Question

warm up: which three go together: arrows
which three go together? why do they go together?
a
number line with -10 to 10, two right - pointing arrows
b
number line with -10 to 10, one left - pointing and one right - pointing arrow
c
number line with -10 to 10, one left - pointing and one right - pointing arrow
d
number line with -10 to 10, two left - pointing arrows

Explanation:

Step1: Analyze Arrow Directions and Lengths

Check the direction (left/right) and length (number of units covered) of each arrow in the options. For three to go together, they should have consistent direction and length relationships (e.g., same direction and length, or opposite directions with complementary lengths).

Step2: Compare Option C

In option C, the arrows: one right - pointing (positive direction), one left - pointing (negative direction), and another right - pointing. Wait, re - evaluate. Wait, actually, looking at the number lines, in option C, the arrows likely have consistent properties (e.g., the right - pointing arrows and left - pointing arrow have lengths that are related, maybe representing additive inverses or same - magnitude opposite - direction, and another same - direction). Wait, more accurately, option C's arrows: let's see the number line. The right - pointing arrows and the left - pointing arrow in C: maybe the lengths are such that two right - pointing and one left - pointing, but actually, the key is that in option C, the arrows have consistent direction - length relationships. Wait, no, let's re - check. The correct group is C because the arrows in C have directions and lengths that are consistent (e.g., the right - pointing arrows have certain lengths, and the left - pointing arrow has a length that is related, maybe same magnitude as one of the right - pointing, or the set has a pattern of direction and length). Alternatively, maybe the arrows in C have the same "type" of movement (e.g., two right - pointing and one left - pointing with lengths that are complementary, or all having the same length in their respective directions). After analyzing, option C's arrows go together because their directions and lengths follow a consistent pattern (e.g., the right - pointing arrows and left - pointing arrow have lengths that are related, maybe representing positive and negative movements with consistent magnitudes).

Answer:

C (the option labeled C)
