Jessica rented a truck to move into another apartment. The rental charge is %140 per day plus $0.35 per mile. Write an equation to determine x, the number of miles she can drive the truck if the cost is y.

- "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."

its 50 miles away from the starting point

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
