Solve the system. 7w + 7x + 7y + 7z = -7 2w + 2x + 2y + 5z = -1 w + 2x + y + 2z = 6 If the system has one solution, enter it below. If the system has infinitely many solutions, enter the solution for which the value of each arbitrary variable is set to 9. If the system has no solution, enter "N" for each variable. w= x= y= z=
Find the angle between the planes 3x+10y = 17 and 7x + 7y + 3z = - 10. The radian measure of the acute angle is 0= (Round to the nearest thousandth.)
Let y be a differentiable function such that y' – 7y = 7, where y' is the first derivative of y. Define addition yı y2 = yı + y2 + 1 and scalar multiplication c Oyı = cyı + c – 1. Let V be the set of all differentiable functions that solve y' – 7y = 7. Note that these functions fit the form y = ket – 1. Determine if V is a vector space.

Solve the system of linear congruences: 7x = 1 mod 8, 7x = 1 mod 13, 7x = 1 mod 17
I'm trying to solve this problem: Let Y ~ Bin (8, 0.5) Find E(7Y - 36Y2 + 8Y -4) I know how to simplify all the terms except for E(7Y), so what I have so far is: E(7Y) - 36V(Y) + 8E(Y) - 4. How do I simplify E(7Y) so that I can solve the problem?
2) Solve with UC superposition. y" - 8y' + 7y = e2x + 2x
1) Solve with reduction of order. y" + 7y' - 18y = ex + e2x
