Choice A is the correct answer. Intersection of sets.

1. First: $6 - 2x \leq 4 \rightarrow -2x \leq -2 \rightarrow x \geq 1$
2. Second: $x \geq -3$
3. Combine: $x \geq 1$ AND $x \geq -3$. The intersection is $x \geq 1$ (since 1 is greater than -3).

?�� Strategic Tip: If both are "greater than", the intersection is "greater than the larger number".

Choice B is incorrect.Choice C is incorrect because it is the union, not intersection. Choice D is incorrect.
