I'm just not sure about the interval notation and how you represent it on the number axis.
Find all values of x satisfying the inequalities. Present your answer using the interval notation and illustrate it with the help of the number axis.
Hey guys.
I just wanted to know if I'm on the right track with these questions.
a) (x - 1) (2x + 3) > 0
answer: x > 1 , x > - 1.5
b) |7 + 2x| >/_ 3
answer: x>/_ 3 (x is greater than or equal to 3)
c) |2x - 7| </_ 3x - 10
answer: x >/_ -2 or x >/_ -5 (x is greater than or equal to -2 or x is greater than or equal to -5)
(Apologies for the greater than / equal to signs - I didn't know how to in put them. The underscore (_) represents the equal to sign)
a) seems to be resolved
b) for this one please remember the rule or
following the rule

or are your solutions
c) similar situation but remember the rule
