Math 3410 summer 2 2019 midterm exam 1-evening pencil start each problem on a new page. write on a clean paper with a good pen or so its image is legible 1. for each of the differential equations below state its order and whether it is linear or nonlinear. if it is linear state whet her it is homogeneous or not a. py"-y+5 b. yiy c. ey cos(t)

x+14

step-by-step explanation:

2.56 is the width of the garden

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
