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

Identify Meaning: Identify the meaning of the set notation. The set {x | x ≥ -15} reads as ＂the set of all x such that x is greater than or equal to -15.＂Match Notation: Match the set notation to the correct choice. The phrase ＂greater than or equal to -15＂ corresponds to all numbers on the number line that are -15 or to the right of -15.Eliminate Incorrect Choices: Eliminate incorrect choices based on the set notation. (A) Incorrect because it says ＂greater than＂ but does not include -15 itself. (C) Incorrect because it only includes the number -15 and not all numbers greater than it. (D) Incorrect because it says ＂less than -15＂ which is the opposite of what the set notation specifies.Confirm Correct Choice: Confirm the correct choice. (B) is the correct choice because it includes all numbers that are -15 and all numbers greater than -15, which matches the set notation {x | x ≥ -15}.

-15

\newline

(B)all numbers greater than or equal to

-15

\newline

(C)all numbers equal to

-15

\newline

(D)all numbers less than

Identify Meaning: Identify the meaning of the set notation. $\newline$ The set ${x | x \geq -15}$ reads as ＂the set of all $x$ such that $x$ is greater than or equal to $-15$ .＂
Match Notation: Match the set notation to the correct choice. $\newline$ The phrase ＂greater than or equal to $-15$ ＂ corresponds to all numbers on the number line that are $-15$ or to the right of $-15$ .
Eliminate Incorrect Choices: Eliminate incorrect choices based on the set notation. $\newline$ (A) Incorrect because it says ＂greater than＂ but does not include $-15$ itself. $\newline$ (C) Incorrect because it only includes the number $-15$ and not all numbers greater than it. $\newline$ (D) Incorrect because it says ＂less than $-15$ ＂ which is the opposite of what the set notation specifies.
Confirm Correct Choice: Confirm the correct choice. $\newline$ (B) is the correct choice because it includes all numbers that are $-15$ and all numbers greater than $-15$ , which matches the set notation $\{x | x \geq -15\}$ .
