What condition renders this true, where S and T are sets?
daser333 [38]

Answer:

There are no sets S, T for which

S \cup T^c=S^c\cap T

holds

Step-by-step explanation:

Let the set A be

A=S\cup T^c

By de De Morgan's Law

A^c=S^c\cap ((T)^c)^c

But

((T)^c)^c=T

A^c=S^c\cap T

We conclude that

S \cup T^c=S^c\cap T\Rightarrow A=A^c

which is a contradiction because no set is equal to its complement.

makvit [3.9K]

Answer:

7

Step-by-step explanation:

Work with PEMDAS

(Subtracting a negative from a negative is the same thing as adding)

7-(-19)-18+(-19)+18

7-(-19)=26

-18+(-19)=-37

26-37+18= 7

Who knows the x and y values of<br> x+5y=-12<br> 5x+4y=24
musickatia [10]
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8

Suppose x and y are nonzero vectors in an inner product space. Show that x and y are orthogonal if and only if ||x+y|| = ||x-y||
harkovskaia [24]

Answer:

Step-by-step explanation:

Suppose x and y are nonzero vectors in an inner product space.

Let us assume that x and y are orthogonal

i.e. innter product is 0.

This implies dot product of x and y is 0

Then x.y =0

i.e. x^2+y^2 +2x.y = x^2+y^2-2x.y\\||x+y||=||x-y||

Proved

Converse part:

Let ||x+y||=||x-y||

Square also would be equal

||x+y||^2=||x-y||^2\\||x||^2+||y||^2+2x,t=||x||^2+||y||^2-2x.y\\x.y =0

Hence inner product of x and y is 0
