Diana creates a graph for the amount of money she earns, y, for working x hours. The graph contains the points (34,408), (40,480), and (46,588).

Which TWO statements must be TRUE?
A. The last point does not show a proportional relationship with the others because the hourly rate of pay is $18 per hour.
B. The points do not show a proportional relationship because the difference between the y-coordinates is not the same.
C. The first two points show a proportional relationship with each other because the hourly rate of pay is $12 per hour
D. All of the points show a proportional relationship because the amount of hourly pay is a whole number
E. All points show a proportional relationship because the difference between the x-coordinates is 6

Evaluate 3z- 3 when z=7

a 34
b 21
c 18

Answers

Answer: C (18)

Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.

Answer:

C

Step-by-step explanation:

Since z = 7 the equation would be 3(7) - 3

You would multiply 3 with 7 and get 21

Then you would subtract 3 from 21 and get 18
