Solve the following problems by using the Variation of Parameters y′′− 8y′+ 16y = e^4x ln(x)

Solve the simultaneous equations: a) x + y = 7, 3x - 2y = 11 b) 7x - 2y = 1, 3x + 4y = 15?

Solve the simultaneous equations:a) x + y = 7, 3x - 2y = 11b) 7x - 2y = 1, 3x + 4y = 15

Solve the equation y'=5-8y with initial condition y'(0)=0

Solve the system of equations: x+y^2=6y x-2y=-5

3. Solve the following differential equations by using LaPlace transformation: 2x'' + 7x' + 3x =...

3. Solve the following differential equations by using LaPlace transformation: 2x'' + 7x' + 3x = 0; x(0) = 3, x'(0) = 0 x' + 2x = ?(t); x(0-) = 0 where ?(t) is a unit impulse input given in the LaPlace transform table.

Solve x′=x−8y, y′=x−3y, x(0)=2, y(0)=1

solve for |2x-5|>4x-1

2. Find the following derivative y=4x?

2. Find the following derivative y=4x? 3. Find any maximum or minimum values of the function y(x)=1+x/e4x. Use a sign chart or a second derivative test to verify the answer(s) you get is a max or min.

y'' - 8y = 4, y(1) = 9, y'(0) = 5

Use Kramer’s Rule to solve for x, y, and z from the following equations: 4x-7y+2z=4, 3x-11y+5z=3,...

Use Kramer’s Rule to solve for x, y, and z from the following equations: 4x-7y+2z=4, 3x-11y+5z=3, -9x+4y+3z=1. (Hint: Use Determinants)
