Triangle abc is shown below: triangle abc is shown. a is at 2, 1. b is at negative 1, 4. c is at 3, 7. if triangle abc is reflected over the x-axis, which of the following shows the coordinates for point c'?
(−3, 7)

(3, 7)

(−3, −7)

(3, −7)

Reflecting across the Y axis would make all the points on the triangle the same distance from the Y axis, just on the opposite side.

Point B is at X = -1, so when reflected across the Y axis would be at X = 1

The Y value would remain the same.

The new location for B would be (1,4)

please add graph for next time could help more

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
