If r<0, which of the following must be true? Options:
A) –100 < r < 100
B) r ≤ –1
C) r ≤ 1
D) r^2 ≥ 1/4
E) –100 < r < 0
r is a negative number.   A. –100 &lt; r &lt; 100r can be a negative number less than -100   B. r ≤ –1r can be a fraction, in which case it would be greater than -1   C. r ≤ 1must be true since 1 is positive and r is negative   D. r^2 ≥ 1/4not true if r is a negative fraction like -1/5   E. –100 &lt; r &lt; 0r can be a negative number less than -100=r ≤ 1
