6. An air conditioning repair service call costs $75 per hour plus a flat fee trip charge of $25. If the situation can be represented by the function r(h) = 75h + 25, what do the variables represent and which is the dependent

variable?

a. The repair time h depends on the repair charges r in hours.

b. The repair charges h depends on the repair timer in hours.

c. The repair charges r depends on the repair time h in hours.

d. The repair time r depends on the repair time hin hours

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.

Step-by-step explanation:

Repair-service call  -  $75 /hour

Flat fee trip-charge  -  $25

The function representing this situation: r(h) = 75h + 25

(A) Which is the dependent variable?

The dependent variable is the one whose value is to be gotten from the relationship between or among the values of other variables in the function. It usually appears at the left hand side of the equation. In this case, it is r(h).

(B) What do the variables represent?

The variables here - the algebra that can attain various values - are r and h.

r = total repair charges

h = repair time in hours [hence, if h = 1, repair time is 1 hour]

These are the two variables in this function.

r(h) now means repair charges in hours

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.

- "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."

the median is   36 orr sum like dat
