Jerry started doing sit-ups every day. the first day he did 13 sit-ups. every day after that he did 2 more sit-ups than he had done the previous day. today jerry did 29 sit-ups. write an equation that could be solved to find the number of days jerry has been doing sit-ups, not counting the first day. let  n  represent the number of days.

an equation that can jerry to find the number of days he has been doing sit-ups is given by

An equation that can help Jerry to find the number of days he has been doing sit-ups is  

Step-by-step explanation:

First day = 13

Second day =  first day + 2 = 13 +2 =15

Third day  =  second day + 2 =  17

Fourth day = Third day +2  = 19

So,

13 , 15 , 17, 19, 21, 23 ...........

The common difference is 2

By using arithmetic series

where

is the number of sit-ups done on the nth day

n is  number of the days

d is the difference

Now

stop cheating

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
