4. an automobile dealership received 11 cars that needed to be detailed. if the
service staff took 2 1/2
hours to detail the automobiles, how long did each car
take?

11 cars =21/2 hours

Convert 21/2 hours to minutes

60minutes =1hour

2.5 hours =150mins

11cars=150 mins

1 car =1/11×150mins=

150/11=13 7/11mins

7/11to seconds =60 seconds =1minutes

7/11×60secs =38secs

Answer =1car =13mins 38 secs

Step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
