Question

How do you write(−∞,8),(10,∞),as an inequality?

A. x < 8 or x > 10
B. x < 10 or x > 8
C. x < 8 and x > 10
D. x < 10 and x > 8

Answer 1

(−∞,8),(10,∞) is equal to x < 8 οr x > 10

Answer 2

The answer is the option A

`x< 8` or
`x>10`

Explanation:

we know that

The interval -----> (-∞,8)

Is all real numbers less than
`8`

`x<8`

The interval -----> (10,∞)

Is all real numbers greater than
`10`

`x>10`

The expression (-∞,8) U (10,∞) represent the inequality

`x< 8` or
`x>10`
