Answer:

See below.

Step-by-step explanation:

There is an infinite number of values of x that make each answer true. The problem is asking "for which value" with value in the singular, so I thought it was asking to choose one answer from several, and only one was correct.

1a.

Any number between 8 and 9 is correct.

Examples: 8.1, 8.01, 8.2, 8.3, 8.4, 8.9, 8.95, etc.

As I wrote above, there is an infinite number of correct answers.

1b.

Examples: 8.91, 8.92, 8.93, 8.99, 8.905, 8.97, etc.

Answer:

Assuming that inequalities are a valid answer for this question:

1a. 8 < x < 9

1b. 8.9 < x < 9.1

Step-by-step explanation:

Really, there's no exact answer. For example, on 1a, it could be 8.1, 8.11, 8.2, 8.99999, etc. Inequalities are used to denote the fact that the x value can be anywhere between two values. In 1a, x is between 8 and 9, and in 2a, x is between 8.9 and 9.1.
