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.
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)
