Answer: 6; 5

Step-by-step explanation:

Based on the questions, we set up two equations, let the x be the first number, and y be the second number.

x + y = 11

2x - y= 7

x = 11 - y              [Subtract y from both side]

2x - y = 7

2(11 - y) - y = 7    [Plug in 11-y for x, solve for y]

22 - 2y - y = 7  

22 - 3y = 7        

-3y = -15             [Subtract 22 from both side]

  y = 5

 

x + y = 11             [Plug in 5 for y, solve for x]

x + 5 = 11             [Subtract 5 from both side]

     x = 6

(10 pts) (a) (2 pts) What is the difference between an ordinary differential equation and an initial value problem? (b) (2 pts)
laiz [17]

Answer:

Step-by-step explanation:

(A) The difference between an ordinary differential equation and an initial value problem is that an initial value problem is a differential equation which has condition(s) for optimization, such as a given value of the function at some point in the domain.

(B) The difference between a particular solution and a general solution to an equation is that a particular solution is any specific figure that can satisfy the equation while a general solution is a statement that comprises all particular solutions of the equation.

(C) Example of a second order linear ODE:

M(t)Y"(t) + N(t)Y'(t) + O(t)Y(t) = K(t)

The equation will be homogeneous if K(t)=0 and heterogeneous if K(t)\neq 0

Example of a second order nonlinear ODE:

Y=-3K(Y){2}

(D) Example of a nonlinear fourth order ODE:

K^4(x) - \beta f [x, k(x)] = 0
