Line m passes through the points (6, 10) and (1, 6) & line n passes through the points (2, -1) and (8, 5) , both the lines are neither parallel nor perpendicular.

As given in the question,

Given two lines 'm' and 'n'

Line m passes through the points

(x₁ ,y₁) =(6,10)

(x₂ ,y₂)=(1,6)

Slope of the line m 'm₁'

= (y₂ -y₁)/ (x₂ -x₁)

= (6 -10) / (1 - 6)

=-4 / -5

=4 / 5

Line n passes through the points 'm₂'

(x₁ ,y₁) =(2,-1)

(x₂ ,y₂)=(8 ,5)

Slope of the line m

= (y₂ -y₁)/ (x₂ -x₁)

= (5 - (-1)) / (8 - 2)

= 6 / 6

= 1

m₁ ≠ m₂

m₁ × m₂ ≠-1

Therefore, line m passes through the points (6, 10) and (1, 6) & line n passes through the points (2, -1) and (8, 5) , both the lines are neither parallel nor perpendicular.

The expressions related to the roots of each quadratic equation are listed below:

Case 1 - x² + 3 · x - 9 = 0

Roots: α = - 3 / 2 - 3√5 / 2, β = - 3 / 2 + 3√5 / 2

a) α + β = - 3

b) α² + β² = 27

c) α³ + β³ = - 108

Case 2 - x² + 4 · x - 2 = 0

Roots: α = - 2 - √6, β = - 2 + √6

a) α + β = - 4

b) α² + β² = 20

c) α³ + β³ = - 88

This question consists in two parts, find the roots by factoring the quadratic equations by algebra properties and determine the expressions based on the two roots of each expression. A root is a value of x such that the polynomial is equal to zero.

Case 1

x² + 3 · x - 9 = 0

x² + 3 · x = 9

x² + 3 · x + 9 / 4 = 9 + 9 / 4

(x + 3 / 2)² = 45 / 4

x + 3 / 2 = ± 3√5 / 2

x = - 3 / 2 ± 3√5 / 2

The roots are α = - 3 / 2 - 3√5 / 2 and β = - 3 / 2 + 3√5 / 2 and the following expressions are evaluated:

a) α + β = - 3

b) α² + β² = (- 3 / 2 - 3√5 / 2)² + (- 3 / 2 + 3√5 / 2)² = 27

c) α³ + β³ = (- 3 / 2 - 3√5 / 2)³ + (- 3 / 2 + 3√5 / 2)³ = - 108

Case 2

x² + 4 · x - 2 = 0

x² + 4 · x + 4 = 6

(x + 2)² = 6

x + 2 = ± √6

x = - 2 ± √6

The roots are α = - 2 - √6 and β = - 2 + √6 and the following expressions are evaluated:

a) α + β = - 4

b) α² + β² = (- 2 - √6)² + (- 2 + √6)² = 20

c) α³ + β³ = (- 2 - √6)³ + (- 2 + √6)³ = - 88

The complete statement would be 'Because it is given that ∠2 is supplementary to ∠3, lines a and b are parallel by Same-Side Interior Angles Postulate'

In this question, we have been given some information about lines a, b, k and m.

We need use this information and determine which lines in the figure are parallel.

We have been given angle 2 is supplementary to angle 3.

We know that, the sum of the angles on the same side of the transversal which are inside the two parallel lines is always 180°

Also, supplementary angles are the angles whose sum is 180°

i.e., ∠2 + ∠3 = 180°

From above we conclude that, the lines and b are parallel and line k would be the transversal.

Therefore, the complete statement would be 'Because it is given that ∠2 is supplementary to ∠3, lines a and b are parallel by Same-Side Interior Angles Postulate'

56 small cubes can be placed in the given cuboid that has the given dimensions.

A cuboid's volume can be calculated using the formula below:

Volume of a cuboid = (length)(width)(height).

A cube has equal height, length, and width. Therefore, the volume of a cube is calculated as:

Volume of a cube = (side length)³.

The number of small cubes that can be placed in the given cuboid = volume of the cuboid/volume of one small cube.

Find the volume of the cuboid:

Length = 60 cm

Height = 54 cm

Width = 30 cm

Volume of the cuboid = (60)(54)(30)

Volume of the cuboid = 97,200 cm³

Find the volume of one cube:

Side length of one small cube = 12 cm

Volume of one small cube = (12)³

Volume of one small cube = 1,728 cm³.

Number of small cubes that will be placed in the cuboid = 97,200/1,728 ≈ 56 cubes.

Answer:

(a - b)/(a + b).

