What does the • stand for n the problem. -4 • 6

Multiplication

Step-by-step explanation:

simple form:

-4 x 6

-4 TIMES 6

therefore -4•6

it stands for x or multiply

Step-by-step explanation:

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

- "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."
