Simplify the function f(x)= 1/2 (27) 2x/3. then determine the key aspects of the function

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

- "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."

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
