Let x = a + bi and y = c + di and z = f + gi. Which statements are true? check all of the boxes that apply. X + y = y + x (x × y
Mars2501 [29]

The true statements after evaluating the expression based on principle of commutativity and associativity are :

A: x + y = y + x

B; (x × y) × z = x × (y × z)

D: (x + y) + z = x + (y + z)

We are given;

x = a + bi

y = c + di

z = f + gi

Now according to properties of algebra, we know that;

  • Commutative property states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. For example; a + b = b + a

  • The Associative property states that; a × ( b × c) = b × (a × c) = c × (b × a)

Looking at the options :

A) x + y = y + x ; This is true as it follows Commutative property of addition

B) (x × y) × z = x × (y × z) ; This is true as it follows the Associative property.

C) x - y = y - x ; this is false as it does not follow both properties.

D) (x + y) + z = x + (y + z) ; This is true as it follows the Commutative property.

E) (x – y) – z = x – (y – z) ; This is False as it does not follow any of the 2 properties.

Florence is 45 years old, and she makes $65,000 per year. if florence were to die, how much would the beneficiaries of her life
ki77a [65]

Answer: she would receive 39,000 and that is 60% of her incomeExplanation: Now as you can she is making 65,000 per year. So you multiply 65,000 with 60/100. You make 60% into 60/100 because it's a percent and a decimal. Like I was saying if you multiply 65,000 with 60/100 you will get 39,000 which is 60% of her tax income

if my answer is incorrect or if i made a mistake pls let me know, please and thank you :)
