Which table shows a proportional relationship between x and y me and earn 20 points

the answer is A

Step-by-step explanation:

i said a because

5×5=25

6×5=30

8×5=40

the answer is "d"

Step-by-step explanation:

the answer is d because if you add 10 to 25 you will get 35 and same for the rest if you add 10 to x you will get the answer for y

the answer to this question is 3/19

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
