Commutative property of addition is

a+b = b+a, that is if we change the positions of the numbers, the result is same. For e.g. 2 + 3 = 3+2 .

In the given question , which is (-1+i) + (21+5i), we can use commutative property of addition to simplify it to the simpler form .

And the first step is to combine the like terms that is

(-1+21)+(i+5i). And tht's the required answer or that's the first step which is the commutative property of addition .

Anni [7]

Answer:

6 clown fish and 4 angel fish

Step-by-step explanation:

<u>lets say he bought 8 clown fish. </u>

12*8 = 96

the last 4 dollars wont be used.

<u>lets say he bought 7 clown fish-</u>

12*7 = 84

100 - 84 = 16. 16 is not a multiple of 7.

<u>lets say he bought 6 clown fish,</u>

12*6 = 72

100 - 72 = 28

28/7 = 4

If David has $100 dollars to spend and wants to spend every dollar, he can buy 6 clown fish and 4 angel fish.

Use the graph of a translated function below to answer this question
Talja [164]

The graph of the function y=x^3 has the point of inflection at the origin. From the diagram you can the that the graph y=f(x - h) + k has the point of inflection at point (-2,-3). So you should translate the graph of the function y=x^3 2 units to the left and 3 units down. This translation is acting on function  y=f(x) in the following way:

  • translation 2 units to the left - y=f(x+2);
  • translation 3 units down - y=f(x+2)-3.

Then h=-2 and k=-3.

Answer: correct choice is A.
