Darnells car used 8 gallons to travel 340. miles after a machanic worked on the car it used 7 gallons of gasoline to travel 350 miles if the price of gasoline was approximately $4.00 per gallon how much less to the nearest cent per mile did it cost to run the car after the mechanic worked on it

 What we are going to do for this case is find the cost for each case:

 Cost to run the car before the mechanic worked on it:

 Cost to run the car after the mechanic worked on it:

 The difference between both cases is:

 It cost to run the car after the mechanic worked on it 0.01 $ / mile less than before the mechanic worked on it.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
