David ran the yard dash in 7.2 seconds and won the event justin came in second with a time of 8.1 seconds how much better was davids time than justins

0.9 seconds

Step-by-step explanation:

Since Justin came in slower, you would put his time first:

8.1 - 7.2

Doing that gets you 0.9

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 )

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
