6X + 8Y - 4Z = 5
1X + 2Y + 5Z = 9
9X - 3Y + 3Z = 6
Por favor cómo se resuelve esta matriz por método Gauss-Jordan
Responder:
la solución (x, y, z) es (4.48, 4.86, -1.04)
Explicación paso a paso:
Dadas las ecuaciones simultáneas;
6X + 8Y - 4Z = 5 .... 1
1X + 2Y + 5Z = 9 ... 2
9X - 3Y + 3Z = 6 .... 3
Primero necesitamos reducir el sistema de ecuaciones
Ecuación 1 * 1
Ecuación 2 * 4
__________
6X + 8Y - 4Z = 5
4X + 8Y + 20Z = 36
Restar
6x-4x - 4z-20z = 5-36
2x-24z = 31 ... 4
también
ecuación 2 * 3
ecuación 3 * 2
_______________
1X + 2Y + 5Z = 9 * 3
9X - 3Y + 3Z = 6 * 2
_______________
3x + 6y + 15z = 27
18x - 6 años + 6z = 12
Agregar
3x + 18x + 15z + 6z = 27 + 12
21x + 21z = 39 ...... 5
Resolviendo 4 y 5
2x-24z = 31 ... 4 * 21
21x + 21z = 39 ...... 5 * 2
____________
42x - 504z = 651
42x + 42z = 78
Sustraer
-504x - 42z = 651-78
-546z = 573
z = -573/546
z = -1.05
Sustituye z = -1.05 en 4
De 4;
2x-21z = 31
2x - 21 (-1,05) = 31
2x + 22,04 = 31
2x = 31-22.04
2x = 8,96
x = 8,96 / 2
x = 4,48
Obtener y
De 2:
X + 2Y + 5Z = 9
4.48 + 2y + 5 (-1.04) = 9
2 años + 4,48-5,2 = 9
2y = 9 + 0,72
2 años = 9,72
y = 9,72 / 2
y = 4,86
Por tanto, la solución (x, y, z) es (4.48, 4.86, -1.04)

Find the equation of a line with the given information:
f(- 6) = 8 and f( - 8) = – 1.
Wrote answer in point slope form
Answer:
[tex]y -8= \frac{9}{2}(x +6)[/tex]
Step-by-step explanation:
Given
[tex]f(-6) = 8[/tex]
[tex]f(-8) = -2[/tex]
Required
Determine the equation in point-slope form
The general function notation is:
[tex]f(x) = y[/tex]
So, in [tex]f(-6) = 8[/tex]
[tex](x_1,y_1) = (-6,8)[/tex]
[tex]f(-8) = -1[/tex]
[tex](x_2,y_2) = (-8,-1)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]
[tex]m = \frac{-1-8}{-8-(-6)}[/tex]
[tex]m = \frac{-1-8}{-8+6}[/tex]
[tex]m = \frac{-9}{-2}[/tex]
[tex]m = \frac{9}{2}[/tex]
The equation is then calculated as:
[tex]y -y_1= m(x-x_1)[/tex]
[tex]y -8= \frac{9}{2}(x - (-6))[/tex]
[tex]y -8= \frac{9}{2}(x +6)[/tex]
The Johnson family is taking a road trip. They travled 456 miles in 8 hours. James said their rate is 57 miles per hour.
Do you agree with James? Explain
Answer:57
Step-by-step explanation:
I would do 456/8 to figure out how many miles they went every hour, 456/8 is 57 so James is correct.
What is the initial value of the function f(x)=9(2/3)x+4?
Answer:
x=-2/3
Step-by-step explanation:
f(x)=9×2/3x+4
0=9×2/3x+4(substitute f (x) =0)
0=9×2/3x+4
0=3×2x+4
0=6x+4
-6x=4( move the variable to left side and change the sign)
Divide both sides.. x=-2/3
The initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]
We have a function f(x) = [tex]9(\frac{2}{3} )x +4[/tex]
We have to find the initial value of the function f(x).
How will you calculate the initial value of a function f(x) ?We can calculate the initial value of a function f(x) by equating the function f(x) = 0, and find the value of [tex]x[/tex].
In the question given - f(x) = [tex]9(\frac{2}{3} )x +4[/tex]. In order to calculate the initial value of this function - equate f(x) = 0. Therefore -
[tex]9(\frac{2}{3} )x +4 =0\\[/tex]
6x + 4 = 0
x = [tex]\frac{-4}{6}[/tex]
x = [tex]\frac{-2}{3}[/tex]
Hence, the initial value of the function f(x) = [tex]\frac{-2}{3}[/tex]
