How do you copy and paste edmentum math equations on here that won't copy and paste?

Step-by-step explanation:

key, you can press [CTRL][C] to copy the answer or expression to local memory. You can then use [CTRL][V] to paste this copied item as often as you want in future calculations. For example, perhaps you’re using the distance formula to find the distance between two points. After entering and evaluating the expression for the first time, press

answer: a

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."
