Spring Break is almost here! You and your friends want to go to the inner tubing hill at Keystone. The cost (y) for 1 person (x) is $35, the cost for 4 people (x) is $140. Write a linear equation that represents the cost of tubing. How much would it cost to rent 6 tubes?

$844

$6

$211

$210

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

- "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."

exactly you go it
