Answer:
8
Step-by-step explanation:
40 grouped into 5 = 40/5 = 8
The line equation is given by

where <em>m </em>is the slope and <em>b </em>is the interception with <em>Y-axis</em>
Answer:
D
Step-by-step explanation:
the rest of them have 2 Y for 1 X
First look for the fundamental solutions by solving the homogeneous version of the ODE:

The characteristic equation is

with roots
and
, giving the two solutions
and
.
For the non-homogeneous version, you can exploit the superposition principle and consider one term from the right side at a time.

Assume the ansatz solution,



(You could include a constant term <em>f</em> here, but it would get absorbed by the first solution
anyway.)
Substitute these into the ODE:




is already accounted for, so assume an ansatz of the form



Substitute into the ODE:





Assume an ansatz solution



Substitute into the ODE:



So, the general solution of the original ODE is
