Answer:
No solution 0≠3
Step-by-step explanation:
simplify parenthesis:
4x+4x+3=8x+6
combine like terms:
8x+3=8x+6
subtract three from both sides
8x=8x+3
subtract 8x from both sides
0≠3
This equation has no solution
i hope this helps u, pls give brainliest i only need one more then i level up and a thx, leave a comment if i am wrong
Answer:
x > 3
Step-by-step explanation:
-17x + 2 < -10x - 19
_____________
.Subtract 2 from both sides.
-17x + 2 - 2 < -10x - 19 - 2
____________________
.Simplify.
-17x < -10x - 21
__________________
.Add 10x to both sides.
-17x + 10x < -10x - 21 + 10x
____________________
.Simplify.
-7x < -21
_________________
.Multiply both sides by -1 (reverse the inequality).
(-7x)(-1) > (-21)(-1)
______________________
.Simplify.
7x > 21
_______________________
.Divide both sides by 7.
7x/7 > 21/7
_____________________
.Simplify.
x > 3
Answer with Step-by-step explanation:
We are given that two matrices A and B are square matrices of the same size.
We have to prove that
Tr(C(A+B)=C(Tr(A)+Tr(B))
Where C is constant
We know that tr A=Sum of diagonal elements of A
Therefore,
Tr(A)=Sum of diagonal elements of A
Tr(B)=Sum of diagonal elements of B
C(Tr(A))= Sum of diagonal elements of A
C(Tr(B))= Sum of diagonal elements of B
Tr(C(A+B)=Sum of diagonal elements of (C(A+B))
Suppose ,A=
B=
Tr(A)=1+1=2
Tr(B)=1+1=2
C(Tr(A)+Tr(B))=C(2+2)=4C
A+B=
A+B=
C(A+B)=
Tr(C(A+B))=2C+2C=4C
Hence, Tr(C(A+B)=C(Tr(A)+Tr(B))
Hence, proved.
