Hello! To find the answer to this, let’s do 6x + 4x = 180. Combine like terms and you get that 10x = 180. Divide each side by 10 in order to get 18. Angle 1 = 108 degrees and Angle 12 = 72 degrees. Odd number angles match each other and even number angles match each other. In this case, 5 has the same angle measurement as 1, which is 108. The answer is D: 108 degrees.

Which of the following are the features for the graph of the parent absolute value function? Select all that apply.

Burka [1]

absolute value graph looks like a V, with the vertex at the origin.

1. the domain (x-values) is: (∞, ∞) TRUE

2. the range (y-values) starts at the vertex: [0, ∞) FALSE

3. the function decreases when left of vertex and increases when right of vertex: decreases (-∞, 0) TRUE

4. f(x) = |x| = +/-x

f(-x) = |-x| = +/-x

f(x) = f(-x) so the function is even TRUE

5. every x-value has a corresponding y-value (there are no gaps) so the function is continuous. TRUE

Answers: 1, 3, 4, 5

You are Looking at two area rugs for your bedroom. One is a square with a side length of 6.3 feet the other is rectangle that is

Ray Of Light [21]

Answer:

Part a) The square rug cover the greater area

Part b) The square rug cover 0.33 square feet more than the rectangular rug

Step-by-step explanation:

step 1

Find the area of the square rug

The area of a square is

$A=b^2$

where

b is the length of the square

we have

$b=6.3\ ft$

substitute

$A=(6.3)^2=39.69\ ft^2$

step 2

Find the area of the rectangular rug

The area of the rectangle is

$A=LW$

we have

$L=4.8\ ft\\W=8.2\ ft$

substitute

$A=4.8(8.2)=39.36\ ft^2$

step 3

Compare the areas

$39.69 > 39.36$

The square rug cover the greater area

step 4

Find the difference

$39.69-39.36=0.33\ ft^2$

The square rug cover 0.33 square feet more than the rectangular rug

Name the property the equation illustrates.<br> (ab)3 = a (63)<br> Accociative Property of addition

Delvig [45]

<h3><u>Question:</u></h3>

Name the property the equation illustrates

(ab)3 = a(b3)

A. Commutative property of addition

B. Associative property of Multiplication

C. Associative Property of Addition

D. Inverse Property of Multiplication

<h3><u>Answer:</u></h3>

Associative property of Multiplication

<h3><u>Solution:</u></h3>

From given equation

(ab)3 = a(b3)

We have to find the property used here

We find the brackets are interchanged

So here, given is a multiplication equation

Therefore, Associative property of Multiplication is used

<h3><u>Associative property of Multiplication:</u></h3>

This property says that when we are multiplying it does not matter where you put the parenthesis

The result will be same wherever we put the parenthesis in multiplying two or more numbers

Which means,

$a \times (b \times c) = (a \times b) \times c$

Therefore, from given,

$a \times (b \times 3) = (a \times b) \times 3$

Thus associative property of multiplication is used
