2.7(<=)b+5

a. b(>=)7.7
b. b(>=)-2.3
c. b(<=)2.3
d. b(<=)-7.7
Answered by Damon
2.7 </= b + 5

-2.3 </= b

or
b >/= -2.3 which is c
==========================
now check that
if b = -2.3 , the original must be true
2.7 = b+5 ???
2.7 </= -2.3 + 5 ???
2.7 = 2.7 yes
if b = -2 should also be true
2.7 < -2 + 5
2.7 < 3 yes
