Question

How would you write (-2,7] as an inequality?

A) x > -2 and x ≤ 7
B) x < -2 or x ≥ 7
C) x ≥ -2 and x < 7
D) x > -2 or x ≤ 7

Answer 1

To write (-2,7] as an inequality, use the symbols > and ≤ to represent numbers greater than -2 and less than or equal to 7, respectively.

Step-by-step explanation:

To write (-2,7] as an inequality, we need to break it down into two parts.

The first part, (-2, represents numbers greater than -2, so we can use the symbol > to represent this. The second part, 7], represents numbers less than or equal to 7, so we can use the symbol ≤ to represent this.

Combining both parts, the inequality is x > -2 and x ≤ 7.
