Answer:
x = 5 or x = 1
Step-by-step explanation:
Absolute Value Equation entered :
3|3x-9|=18
Step by step solution :
Step 1: Rearrange this Absolute Value Equation
Absolute value equalitiy entered
3|3x-9| = 18
Step 2: Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 3|3x-9|
For the Negative case we'll use -3(3x-9)
For the Positive case we'll use 3(3x-9)
Step 3: Solve the Negative Case
-3(3x-9) = 18
Multiply
-9x+27 = 18
Rearrange and Add up
-9x = -9
Divide both sides by 9
-x = -1
Multiply both sides by (-1)
x = 1
Which is the solution for the Negative Case
Step 4: Solve the Positive Case
(3x-9) = 18
Multiply
9x-27 = 18
Rearrange and Add up
9x = 45
Divide both sides by 9
x = 5
Which is the solution for the Positive Case
Step 5: Wrap up the solution
x=1
x=5
Solutions on the Number Line
Two solutions were found :
x=5
x=1
The second one would prove they are parallel. This is because it uses angles touching both of the parallel lines and uses correct Angle Properties
Answer:
The inner product holds the commutative property while the outer product does not hold. This indicates that and
Step-by-step explanation:
For any two vectors, U and V, given as,
Here a1,a2,a3,b1,b2 and b3,.....,an,bn are real numbers
The products are given as
From this, it is clear that the inner product or the scalar product of two vectors U, V is commutative i.e
Now for the outer or vector product
From this, it is clear that the outer product or the vector product of two vectors U, V is not commutative i.e
However, it is evident that
Sometimes.
This is because natural numbers are 1, 2, 3, 4, 5...
Rational numbers are all numbers that can be simplified into a fraction.
