Answer:
W1 = ( -75, 20, 1 , 0 )
W2 = ( 25, -7 , 0, 1 )
Step-by-step explanation:
attached below is the remaining part of the solution
for a homogenous system of equation ; Ax = 0
x1 + 4x2 -5x3 + 3x4 = 0
-x2 + 20x3 -7x4 = 0 note: x3 and x4 are free variables
we can take x3 = 0 and x4 = 1 , hence ; x2 = -7
∴ x1 - 28 + 3 = 0 = x1 = 25
W2 = ( x1 ,x2, x3, x4 ) = ( 25, -7 , 0, 1 )
now lets take x3 = 1 and x4 = 0 hence x2 = 20 , x1 = -75
∴ W1 = ( x1 , x2 , x3, x4 ) = ( -75, 20, 1 , 0 )
Answer:
Point (0,0)
Step-by-step explanation:
Given the inequality y > 12x – 11.
We will check which of the given options will be applied for the inequality
A) (1,0)
Substitute with x = 1 and y = 0
0 > 12*1 - 11
0 > 1 ⇒ Wrong
So, Point (1,0) is not part of the solution of the inequality.
B) (3,2)
Substitute with x = 3 and y = 2
2 > 12*3 - 11
0 > 25 ⇒ Wrong
So, Point (3,2) is not part of the solution of the inequality.
C) (1,1)
Substitute with x = 1 and y = 1
1 > 12*1 - 11
1 > 1 ⇒ Wrong
So, Point (1,1) is not part of the solution of the inequality.
D) (0,0)
Substitute with x = 1 and y = 0
0 > 12*0 - 11
0 > -11 ⇒ True
So, Point (0,0) is part of the solution of the inequality.
Also, see the attached figure which represents the given inequality
The shaded area represents the solution of the inequality, and we can note that point (0,0) is part of the solution of the inequality
