Russell has been offered positions by two cable companies. The first company pays a salary of $17,000 plus a commission of $20 for each cable package sold. The second pays a salary of $14,300 plus a commission of $30 for each cable package sold. How many cable packages would need to be sold to make the total pay the same?
Answers
Russell has to sell 270 cable packages to make the total pay of both the companies as same.
Suppose that Russell sells x cable packages such that the total pay of both the companies is the same.
Then the revenue Russell would make at the first company is $17000+20x
And, the revenue Russell would make at the second company is
$14300+30x
Since, the above two values are equal
so, 17000+20x=14300+30x
⇒17000-14300=30x-20x
⇒10x=2700
⇒x=270
The above problems are called mathematical modelling.
Mathematical modelling is the process of locating such equations to explain actual occurrences.
These formulae are referred to as mathematical models together with the definitions given to the variables.
Therefore, Russell has to sell 270 cable packages to make the total pay of both the companies as same.

Given functions f ( x ) = 1 √ x and m ( x ) = x 2 − 4 , state the domains of the following functions using interval notation.
Domain of f ( x ) /m ( x ):
Domain of f ( m ( x ) ):

Answers
The domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x) = 1/√x
m(x) = x² - 4
Domain of f(x)/m(x):
f(x)/m(x) = (1/√x)/(x² - 4)
f(x)/m(x) = 1/√x(x² - 4)
The denominator cannot be zero:
√x(x² - 4) ≠ 0
x(x - 2)(x+2) ≠ 0
x ≠ 0, 2, -2
and x > 0
Domain of f(x)/m(x) is: (0, ∞) - {0, 2, -2} or [tex]\:\left(0,\:2\right)\cup \left(2,\:\infty \:\right)[/tex]
Domain of f(m(x)):
f(m(x)) = 1/√(x² - 4)
x² - 4 > 0
Domain: [tex]\rm \left(-\infty \:,\:-2\right)\cup \left(2,\:\infty \:\right)[/tex]
Domain of m(f(x)):
= ((1/√x)² - 4)
Domain: [tex]\:\left(0,\:\infty \:\right)[/tex]
Thus, the domain of a function f(x)/m(x) = 1/√x(x² - 4) is (0, ∞) - {0, 2, -2} for other function is shown in the solution.

THAT IS CORRECT TRUST ME
Step-by-Step Explanation:
We know, in a Parallelogram the angles on the same side of the Transversal are Supplementary (add up to 180°).
∠A and ∠B add up to 180°
∠A = 68°
∠B = Unknown
Therefore,
∠A + ∠B = 180°
68° + ∠B = 180°
∠B = 180° - 68°
=> ∠B = 112°
How does supply and demand affect consumers?
Answers
Supply and demand can help consumers make informed decisions about their purchases, anticipate price fluctuations, and stay up to date with market trends.
We have to give that,
To find supply and demand affect on consumers.
Supply and demand have a significant impact on consumers.
When the demand for a product or service is high and the supply is limited, it can lead to higher prices.
On the other hand, when there is high supply and low demand, prices tend to be lower.
For consumers, this means that when the demand for a product is high, they may have to pay more or face limited availability.
Conversely, when the demand is low, consumers may find discounted prices or special promotions.
Supply and demand dynamics also influence the choices available to consumers.
For example, if the demand for a particular type of product increases, companies may introduce new variations or brands to meet consumer preferences.
This can lead to a broader range of options for consumers to choose from.
In summary, understanding supply and demand can help consumers make informed decisions about their purchases, anticipate price fluctuations, and stay up to date with market trends.

Solve -6 < 2x + 4 ≤ 16
Answers
Answer:
Step-by-step explanation:
Solve -6 < 2x + 4 ≤ 16
To solve for x, we need to simplify the statement.
let's get rid of the 4 that is added to 2x.
do that by subtracting 4 on all sides (3 sides).
-6 - 4 < 2x + 4 - 4 ≤ 16-4
We get: -10 < 2x ≤ 12
Now, let's get rid of the 2 that gets multiplied to x.
do that by dividing all sides by 2.
-10 : 2 < 2x : 2 ≤ 12 : 2
We get: -5 < x ≤ 6
X = {-4,-3,-2,-1,0,1,2,3,4,5,6}

How to Find the Equation of a Line in Point-Slope Form and Slope-intercept Form?Where (a, b) is a point on the line and m is the slope of the line, the equation in point-slope form for such line would be: y - b = m(x - a).Where b = y-intercept and m = slope, the slope-intercept form for the equation of the line is expressed as: y = mx + b.Slope (m) = rise/run = -(2/2) = -1
