Tatiana [17]3 years ago
4 0

Step-by-step explanation:

y = 0.5x + 4

When y = 2, x = -4. (shown in graph)

When y = 6, x = 4. (shown in graph)

Hence the domain would be -4 <= x <= 4.

En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor qu
forsale [732]

Answer:

Falso.

Step-by-step explanation:

Acá tenemos la proposición:

"En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores."

Primero tratemos de demostrar que esto es falso, para ello debemos encontrar un solo ejemplo en el que la proposición sea falsa.

Elijamos al número 1 como el número natural,

Elijamos -10 como el número entero negativo.

El producto es:

1*-10 = -10

Ahora veamos si el producto es menor que cada uno de los factores.

-10 < 1 ?

Si, -10 es menor que 1.

Ahora veamos con el otro factor:

-10 < - 10?

No, un número no puede ser menor que si mismo.

Entonces el producto no siempre es menor que cada uno de los factores.

Entonces la proposición es falsa.

Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel.
astra-53 [7]

Answer:

Kevin=335.8years old

Step-by-step explanation:

K - D = 333

K - 2 = 400( D - 2 )

333 + D - 2 = 400D - 800

D - 400D = - 800 - 331

- 399D = - 1130

D = 2.8

K = 333 + 2.8

K = 335.8

Which is a true statement about an isosceles right triangle?
AnnyKZ [126]

Let l be the length of a leg. Using the pythagorean theorem, the hypotenuse is

h = \sqrt{l^2+l^2}=\sqrt{2l^2}=l\sqrt{2}

So, the hypotenuse is \sqrt{2} times as long as either leg.
