What property justifies line 2 to line 3? 4 – 3x2 + 2x – x2 + 3 + x2 Line 1 4 + 3– x2 + x2 – 3x2 + 2x Line 2 7– x2 + x2 – 3x2 +
podryga [215]

Given:

The steps of simplification of the expression.

4-3x^2+2x-x^2+3+x^2

To find:

The properties to justify the line 2 and line 3.

Solution:

We have,

4-3x^2+2x-x^2+3+x^2

Line 1: 4+3-x^2+x^2-3x^2+2x        (Rearranging the terms)

Line 2: 7-x^2+x^2-3x^2+2x        (Combining the constant terms)

Line 3: 7+0-3x^2+2x        (Additive inverse property)

Line 4: 7-3x^2+2x        (Additive identity property)

Therefore, the justifications of Line 2 and Line 3 are combining the constant terms and additive inverse property respectively.

The March utility bills (in dollars) of 30 homeowners are listed below. 44 38 41 50 36 36 43 42 49 48 35 40 37 41 43 50 45 45 39
Ulleksa [173]

Step-by-step explanation:

What we will do is create a table with the data they give us, the first thing will be to organize it from smallest to largest, like this:

33, 35, 35, 36, 36, 36, 37, 38, 38, 39, 40, 40, 41, 41, 41, 42, 42, 43, 43, 43, 44, 45, 45, 47, 48, 48, 49, 50, 50, 50

Now we know that the smallest number is 33 and the largest is 50, to create 5 ranges, we will calculate the difference and divide by 5.

(50 - 33) / 5 = 3.4

Therefore we will make ranges of 3 and 4, values, like this

Rank 1: 33 - 36

Rank 2: 37 - 39

Rank 3: 40 - 43

Rank 4: 44 - 46

Rank 5: 47 - 50

We will calculate the frequency distribution of values in each range:

Rank 1: 6

Rank 2: 4

Rank 3: 10

Rank 4: 3

Rank 5: 7

A cone is twice as tall as a cylinder of the same radius. what is the ratio of there volumes?
Murrr4er [49]
Cylinder) = Bh, where B is the area of each of the two circular bases and h is the height of the cylinder. ... Therefore, for a cone which has the same radius and height as a cylinder, we see that the volume of the cone is one-third (1/3) the volume of the cylinder
