    The interval notation that represents the possible values of x is:
    (-9, 1) U [27, ∞)

    How to represent the given values of x in interval notation?

    First, we know that x can be any real value between -9 and 1, then we can represent it by the inequality:
    -9 < x < 1
    Or, writing this in interval notation we get:
    (-9, 1)
    Then we know that x can also be greater than or equal to 27, then:
    x ≥ 27
    Then this can be represented as:
    [27, ∞)
    Now we can write the union of the two intervals as:
    (-9, 1) U [27, ∞)
    The interval notation that represents the possible values of x is:
    (-9, 1) U [27, ∞)
