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 table of values indicates a proportional relationship between the number of gallons of gas and the number of miles driven, therefore;

A proportional relationship is one in which one variable, y, can be obtained from another variable, x, by multiplying x by a factor.

Please find attached a table showing the number of gallons of gas and the miles driven obtained from a similar question online

Let x represent the number of gallons of gas and let f(x) represent the number of miles driven

The difference between the consecutive terms of the first three values in the number of gallons and miles driven are each equal to 2 and 62 respectively

4 - 2 = 2 - 0 = 2

124 - 62 = 62 - 0 = 62

Therefore, given that the first difference is constant, the first three points have a linear relation, which gives;

Slope of the line = 62/2 = 31

Intercept = 0

Therefore;

f(x) = 31•x

Checking the fourth point, gives;

x = 10

f(10) = 31 × 10 = 310

The relationship between the miles driven, f(x), and the number of gallons is therefore a proportional relationship, which is presented as follows;

f(x) = 31•x

Therefore, if the number of gallons of gas, x, is known, the number of miles driven, f(x), can be found using the equation;

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 solution of the equation 2.54-x+12= 21-42.5x+7 is x = 0.324

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

x = 0.324

multiply the stuff inside paranthesis for the last 2

So a is the outsider

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.

Hence,

let

perimeter of the square = x inches

perimeter of an equilateral triangle = x + 17

Let

side of the square = y

side of the triangle = 8 + y

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

a) α + β = - 3

b) α² + β² = 27

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
