Answer:

first number=14.9,second number=89.4 and third number=8.9

Step-by-step explanation:

let the first number be "a" , second number be "b" and third number be "c"

From the question above we know,

b=6a

c=a-6

And b+c=98  

so we can write,

b+c=98  

(6a)+(a-6)=98  

6a+a=98+6

7a=104

a=104/7

∴a=14.9(correct to 3 sig. fig.)

again

b=6a=6(14.9)= 89.4(correct to 3 sig. fig.)

c=a-6=(14.9)-6=8.9(correct to 3 sig. fig.)

Now if u want to make sure that ur answer is correct just add b+c and see if its 98

b+c=98

89.4+8.9=98.3=98(correct to whole number)

Answer:

83

Step-by-step explanation:

x + y + z = 83

(y + 7) + y + 2y = 83

4y + 7 = 83

4y = 76

y = 19

The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.

A check reveals that 26 + 19 + 38 = 83

f(x)=4 hallar el dominio, codominio, ceros o raices, vertices, asintotas, tabla de valores, graficas, identificar el tipo de fun
nekit [7.7K]

Answer:

Tipo de función: Función Constante o Función Polinómica de Orden Cero

Dominio: Dom \{f(x)\} = \mathbb{R}

Codominio: Ran \{f(x)\} = 4

Asíntota: y = 4

Raíces: No tiene.

Vértices: No tiene.

La tabla de valores y el gráfico se encuentran adjuntos al fondo.

Step-by-step explanation:

Sea f(x) = 4, el cual representa a una Función Constante o Función Polinómica de Orden Cero, cuyos dominio y codominio son Dom \{f(x)\} = \mathbb{R} y Ran \{f(x)\} = 4. No tiene vértices. Esta función tiene una asíntota horizontal coincidente con la función (y = 4) y carece de raíces al ser f(x) \ne 0 para todo x\in \mathbb{R}.

Finalmente, agregamos una tabla de valores y la gráfica asociada a la función:

x         -2         -1         0         1          2

y         4          4         4         4         4

What is 2/5 plus 1/3
leva [86]
First, you need to get the denominators (the bottom number) the same.  The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too.   So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5.  Then, since you did it to the bottom, do it to the top as well.  You would get 5/15.

Then, you need to put them side by side.  You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

<u> 6</u> + <u>5</u>     =   <u>11</u>
