4 0

Answer:

A. 12.5 miles per hour B. 0.36 hours

Step-by-step explanation:

3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour

next, take 4.5 and divide by the new mph 12.5 from your previous answer.

4.5/12.5=0.36 hours

The TV repairman charges $40 to come out to your house and check the TV
sergeinik [125]

Answer:

The equation to find the cost of repairing a TV is:

y = 25x + 40

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope or rate of change and b is the y-intercept

Given that the TV chairman charges $40 to come out to your house and check the TV  plus $25 per hour of labor.

It means $40 is the y-intercept because it represents the starting point/condition of the repairman.

Let 'x' be the number of hours and y be the cost.

The rate of change = 25$ per hour of labor

  • The rate of change can also be termed as the slope.

Thus, m = 25

Hence, the slope-intercept form of the line equation becomes

y = mx+b

substituting m = 25 and b=40

y = 25x + 40

Therefore, the equation to find the cost of repairing a TV is:

y = 25x + 40

Validation:

y = 25x + 40

putting x = 1 to determine the cost if labor works for 1 hour.

y = 25(1) + 40 = $65

putting x = 2 to determine the cost if labor works for 2 hours.

y = 25(2) + 40 = $95
