The choice shows 19 + 32 + 11 rewritten correctly using the commutative property and then simplified correctly is option B; 19+11+32= 30+32 = 62.

<h3>What is the commutative property of addition?</h3>

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have:

x + y = y + x

WE have given

19 + 32 + 11

The sum would be 62.

We know that by commutative property of addition,

For two numbers x and y,

x + y = y + x

Thus, if we take 3 numbers as a,b and c, then:

c + a + b = c + b + a

Similarly,

19 + 32 + 11 = 19+11+32

= 30+32

= 62

Therefore, the option B  is the correct answer.

Help Please!! NO LINKS AND NEED EXPLANATION!
ikadub [295]

Answer:

Function 1: None of the Above

Function 2: Quadratic

Function 3: Linear

Step-by-step explanation:

Function 1: It isn't linear because the y-axis doesn't go up or down at a constant rate, it isn't quadratic because it doesn't have a vertex, and it isn't exponential because it doesn't continue going up.

Function 2: It has a vertex-(6,32)

Function 3: The y-axis goes up at a constant rate of 6.

Evaluate the function for the given value.<br> If f(x) = -3x2 – 8, then f(-4)= ?
Ganezh [65]

Answer:

The answer is

<h2>f( - 4) =  - 56</h2>

Step-by-step explanation:

f(x) =  - 3 {x}^{2}  - 8 \\

To find f(-4) , substitute the value of x that's - 4 into f(x). That is for every x in f(x) , replace it with - 4

We have

f( - 4) =  - 3 ({ - 4})^{2}  - 8 \\  =  - 3(16) - 8 \\  =  - 48 - 8 \:  \:  \:  \:  \:

We have the final answer as

f( - 4) =  - 56

Hope this helps you
