Step-by-step explanation:

f(x) = 3x + 2

g(x) = 4x

= f(x) + g(x)

= 3x + 2 + 4x

= (3 + 4)x + 2

= 7x + 2

(f+g)(x) = 7x + 2

en el año 5 antes de Cristo, un chico cumplió 13 años.¿en qué año nació?, ¿en qué año nació su madre si lo tuvo con 22 años?
ki77a [65]

Answer:

El chico nació en el año 18 antes de cristo.

La madre nació en el año 40.

Step-by-step explanation:

Las respuestas son fáciles:

- Si en el año 5, el hijo tiene 13 años, hagamos que a partir del año 0 después de cristo sea positivo.

-13-(-5) = -18

- Madre:

-18-22 = -40

Entonces, su edad debería ser negativa, simplemente cambiamos el símbolo y lo pasamos a positivo.

Solve the system of equations using substitution y=x-1 and y=-2x+5
pav-90 [236]
Since the two equations equal y, set them equal to each other.

x-1=-2x+5

From there, solve for x.

First get x on one side, by using the addition property of equality.

x-1=-2x+5
3x-1=5

Isolate x by adding 1.
3x=6

Lastly get x all by itself by dividing each side by 3.
x=2

You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)

y=x-1
y=2-1
y=1

OR

y=-2x+5
y=-2(2)+5
y=-4+5
y=1

Final answer:
x=2 and y=1
