Check the boxes which make the statement correct: If the det()=0 then A. Given any there is one and only one which will satisfy the equation. B. Some values of (such as =0 ) will allow more than one to satisfy the equation. C. Given any there is one and only one which will satisfy the equation. D. Some values of will have no values of which will satisfy the equation. E. There is no value of which satisfies the equation when =0.

- "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."

answer: x=3 and y=4
