y > 3x + 1 or y < 3x – 3 are solutions. there are no solutions.
