a circle is graphed on a coordinate grid and tgen reflected across the y-axis. if the center of the original circle was located at (x, y). which ordered pair represents the center of the new circle after the transformation

The new center is the point (-x, y)

Step-by-step explanation:

When you reflect a point across the y-axis, the x-coordinate changes to its opposite (additive inverse).

See the attached image for an example.

The circle on the right has center (3, 1).  When reflected across the y-axis, the reflected center is (-3, 1).

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer is c

step-by-step explanation:

81/12=324/x
