The function f(x) = StartRoot negative x EndRoot is represented by the graph. Which statement is correct?

Svetlanka [38]

Answer:

D. The range of the function is all real numbers greater than or equal to 0.

Step-by-step explanation:

The graph of the function $y=\sqrt{-x}$ is shown in attached diagram.

1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is

$x\in (-\infty,0]$

2. The range of the function is the set of all possible values for output (for y), so the range of this function is

$y\in [0,\infty)$

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.

L'età media di Aldo, Bruno, Carlo e Davide è 16 anni. Se non si tiene conto di Davide, l'età media dei tre rimanenti sale a 18.

photoshop1234 [79]

Answer:

Davide's age is 10.

L'età di Davide è 10.

Step-by-step explanation:

The average age of Aldo, Bruno, Carlo and Davide is 16 years.

I am going to say that:

x is Aldo's age.

y is Bruno's age.

z is Carlo's age.

w is Davide's age.

Average of the 4 is 16 years.

This means that:

$16 = \frac{x + y + z + w}{4}$

$x + y + z + w = 64$

If we do not consider Davide, the mean is 18. So

$18 = \frac{x + y + z}{3}$

$x + y + z = 54$

Replacing in the first equation:

$x + y + z + w = 64$

$54 + w = 64$

$w = 10$

Davide's age is 10.

L'età di Davide è 10.

Three times the sum of a number n plus 1 equals two times the sum of the number plus 4. Which equation can be used to find n?

KengaRu [80]

Answer:

B.

Step-by-step explanation:

3(n+1)=2(n+4)

3 × n + 3 × 1 = 2 × n + 2 × 4

3n + 3 = 2n + 8

3n - 2n = 8 - 3 we regroup by categories (unknown and number)

n = 5
