Are quadrilaterals abcd and efgh similar?
• no quadrilaterals abcd and efgh are not similar because their corresponding segments are not proportional
yes, quadrilaterals abcd and efgh are similar because a translation of (x + 3y + 3) and a dilation by the scale factor of 2 from point a map quadnlateral abcd onto
efgh
no quadrilaterals abcd and efgh are not similar because their corresponding angles are not congruent,
yes quadrilaterals abcd and efgh are similar because a translation of (x + 2 y + 2) and a dilation by the scale factor of 2 from point d' map quadrilateral abcd onto
efgh

answer: need picture of problem

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."

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
