Verify solution that of each the given function is a differential equation. dy" - y = 0, y. e) =é , yzft) = coshe - 2 y" + 2y'- 3y = 0, y, t = 83 kh) = e* 13 y" + 4y+3y=t, /, (t) = +/3 k (t) = 6 + /3

d is correct

step-by-step explanation:

.

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 )

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
