The coordinates of a quadrilateral are (5, 8), (7, 10), (9, 12), and (11, 14). after a transformation, the sign of the x-coordinate and the sign of the y-coordinate for each ordered pair have changed. which type of transformation occurred? a) 180° rotation b) (x, y)→(x + 2, y + 2) c) reflection across the y-axis d) reflection across the x-axis

A

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y )

Under a reflection in the y- axis

a point (x, y ) → (- x, y )

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Since the sign of both coordinates have changed then the transformation is

A rotation of 180° → A

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

he has now walked a total of what?

if i know what this is maybe i can
