Ryan is going to the state fair. it costs $8 to enter and $0.75 for each ride ticket. Which equation describes the relationship between the total cost, c, and the number of ride tickets he purchased, t? the choices are
t = 0.75c + 8
t = 0.75c - 8c
c = 0.75t + 8
c = 0.75t - 8

the third one down

Step-by-step explanation:

c=0.75t+8

Step-by-step explanation:

the slope is .75 bc that's the cost per ride, and the +8 is the automatic cost of the ticket

43

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."
