Which property of real numbers is shown below? -6(4x + 5) = -24x - 30 associative property of addition commutative property of multiplication distributive property inverse property of addition

Answers

Answer 1
Answer:

The Distributiveproperty of addition over multiplication is shown in the expression -6(4x + 5) = -24x - 30.

Given,

-6(4x + 5) = -24x - 30

We need to find out which property is applied in the given expression.

What are the properties of algebra?

Some of the properties are:

- Commutativeproperty of

Addition - a + b = b + a

Multiplication - a x b = b x a

- Associativeproperty of

Addition - (a + b) + c = a + (b + c)

Multiplication - (a x b) x c = a x (b x c)

-Distributiveproperty of addition over multiplication

a x (b + c) = a x b + a x c

a + b x c = (a x c) + (b x c)

- Inverseproperty

a + -a = 0

Inverse property of a is -a.

We have,

-6 ( 4x + 5 )

= (- 6) x 4x + ( - 6 ) x 5

= -24x - 30

If a = -6, b = 4x and c = 5

We have,

= a x ( b + c )

= a x b + a x c

We see that Distributiveproperty of addition over multiplication is applied here.

Thus the Distributiveproperty of addition over multiplication is shown in the expression -6(4x + 5) = -24x - 30.

Answer 2
Answer:

This would be the distributive property!!

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products

hope this helps!

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?

Answers

The question is asking us to find which function in the vertex form is equivalent to f ( x ) = 4 + x^2 - 2 x. We have to add 1 to make a squared binomial ( and also to subtract 1 ). f ( x ) = ( x^2 - 2 x + 1 ) - 1 + 4 = ( x - 1 )^2 + 3. Then we have the vertex point ( 1, 3 ). Answer: The function in vertex form is: f ( x ) = ( x - 1 ) ^2 + 3.

Answer:

Vertex form of the function will be f(x) = (x - 1)² + 3.

Step-by-step explanation:

Vertex form of a quadratic function is given by f(x) = a(x - h)² + k

where (h, k) is the vertex of the given parabola.

Now we will convert the function in the vertex form.

f(x) = x² - 2x + 1 + 3

     = (x - 1)² + 3

Therefore, the vertex form of the function will be f(x) = (x - 1)² + 3

and the vertex will be (1, 3).

Answers

Adding and subtracting amonomial requires having the same variables. No matter how big or small theircoefficient is, if their variables do not match, they cannot be added or subtracted.The crucial part in adding or subtracting monomials is their sign. If the signsare the same, retain the sign. If the signs are different, subtract and keepthe sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y  
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
