Answer:
[tex]x_{1} = \frac{176}{127} + \frac{71}{127}x_{4}\\\\ x_{2} = \frac{284}{127} + \frac{131}{254}x_{4}\\\\x_{3} = \frac{845}{127} + \frac{663}{254}x_{4}\\[/tex]
Step-by-step explanation:
As the given Augmented matrix is
[tex]\left[\begin{array}{ccccc}9&-2&0&-4&:8\\0&7&-1&-1&:9\\8&12&-6&5&:-2\end{array}\right][/tex]
Step 1 :
[tex]r_{1}[/tex]↔[tex]r_{1} - r_{2}[/tex]
[tex]\left[\begin{array}{ccccc}1&-14&6&-9&:10\\0&7&-1&-1&:9\\8&12&-6&5&:-2\end{array}\right][/tex]
Step 2 :
[tex]r_{3}[/tex]↔[tex]r_{3} - 8r_{1}[/tex]
[tex]\left[\begin{array}{ccccc}1&-14&6&-9&:10\\0&7&-1&-1&:9\\0&124&-54&77&:-82\end{array}\right][/tex]
Step 3 :
[tex]r_{2}[/tex]↔[tex]\frac{r_{2}}{7}[/tex]
[tex]\left[\begin{array}{ccccc}1&-14&6&-9&:10\\0&1&-\frac{1}{7} &-\frac{1}{7} &:\frac{9}{7} \\0&124&-54&77&:-82\end{array}\right][/tex]
Step 4 :
[tex]r_{1}[/tex]↔[tex]r_{1} + 14r_{2}[/tex] , [tex]r_{3}[/tex]↔[tex]r_{3} - 124r_{2}[/tex]
[tex]\left[\begin{array}{ccccc}1&0&4&-11&:-8\\0&1&-\frac{1}{7} &-\frac{1}{7} &:\frac{9}{7} \\0&0&- \frac{254}{7} &\frac{663}{7} &:-\frac{1690}{7} \end{array}\right][/tex]
Step 5 :
[tex]r_{3}[/tex]↔[tex]\frac{r_{3}. 7}{254}[/tex]
[tex]\left[\begin{array}{ccccc}1&0&4&-11&:-8\\0&1&-\frac{1}{7} &-\frac{1}{7} &:\frac{9}{7} \\0&0&1&-\frac{663}{254} &:-\frac{1690}{254} \end{array}\right][/tex]
Step 6 :
[tex]r_{1}[/tex]↔[tex]r_{1} - 4r_{3}[/tex] , [tex]r_{2}[/tex]↔[tex]r_{2} + \frac{1}{7} r_{3}[/tex]
[tex]\left[\begin{array}{ccccc}1&0&0&-\frac{71}{127} &:\frac{176}{127} \\0&1&0&-\frac{131}{254} &:\frac{284}{127} \\0&0&1&-\frac{663}{254} &:\frac{845}{127} \end{array}\right][/tex]
∴ we get
[tex]x_{1} = \frac{176}{127} + \frac{71}{127}x_{4}\\\\ x_{2} = \frac{284}{127} + \frac{131}{254}x_{4}\\\\x_{3} = \frac{845}{127} + \frac{663}{254}x_{4}\\[/tex]

What are the coordinates of the midpoint of AB where A(-7, 2) and B(5, - 9)? 0 (-2.5, -1) 0 (-6, - 5.5) (1, -9) (-1, - 3.5)
Answers
Answer:
(-1, -3.5)
Step-by-step explanation:
The coordinates of the midpoint of segment AB can be obtained via the midpoint formula:
Xmp = (Xa + Xb)/2
which in our case is: (-7 + 5)/2 = -2/2 = -1
Ymp = (Ya + Yb) / 2
in our case: (2 - 9) / 2 = -7/ 2= -3.5
Therefore select the point: (-1, -3.5) from your given list of options.
what is the range and domain of the function {(2,5),(8,3),(1,5),(7,9)}
Answers
Answer:
In general for a point we have (in, out)
The domain is the set of all the 'in's and the range is the set of all the 'out's
Domain: {2, 8, 1, 7} or {1, 2, 7, 8} in order
Range: {5, 3, 9} or {3, 5, 9}
Sets do not contain duplicates so 5 appears only once.

Rachel has a 4-liter jug of water. She uses it to fiI| 3 small vases each with 900 mL of water. How much water does Rachel use to fill the vases? How much water is left in the jug? Show your work. (1 liter = 1,000 milliliters)
Answers
Answer:
Step-by-step explanation:
4 * 1000 = 4000. 4000/900 = 4.4. 4.4 - 3 = 1.4. 900*1.4 = 1260. 1260 mil of water is left. Rachel used 2700 mil to fill the vases.
After solving the expression, the amount of water left in the jug will be equal to 1.3 liters.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.
Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
The total amount of water = 4 liters
1 liter = 1000 milliliters then,
4 liters = 4000 milliliters.
3 small vases of 900 ml used the water.
Then, total water used = 3 × 900 = 2700 mL
Amount of water left = 4000 - 2700 = 1300 mL.
Then, water left in the jug will be,
x = (1300 × 4)/4000
x = 1.3 L
