At a real estate​ agency, an agent sold a house for ​$379,000. The commission rate is ​7.5% for the real estate agency and the commission rate for the agent is ​30% of the amount the real estate agency gets. How much did the agency make on the​ house?

tube or goog would be a great resource to with that question

- "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."
