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)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
