Write a word problem that represents the algebraic expression: 5x+40 A) A plumber makes $40 an hour plus a $5 flat rate per job.

B) A cowboy pays$40 to enter a rodeo but makes $5 per entry

C) A waitress makes 5% tips and $40 dollars an hour.

D) An electrician charges $40 for showing up to a job plus $5 per hour spent on the job.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

- "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."
