Which answer is closest to the true value of the expression:
(9.1 x 10⁴)(1.1 x10^{-5})(log10^{-13})(1000)
(a) 1.3
(b) 13000
(c) -13000
(d) 1.3 x 10^{-11}
can anyone explain this one?

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

the first one, all those points on the line just make a strait line.
