Answer:
11 > (w- 4)
y < 3
5 + 9 < 5.9
So these are the phrases which are inequalities.
Answer:
It is 300 miles.
Step-by-step explanation:
60 + 0.50x = 30 + 0.60x
x = 300
Answer:
n= 9
Step-by-step explanation:
just plug in 9...
9+1= 10
10/10=1
Answer:
Therefore the particular solution of the given differential equation is

Step-by-step explanation:
The given ordinary differential equation is

If y₁(x) =x² is a solution of ODE then it will be satisfy the ODE
y₁'(x)= 2x and y₁"(x)=2
Putting the value of y₁'(x) and y₁"(x) in x²y"-3xy'+4y=0 we get
x².2-3x.2x+4x²= 2x²-6x²+4x²=0
Therefore y₁(x) is a solution of the given differential equation.
Again,
y₂(x) =(x²ln x ) is a solution of ODE then it will be satisfy the ODE.


= 3+2 ln x
Putting the value of y₂'(x) and y₂"(x) in x²y"-3xy'+4y=0 we get
=0
Therefore y₂(x) is a solution of the given differential equation.
The wronskian of y₁(x) and y₂(x) is


=x²(2x ln x+x)-x²ln x(2x)
=2x³ ln x +x³ - 2x³ln x
=x³≠0
Here 
The particular solution is


Let ln x =u 



Therefore the particular solution of the given differential equation is
