A figure was transformed on a coordinate grid using the rule (x, y) - (-x, -y). Which of the following describes this transformation? F A reflection across the x-axis

G A reflection across the y-axis

H A 90 degrees clockwise rotation about the origin

J A 180 degrees clockwise rotation about the origin

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

40 minutes

step-by-step explanation:

add the time and multiply by 2

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
