Apply to Row 2 : Row 2 + Row 1
2x + 2y + 3z = 0
y + 4z = -3
2x + 3y + 3z = 5
Apply to Row 3: Row 3 - Row 1
2x + 2y + 3z = 0
y + 4z = -3
y = 5
Apply to Row 3: Row 3 - Row 2
2x + 2y + 3z = 0
y + 4z = -3
-4z = 8
Simplify rows
2x + 2y + 3z = 0
y + 4z = -3
z = -2

Apply to Row 2: Row 2 - 4 Row 3
2x + 2y + 3z = 0
y = 5
z = -2
Apply to Row 1: Row 1 - 3 Row 3
2x + 2y = 6
y = 5
z = -2
Apply to Row 1: Row 1 - 2 Row 2
2x = -4
y = 5
z = 2
Simplify the rows

<u>z = -2</u>
Answer:
It's 52
Step-by-step explanation:
50 plus 2 is 52 but it's not one if the answers ?
Answer:
Rewriting the expression 
with a rational exponent as a radical expression we get ![\mathbf{\sqrt[9]{3} }](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Csqrt%5B9%5D%7B3%7D%20%7D)
Step-by-step explanation:
We need to rewrite the expression with a rational exponent as a radical expression.
The expression given is:
First we will simply the expression using exponent rule 
As we know 2 and 18 are both divisible by 2, we can write
Now we know that ![a^\frac{1}{9}=\sqrt[9]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7B9%7D%3D%5Csqrt%5B9%5D%7Ba%7D)
Using this we get
![=\sqrt[9]{3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B9%5D%7B3%7D)
So, rewriting the expression with a rational exponent as a radical expression we get
There is nothing there answer
Answer:
The correct option is d.
Step-by-step explanation:
For a question to be answered by an experiment, some conditions need to be satisfied.
An experiment must follow qualitative analysis. In a sense, an experiment must be able to be quantified. Let's take an example:
Suppose a school wants to screen candidates for an entrance level. The candidates must be of a specified number. The exam is taken. The exam scores are tabulated and distributed according to the statistical distribution. In this way, the quantitative distribution in the candidates pass mark cab be quantified.
In the question, the correct option will be d. The program can be tested quantitatively (and generating data).
