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)

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
