X < 2 is the solution to which of the following compound inequalities?
1 answer:
Answer:
see below
Step-by-step explanation:
It works well to think about what these compound inequalities mean. One way to do that is to graph them, or to imagine what the graph of them looks like.
Since the result is a single inequality (x < 2), the compound will be "and" with x < 2 being more restrictive, or will be "or" with x < 2 being the least restrictive of completely overlapping inequalities.
Of the choices offered, C is the one of interest.
_____
<em>Comment on other choices</em>
A has all real numbers as solutions except in the range 2 ≤ x ≤ 3.
B has no solutions
C simplifies to x < 2 . . . . the one we want
D simplifies to x < 4
