The required values of slope and y-intercept are 10 and 15.

The formula for these lines is y = mx + b, where m denotes the slope and b the y-intercept. Our line has a slope of 3 and a y-intercept of -5, which we know from the question. By entering these numbers, we obtain the equation of our line as y = 3x - 5.

We have,

y = 10x + 15

On comparing with general equation of line.

Y = mx + c

m is slope of line, c is y-intercept.

Then,

m = 10

And

y-intercept = 15

Thus,the required values of slope and y-intercept are 10 and 15.

The degree of financial leverage for Foggy Futures Weather Forecasters

is 1.06

Degree of Financial leverage (DFL) = (EBIT) / (EBT)

Earnings Before Interest and Taxes (EBIT) = $750,000

Amount to be given as loan on $1000000

$1,000,000 x 4.5% = $1,000,000 x 4.5/100

= $45000

To find EBT ( Earnings Before Tax),

EBT = EBIT - 45000

       = 750000 - 45000

EBT = 705000

∴ DFL =  (EBIT) / (EBT)

          = 750000/705000

 DFL = 1.06

The DFL is a percentage that accountants and financial professionals use to show changes in a company's net income due to changes in its profits before interest and taxes (EBIT).

Earnings before interest and taxes (EBIT) is a measurement of a company's profit in accounting and finance that takes into account all revenues and costs (both operating and non-operating), with the exception of interest costs and income tax costs.ve

the scale factor will be √5.

What is dilation?

resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ. A dilatation ought to either extend or contract the original form. The scale factor is a phrase used to describe this transition.

The scale factor is defined as the difference in size between the new and old images. An established location in the plane is the center of dilatation. The dilation transformation is determined by the scale factor and the center of dilation.

The domain of the function f(x) = x² is all real numbers, including negative numbers, zero, and positive numbers.

The domain of a function is the set of all values for which the function is defined. For the function f(x) = x², the domain is all real numbers. This includes negative numbers, zero, and positive numbers. This means that the function is defined for any real number, no matter how large or small. In other words, the domain of f(x) = x² is the set of all real numbers, {x ∈ R}. This is because the square of any real number is still a real number, and so the function is defined for all real numbers. Thus, the domain of f(x) = x² is all real numbers.

Logarithmic functions are important largely because of their relationship to exponential functions.

What is logarithm ?

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.

The first section explains the meaning of the logarithmic function f (x) = c·loga(x - h) + k. It describes how to evaluate logarithms and how to graph logarithmic functions. This section also addresses the domain and range of a logarithmic function, which are inverses of those of its corresponding exponential function.

The next section presents two special logarithmic functions--the common logarithmic function and the natural logarithmic function. The common logarithm is log10x, and it corresponds to the "log" button on most calculators. The natural logarithm is logex, and it corresponds to the "ln" button on most calculators. The natural log has a particular use in economics--it is used to perform calculations involving compound interest.

A possible second point with a y-coordinate of 8 is equal to 5.

In Mathematics, the slope of a straight line can be calculated by using this this mathematical expression;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

From the information provided above, we have the following slope and data points on the line:

Points on x-axis = (1, 2).

Points on y-axis = (_, 8).

Slope, m = 3/2

Substituting the given points into the slope formula, we have the following;

Slope, m = (y₂ - y₁)/(x₂ - x₁)

3/2 = (8 - 2)/(x₂ - 1)

3/2 = 6/(x₂ - 1)

Cross-multiplying, we have:

3(x₂ - 1) = 12

x₂ - 1 = 12/3

x₂ - 1 = 4

x₂ = 4 + 1

x₂ = 5

In conclusion, we can logically deduce that the second point (x₂) is 5.

Step-by-step explanation:

Transformation of the parent function it represents, linear translation down 3 units.

By modifying the value of x (for example, y(x) = x + 2) or by multiplying x by a constant (for example, y(x) = 3x), you can examine the graphs of linear functions. Do not forget that y(x) = x is the linear parent function. Its most fundamental and straightforward form is this.

The graph of y = f (x - h) is translated h units to the RIGHT of the graph of the parent function if h > 0, and it is translated h units to the LEFT if h 0.

as in f(x) = ( x – 3)

The graph of y=f(x-h) is a translation of |h| units to the LEFT of the graph of the parent function if h 0; otherwise, it is a straight line.

The equation y = 3x - 1 and x² + y² = 73 then x = -1, y = -2.

Simultaneous linear equations are a pair of linear equations in two or three variables that are solved simultaneously to arrive at a single answer.

Simultaneous equations are two or more algebraic equations that share the same unknown variables and have the same solution for each of them. The simultaneous equations must therefore have a single solution, according to this.

Add together the equations if the signs vary. Subtract the indications from one another if they match. Different Add, Same Subtract, or DASS, is a simple way to remember this.

Substitute y = 3x + 1 in [tex]$x^2+y^2=5$[/tex]

[tex]$$x^2+(3 x+1)^2=5 \quad \Rightarrow \quad 10 x^2+6 x-4=0$$[/tex]

Hence

[tex]$$\begin{aligned}& 5 x^2+3 x-2=0 \Rightarrow 5 x^2+5 x-2 x-2=0 \quad \\\& 5 x(x+1)-2(x+1)=0 \quad \Rightarrow \quad(5 x-2)(x+1)=0\end{aligned}$$[/tex]

Hence, either [tex]$x=\frac{2}{5}, y=3 \times \frac{2}{5}+1=\frac{11}{5}$[/tex]

When k = -1/2, the equation has real and equal roots of x = 2.

An equation is a mathematical statement that two expressions are equal. It consists of two expressions, one on each side of an equal sign. Equations are used to solve problems in mathematics, chemistry, physics, engineering, and other sciences. They can also be used to define relationships between different variables or constants. Equations are an important tool for understanding the world around us.
The value of k in the given equation is -1/2. This is because when k is equal to -1/2, the equation has real and equal roots of x = 2. This can be verified by substituting k = -1/2 and x = 2 into the given equation:

KX² + 5x + 4 = 0
(-1/2) (2²) + 5(2) + 4 = 0

The set of polynomials is not closed under division.

A polynomial is a mathematical statement made up of exponents, constants, and variables that are mixed using addition, subtraction, multiplication, and division operations. Polynomial means "many terms" since it combines the words poly-, which means "many," and -nomial, which in this context means "term." A polynomial may have exponents (like the 2 in y2), constants (like x and y), variables (like the x and y exponents), and other terms, but only those that can be mixed using addition, subtraction, multiplication, and division are permitted. Constants, variables, and exponents are all permitted in polynomials, but variable division is never permitted.

In addition, they are now only limited to a finite number of terms, which can be one or more.
