Answer:
14. yes
15. no
16. (a) yes; (b) no; (c) -2
Step-by-step explanation:
14. Try the value and see if the result is true:
3·2 -7 < 2 ⇒ -1 < 2 . . . . TRUE
h = 2 is a solution
__
15. Try the value and see if the result is true:
-12 +8 ≥ -12/4 ⇒ -4 ≥ -3 . . . . FALSE
q = -12 is not a solution
__
16. The inequalities can be solved for the solution set.
-2x < 10
x > -5 . . . . . divide by -2
and
-6 < -2x
3 > x . . . . . divide by -2
So, the solution set is ...
-5 < x < 3
a) x = 0 is a solution
b) x = 4 is not a solution
c) x = -2 is a solution
