Answer:

D (8z-4)*(-7)

Step-by-step explanation:

Given:

-56z+28

D (8z-4)*(-7)

-56z+28

Therefore, option D is the equivalent expression

Finding the equivalent expression by solving each option and eliminating the wrong option

A 1/2*(-28z+14)

=-28z+14/2

=-14z+7

B (-1.4z+0.7) /* 40

Two signs ( division and multiplication)

Using multiplication,we have

-56z+28

Using division, we have

0.035z + 0.0175

C (14-7z)*(-4)

-56+28z

D (8z-4)*(-7)

-56z+28

E -2(-28z-14)

56z+28

The answer is D because the y intercept is a positve one, and when you find the slope, it is -3. To find the slope, you can either pick two points on the graph and do y1 -y2 over x1-x2, or you can count the slope on the graph.

The median and mean can only have one value for a given data set so the answer is false
