Write the solution to the given inequality in interval notation.
Mazyrski [523]

Answer:

(-\infty,4)\cup (5,\infty)

Step-by-step explanation:

From the number line, the solution to the inequality is x<4 or x>5.

We can write x<4 in interval notation as (-∞,4) and x>5 as (5,∞).

The "or" represents the union of the two intervals.

Therefore the solution to the given inequality in interval notation is:

(-\infty,4)\cup (5,\infty)

The third choice is the correct answer.
