If f(X+4) =3x+4 , then find the value of f(4) <br>please explain it clearly .​
Paul [167]

\\ \sf\longmapsto f(x+4)=3x+4

\\ \sf\longmapsto f(x)=3x+4-4

\\ \sf\longmapsto f(x)=3x

Now

\\ \sf\longmapsto f(4)

\\ \sf\longmapsto 3(4)

\\ \sf\longmapsto 12

DerKrebs [107]

Answer:

$8.75

Step-by-step explanation:

STEP TO TAKE TO DETERMINE THE ANSWER

Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5

1\frac{3}{4} = \frac{7}{4}

\frac{7}{4} × 5 = \frac{35}{4} = 8\frac{3}{4} = $8.75

Un padre cede al mayor de sus hijos la quinta parte de su capital, al segundo la cuarta parte del mismo y al tercero le da el re
spayn [35]

Answer:

El padre tenía un capital de 60,000 euros.

El hijo mayor recibe 12,000 euros.

El hijo segundo recibe 15,000 euros.

El hijo tercero recibe 33,000 euros.

Step-by-step explanation:

Sea x el capital total del padre y a,b,c son las asignaciones a los hijos mayor, segundo y tercero. A continuación, construimos las ecuaciones matemáticas a partir de lo descrito en el enunciado:

Hijo mayor

a = \frac{1}{5}\cdot x (1)

Hijo segundo

b = \frac{1}{4}\cdot x (2)

Hijo tercero

c = \left(1-\frac{1}{5}-\frac{1}{4}\right)\cdot x = 33000 (3)

De (3) tenemos que el capital del padre es:

x = \frac{33000}{1-\frac{1}{5}-\frac{1}{4}  }

x = 60000

El padre tenía un capital de 60,000 euros.

Por (1) y (2) determinamos los capitales del hijo mayor y el hijo segundo:

a = \frac{1}{5}\cdot x

x = 12000

El hijo mayor recibe 12,000 euros.

b = \frac{1}{4}\cdot x

b = 15000

El hijo segundo recibe 15,000 euros.