Step-by-step explanation:

a²-ab-ac+bc / a² +ab-ac-bc

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

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

The (a - c) is common to top and bottom, so

= (a - b)/(a + b).

The result of the Nested absolute inequality  when resolved gives:
x = -10, 0. See the solution below.

It is to be noted that when one absolute-value expression is inside another one, this is called a "nested" expression. Absolute expressions are expressions that values that can NEVER be negative.

The solution hence is given as follows:

Given: ||x-5|4|≤1

One absolute-value expression is stacked inside another in this equation. I'll work from the outside in, sorting items into their respective cases. Assume the argument of the outer bars is negative (do the "minus" case):

Step 1 - first splitting:

|x-5| -4 ≤ -1
|x-5|  ≤ 3

I have to stop here since the last statement above states that an absolute value equals a negative number. Absolute values, on the other hand, are never negative! As a result, this step is invalid; it yields no viable solutions to the original problem.

Now I'll look at the scenario where the argument of the outside bars is positive (the "plus" case):

|x-5| -4 ≤ 1

|x-5|  ≤ 1 + 4

Recall that absolute values are never negative. This equation is correct, and I've isolated the leftover absolute value, so I'll go over the two situations again.

Step 2 - First, consider the "minus" case:

x+5  ≤ -5

x ≤ -5-5
x≤ -10

The variable can have a "minus" value; the sole constraint is that an absolute-value expression cannot have a "minus" value. Now consider the "plus" case:

⇒ x + 5 ≤ 5 again recall that this is an absolute expression hence the laws of polarity while cross the inequality sign is suspended.

x ≤ 5-5

x≤0

Hence the answer which is complete is:

x = -10, 0

The equation is

2.54-x+12 = 21-42.5x+7

Rearrange the terms are do the suitable arithmetic operation in the equation

2.54-x+12= 21-42.5x+7

-x+12+2.54 = -42.5x+7+21

Add the like terms together

-x+14.54 = -42.5x+28

Here we have to rearrange the term and make the all the like terms in each sides

Move 14.54 to the right hand side and move -42.5x to the left hand side

Then the equation will become

-x+42.5x = 28-14.54

41.5x = 13.46

x = 13.46/41.5

In my opinion, Report 1 is more persuasive than Report 2 due to the fact that the margin of error in Report 1 is narrower than in Report 2.

This is further explained below.

Generally,  we consider report one and report two

For Report

at 98% confidence interval = $64.35 to $83.59

Therefore, the Margin of error

M.E= $83.59 - $64.35

M.E = $19.24

For Report 2:

95% confidence interval = $58.37 to $71.93

Margin of error

M.E= $71.93 - $58.37

M.E= $13.56

Since Report 1 has a smaller margin of error than Report 2, I find Report 1 to be more convincing.

In conclusion, A report with a lower margin of error, in my opinion, is often more credible than one with a bigger one.

This is because more exact data indicates a report with a reduced margin of error.

To put it another way, information in a report with a lower margin of error is more likely to be correct than information in a report with a higher margin of error.

Thus cost per person c as a function of the number of people n is

c(n) = 43 + (n-1)(43-(n-1)2) and amount she makes is  $229

In the problem it is given that Elizabeth gives a walking tour of a popular tourist city to one person for 43 to increase her​ business, she would lower the price by​ $2 per person for each additional person. we have to find the cost per person c as a function of the number of people n on the tour. Also the amount she makes for a tour with 7 people.

So we can write it as

c(1) = 43

c(2) = 43 + 41

c(3) = 43 + 2(43-2*2)

c(4) = 43 + 3(43-3*2)

c(n) = 43 + (n-1)(43-(n-1)2)

To find the amount she makes we write c as a function of n where n=7

c(7) = 43 + 6(43-6^2) = 43 + 6*31 = 43 + 186 = $229

Thus cost per person c as a function of the number of people n is c(n) = 43 + (n-1)(43-(n-1)2) and amount she makes is  $229.

The given equations (5b - 2)² + 4 = 25b²– 20b and (2x² + y²)(2x² - y²) = 4x² – y have been found not to be true identities

A) We want to check if (5b - 2)² + 4 = 25b²– 20b is a true identity.

A true identity is an equality that holds true regardless of the values chosen for its variables. They are used in simplifying or rearranging algebra expressions. By definition, the two sides of an identity are interchangeable, so we can replace one with the other at any time.

(5b - 2)² + 4 when expanded gives;

25b² - 20b + 4 + 4 = 25b² - 20b + 8

That is not equal to the right hand side and as such, we can say that both equations are not true identities
