I NEED HELP PLEASE, THANK YOU! :)

Suppose the point B(2,8) is reflected across the x-axis and then translated according to the rule (x, y)→(y, x+4). What are the coordinates of B''? Show your work and explain.

====================================================

Work Shown:

B = (2,8) is the starting point

B' = (2,-8) after reflecting over the x axis. The y coordinate flips from positive to negative. The x coordinate stays where it is.

----------

(2,-8) is in the form (x,y) with x = 2 and y = -8

This shows (2,-8) translating or shifting to (-8,6) to get to the location for B''

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
