It looks like you might have intended to say the roots are 7 + i and 5 - i, judging by the extra space between 7 and i.
The simplest polynomial with these characteristics would be
but seeing as each of the options appears to be a quartic polynomial, I suspect f(x) is also supposed to have only real coefficients. In that case, we need to pair up any complex root with its conjugate to "complete" f(x). We end up with
which appears to most closely resemble the third option. Upon expanding, we see f(x) does indeed have real coefficients:
Una linea recta ( cualquier eje coordenado es una línea recta) queda definida si se conocen dos puntos que están sobre ella.
Solución:
Ecuación del eje x y = 0
Ecuación del eje y x = 0
Para darle respuesta a la pregunta podemos seguir el siguiente procedimiento:
- Escogemos dos puntos arbitrarios sobre el eje x, por ejemplo
P ( 2 ; 0 ) y Q ( 5 ; 0 ) ( todos los puntos sobre el eje x tienen coordenada y = 0.
Según la cual m = (y₂ - y₁)/ ( x₂ - x₁ ) m = 0
- Usamos la ecuación pendiente-Intercepto
y = m×x + b donde m es la pendiente y b el intercepto con el eje y
y entonces tenemos:
- m = 0 b ( 0 ; 0 )
- Por sustitución en la ecuación pendiente-intercepto
y = 0
Procediendo de forma similar obtendremos la ecuación del eje y
P´( 0 ; 4 ) Q´( 0 : 8 ) entonces
y = m×x + b
En este caso, la pendiente no es definida ( tang 90° ) y b es de nuevo el punto b ( 0 ; 0).
A partir de que todos y cada uno de los puntos sobre el eje y son de valor 0 para x, concluímos que ecuación del eje y es
x = 0

Answer:
I need the passage, so that i can help
Step-by-step explanation:
I think the correct answer from the choices listed above is the last option. The axiom that allows x(10) to be written 10x would be the commutative property of multiplication. It states that numbers can be added or multiplied in any order. Hope this answers the question. Have a nice day.
Answer:
The numbers are 42 and 49
Step-by-step explanation:
Let's make it into a simple equation. Make the ratios into a single variable like this: 6x+7x=91. If you simplify it more you would get 13x=91. From here divide both sides by 13. This will result with x being 7. But the problem wants you to find 6x and 7x. If you multiply 7 with 6 you would have an answer of 42. If you multiply 7 with 7 you get 49. If you want to check add 42 and 49. If you get 91, this means that the answer is correct
