The value not in the solution is x = -10.2
How to determine the value not in the solution?The inequality expression is given as:
-4x - 6.8<34
Add 6.8 to both sides of the inequality
So, we have:
-4x < 40.8
Divide both sides by -4
x > -10.2
This means that only values greater than -10.2 are in the solution set
Hence, the value not in the solution is x = -10.2

Elena and Diego each wrote equations to represent these diagrams. For each diagram decide which equation you agree with, and solve it. You can assume that angles that look like right angles are indeed right angles.
Elena: X=35
Diego: X+35=180
Answer: Diego is correct, and X = 145
Step-by-step explanation:
The line that 35* and x* rest on must equal 180*. Elena cannot be right if we assume this, as 35 + 35 = 70. We must then move onto Diego's formula.
[tex]X + 35 = 180[/tex]
[tex]180 - 35 = X[/tex]
[tex]X = 145[/tex]
Solving this, we would subtract 35 from 180, leaving us with 145*. This must be correct as the solution would give us the total we need.
What is the rate of change of the area of a circle with respect to the radius when the radius is 4 in?
The rate of change of the area of circle with respect to radius is: 8π.
What is the rate of change of a function?The rate at which one quantity changes in relation to another quantity is known as the rate of change of a function.
Now,
Area of a circle having radius (=r) is given by: A = πr²
The rate of change of area of the circle will then be given by:
[tex]\frac{dA}{dr}=\pi \frac{d}{dr}(r^{2})=2\pi(r)[/tex]
For r = 4, [tex]\frac{dA}{dr}=2\pi(4)=8\pi[/tex]
Hence, the rate of change of area of the circle when the radius is 8π.

32 g≈ ___ oz
32g = 1.12877oz or 32 grams is equivalent to 1.12877 ounces.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.
The sentence states an equality between units of weight: grams and ounces.
From there, we can say that we are asked how many ounces are there in 32 grams.
Converting grams to ounces, we must use the conversion
1 gram = 0.035274 ounces
32 grams = 32 (0.035274 ounces)

What irrational number is associated with a point on a number line?
In this problem we find the location of a point on a number line, which is related to an inexact irrational number, that is, an irrational number that is not equivalent to any rational number. The point is between two exact irrational numbers, that is, √16 = 4 and √25 = 5.
There are two options: (i) √17, (ii) √24. √24 is close to 5, but √17 is close to 4. Thus, the number shown on the number line could be related to the inexact irrational number √17.

The given situation is an example of an Observational Study.
What is an Observational Study?In observational studies, the impact of a risk factor, diagnostic test, treatment, or other intervention is observed without an attempt to alter who is or is not exposed to it. There are two categories of observational studies: cohort studies and case control studies.
Cohort study: Any group of people who are connected in some way constitutes a cohort for research purposes. For instance, a birth cohort is made up of all individuals born within a specific period of time. Researchers contrast the outcomes for cohort members who have been exposed to a specific variable with those for cohort members who have not.
Case control study: In this method, researchers choose individuals who already have a health issue (referred to as "cases") and a control group that is similar but free of the issue.

If point A (-5, 9) is reflected across the x-axis, what will be the new coordinates of the image, A'?
please help! I am in the middle of a test! I am offering 30 points.
The new coordinates of the image A' will be (-5, -9).
Here, we are given a point on the cartesian plane- A (-5, 9)
It is reflected along the x axis to form a new point A'
Originally, we can see that the point A will be in the 2nd quadrant as x is negative and y is positive.
Now, when it is reflected across the x axis, the point will shift from the 2nd quadrant to the 3rd quadrant.
In the third quadrant, both x and y values are negative. Thus the coordinates of the reflected point A' will become (-5, -9).
Note that the absolute values of the point will not change when it is reflected. It is only the signs that change.

If f (x) = 2 x + 5 and three-halves are inverse functions of each other and StartFraction 41 Over 8 EndFraction,
The value of the inverse function f⁻¹(8) is [tex]\frac{3}{2}[/tex] .
An inverse function in mathematics is a function that "undoes" another function.
In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹ .To calculate the inverse of the function f (x) = 2 x + 5 we simply write the function in the form y = 2x + 5 .
Now we solve the equation for x.
∴ y = 2x + 5
or, 2x = y-5
or, x = (y-5)/2
Hence the inverse of the function is given as:
f⁻¹ (x) = (x - 5 ) / 2
Now we have to find the value of f⁻¹ (8).
f⁻¹ (8) = (8-5) / 2
or, f⁻¹ (8) = 3 / 2
Hence the value of f⁻¹ (8) is 3 / 2 .

A truck can be rented from company a for $110 a day plus $0.70 per mile, company b charges $80 a day plus $0.80 per mile to rent the same truck. find the number of miles in a day at which the rental costs for company a and company b are the same.
The number of miles for same rental costs are 300 miles.
Let the number of miles be x.
Firstly calculating the cost of Company a -
Total cost = One day cost + Number of miles × Cost per mile
Total cost = 110 + 0.70x
Calculating the cost of Company b -
Total cost = One day cost + Number of miles × Cost per mile
Total cost = 80 + 0.80x
Now, for the same rental cost, we will equate the two expressions. This will calculate the value of x.
110 + 0.70x = 80 + 0.80x
Rearranging the expression -
110 - 80 = 0.80x - 0.70x
Performing subtraction
30 = 0.10x
Shifting the values on other side of equation
x = 30/0.10
Performing division
x = 300
Hence, the rental cost for both companies will be same for 300 miles.
