Using a property of operations, what can you say about the sums of (-13.2) 8.1 and 13.2 (-8.1)

1 answer:

7 0

No matter where the negative sign is, the product will always be negative, so is the number itself.

13.2(-8.1)=-106.92

twice of that would be -213.84.

first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).

Graph the function defined by f(x) = (x+21)

Inga [223]

Answer:

Step-by-step explanation:

Consider the parent function $y=|x|.$ The graph of this function is represented as red graph in attached diagram.

Now consider the function $y=|x+2|.$

Remind main translations of the graph of the function $y=f(x):$

$y=f(x-a)$ - translation a units to the right;
$y=f(x+a)$ - translation a units to the left;
$y=f(x)+a$ - translation a units up;
$y=f(x)-a$ - translation a units down.

In your case, the graph of the function $y=|x+2|$ is translated graph of the function $y=|x|$ 2 units to the left (blue graph). So, correct answer is option A.

Find 3x2 − y3 − y3 − z if x = 3, y = −2, and z = −5.

IceJOKER [234]

3x²-y³ - y³ - z if x = 3, y = -2, z = -5

Simply plug in all the values :)

3(3²) - (-2³) - (-2³) - (-5)

Simplify.

3(9) + 2³ + 2³ + 5

Simplify.

27 + 8 + 8 + 5

Simplify.

35 + 13

Simplify.
