Question

Write an expression in words that describes the set of numbers given by the interval (–6, 7).

A. All real numbers greater than –6 and less than 7
B. All real numbers less than –6 and greater than 7
C. All real numbers greater than or equal to –6 and less than or equal to 7
D. All real numbers less than or equal to –6 and greater than or equal to 7

Answer 1

"A" in the true answer

Explanation:

Answer 2

For this case we have the following interval:

`(- 6, 7)`

The equivalent expression for this interval is given by:

`-6 <x <7`

Therefore, we have the following inequations:

`x> -6`

`x <7`

From where, we can conclude:

All real numbers greater than -6 and less than 7

Answer:

An expression in words that describes the set of numbers given by the interval (-6, 7) is:

A. All real numbers greater than -6 and less than 7
