7. Quadrilateral WXYZ with vertices W-1, 1),
X(2,-3), Y(O.-6), and Z(-2,-5): x= -3

Step-by-step explanation:

As given in the picture attached,

Coordinates of W → (-1, 1)

Coordinates of X → (2, -3)

Coordinates of Y → (0, -6)

Coordinates of Z → (-2, -5)

By reflecting these points across x = -3, distance between original points to the line of reflection and distance between the image points and line of reflection will be equal.

Coordinates of W' → (-5, 1)

Coordinates of Y' → (0, 0)

Coordinates of Z' → (-4, -5)

Coordinates of X' → (-8, -3)

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
