Answer:
The third graph is correct for the inequality 2x + 3y > -3
Step-by-step explanation:
The slope of the graph is –2/3.
The y-intercept is –1
The area above the dashed be line is shaded.
To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.
For example: (1,1)
2(1) + 3(1) > –3
2 + 3 > –3
5 > –3 True.
(x^2 - 1)(x^6 + x^4 + x^2) =
x^2(x^6 + x^4 + x^2) - 1(x^6 + x^4 + x^2) =
x^8 + x^6 + x^4 - x^6 - x^4 - x^2 =
x^8 - x^2 <==
Answer:
x=1
Step-by-step explanation:
- choose a side to get rid of so since its easier to take 6 away from seven we will do that but remember what you do to one side you have to do to the other
- so take away 6x from the left that leaves 0 your equation should look like this 4=-3+7x remember that we have to to it to the right side too
- so take 6x away from the 7x on the right side and that leaves 1x so it should look like this 4=-3+1x
- then since it's a -3 you will need to add 3 for it ton equal 0 so it will look like this 4=7x
- but dont for get to do the same to the other side so add 3 to the 4 on the left so it will look like this 7=7x
- then divide by 7 to get x by itself so it will look like this 7=x
- but you aren't done yet you still have to divide the left by 7 so it will look like this 1=x
and thats all there is to it hope this helps
Answer:
Una matriz hermitiana, o también llamada matriz hermítica, es una matriz cuadrada con números complejos que tiene la característica de ser igual a su traspuesta conjugada.
A=A^*
Donde A^* es la matriz traspuesta conjugada de A.
Step-by-step explanation
Ejemplo de matriz hermitiana de orden 2×2
₍ 5............. 3+7i₎
₍3-7i .............2
₎
Ejemplo de matriz hermitiana de dimensión 3×3
(3............2-i......-5i)
(2+i............0.....9-5i)
(5i.........9+5i.....6)
