What does the set {x | x ≥ -15} represent? Choices: (A)all numbers less than -15 (B)all numbers greater than -15 (C)all numbers greater than or equal to -15 (D)all numbers equal to -15

Set Description: The set {x | x ≥ -15} is read as ＂the set of all x such that x is greater than or equal to -15.＂ This is a description of a range of numbers on the number line.Inequality Consideration: To understand what this set represents, we need to consider the inequality x ≥ -15. This inequality includes all numbers that are greater than -15 as well as the number -15 itself.Inequality Inclusion: The inequality does not only include numbers greater than -15, but also the number -15, as indicated by the 'greater than or equal to' symbol (≥). Therefore, it cannot represent only numbers greater than -15 or only numbers equal to -15.Correct Representation: Given the choices provided, the correct representation of the set {x | x ≥ -15} is all numbers greater than or equal to -15, which corresponds to choice (C).

Set Description: The set ${x | x \geq -15}$ is read as ＂the set of all $x$ such that $x$ is greater than or equal to $-15$ .＂ This is a description of a range of numbers on the number line.
Inequality Consideration: To understand what this set represents, we need to consider the inequality $x \geq -15$ . This inequality includes all numbers that are greater than $-15$ as well as the number $-15$ itself.
Inequality Inclusion: The inequality does not only include numbers greater than $-15$ , but also the number $-15$ , as indicated by the 'greater than or equal to' symbol ( $\geq$ ). Therefore, it cannot represent only numbers greater than $-15$ or only numbers equal to $-15$ .
Correct Representation: Given the choices provided, the correct representation of the set ${x | x \geq -15}$ is all numbers greater than or equal to $-15$ , which corresponds to choice (C).
