The original fraction described in the question is; 25/31
How to simplify fractions?Let the numerator be x and let the denominator be y.
We are told that the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2,the result is 4. Thus;
4x/(y - 2) = 4
4x = 4y - 8
4x - 4y = -8 -----(1)
The numerator of the fraction is increased by 15 and 2 subtracted from the double of the denominator, the result is 5/4. Thus;
(x + 15)/(2y - 2) = 5/4
4x + 60 = 10y - 10
4x - 10y = - 70 ----(2)
Subtract eq 2 from eq 1 to get;
6y = 62
y = 31/3
Thus;
4x - 4(31/3) = -8
Multiply through by 3 to get;
12x - 124 = -24
12x = 100
x = 25/3
Thus, the fraction is;
(25/3)/(31/3) = 25/31

y = -6x + 5
-2x + y = 5
Answer: 0,5
x = 0
y = 5
Answer: (0,5)
Step-by-step explanation:
Since "y" is equal to -6x+5 everywhere you see a "y" you can replace it with -6x+5.
-2x-6x+5=5
Combine like terms
-8x+5=5
Isolate x (subtract 5 from both sides)
-8x=0
Solve for x
x=0
Now that you have the value for "x" you can substitute the value into either equation and solve for y
-2(0)+y =5
y=5
or
y=-6(0)+5
y=5

What is derivative?A derivative is a two-party contract whose price or value is based on an underlying asset. Futures, options, forward contracts, and swaps are the four most popular types of derivatives. It is a financial instrument whose price and value are determined by the underlying assets.
According to question:The derivative of the natural logarithmic function is given by:
d/dx [ln(u(x))] = 1/u(x) * du/dx
So, to find the derivative of f(x) = ln(1 - x), we need to find the derivative of the inside function, which is 1 - x:
f'(x) = 1/[1 - x] * d/dx [1 - x]
= 1/[1 - x] * (-1)
= -1 / (1 - x)
So the derivative of f(x) = ln(1 - x) is f'(x) = -1 / (1 - x).

the product of permutation matrices is again a permutation matrix. True/False
The statement which is given as , "The product of permutation matrices is again a permutation matrix." is True.
A permutation matrix is a square matrix whose entries are either 0 or 1 and has exactly one "1" in each row and each column. In other words, it is a matrix that represents a permutation of the rows (or columns) of the identity matrix.
When two permutation matrices are multiplied, the result is another square matrix with exactly one "1" in each row and each column. To see why this is true, consider two permutation matrices, A and B. Suppose that A is a m x m matrix and B is a m x m matrix. The product of these two matrices is another m x m matrix, C = AB.
Each entry in the matrix C is given by the dot product of the corresponding row in A and the corresponding column in B. If the row in A has a "1" in the i-th position and the column in B has a "1" in the j-th position, then the i,j-th entry in C will be "1".
Since both A and B are permutation matrices, each row in A and each column in B has exactly one "1". This means that each row in C will have exactly one "1", and each column in C will also have exactly one "1". Hence, C is also a permutation matrix.

what is 2 tbsp to g ?
Since, 1 Tablespoon is equal to 15 Gram.
Therefore, 2 Tablespoon is equal to 1/8 cups or 29.5 grams.
Gram:
The gram (originally gram; SI unit symbol g) is a unit of mass in the International System of Units (SI), equal to one thousandth of a kilogram.
Originally defined in 1795 as "the absolute weight of a volume of pure water equal to one hundredth of a meter at the temperature at which ice melts." The positive temperature (~0 °C) was later changed to 4 °C, the temperature of maximum density of water.
However, towards the end of the 19th century, attempts were made to make the kilogram the base unit and the gram the derived unit. In 1960, the new International System of Units defined the gram as one thousandth of a kilogram (i.e., 1 gram equals 1 × 10-3 kg. As of 2019, the kilogram is defined by the International Bureau of Weights and Measures based on the fixed value of Planck's constant (h),
6.62607015 × 10-34 kg⋅m2⋅s-1.
According to the Question:
Convert from tablespoons to grams by multiplying the volume by 14.786765 times the density of the ingredient or material.
Using this simple formula, it can be converted to:
Grams = Tablespoons × 14.786765 × Ingredient Density
Therefore,
Grams = 02 × 14.786765
= 29.57353
So the volume in grams is equal to the number of tablespoons times the density of the material or material times 14.786765.

The answers to all parts are shown below.
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
The polynomial zeros are given as:
x = 7, x = -1 and x = -3
x - 7 = 0, x + 1 = 0 and x + 3 = 0
So, f(x) = (x - 7)(x + 1)(x + 3)
f(x) = (x - 7)(x² + 4x +3)
f(x) = x³ -3x² -25 x -21
Now, Rational function g(x)
g(x) = f(x) / (x² - x + 2)
After Factorizing
g(x) = (x-2) - 25x+ 25 / (x² - x + 2)
The slant asymptote is the quotient i.e. x - 2
Hence, the slant asymptote of the function g(x) is x - 2
So, the discontinuities of g(x)
g(x) = (x³ -3x² -25 x -21) / (x² - x + 2)
Set the denominator to 0
x² - x + 2 = 0
(x - 2)(x + 1) = 0
x= 2 or x= -1.
So, the discontinuities and their types are:
Essential discontinuity at x = 2
Removable discontinuity at x = -1

Anna to Benito 2° angle of elevation
Anna to Deon 3° angle of elevation
Charlie to Benito 5° angle of depression A trapezoid ABCD named Anna, Benito, Charlie and deon on the four coordinates respectively with angle ABC as 124 degree, BCD as 85 degree and CDA as 96 degree
The area of the enclosure is approximately 128.6 acres
To find the area of the trapezoid ABCD, we first need to find the lengths of its parallel sides. Let's use the fact that the angles of a quadrilateral add up to 360 degrees:
Angle ABC = 124 degrees
Angle BCD = 85 degrees
Angle CDA = 96 degrees
Angle DAB = 360 - 124 - 85 - 96 = 55 degrees
Now we can use the tangent function to find the lengths of the sides:
tan(2 degrees) = (height of AB) / (distance between Anna and Benito)
(height of AB) = (distance between Anna and Benito) × tan(2 degrees)
(distance between Anna and Benito) = (713 - 690) / tan(2 degrees) ≈ 18490.3 ft
(height of AB) ≈ 429.4 ft
Similarly, we can find the height of CD:
tan(3 degrees) = (height of AD) / (distance between Anna and Deon)
(height of AD) = (distance between Anna and Deon) × tan(3 degrees)
(distance between Anna and Deon) = (725 - 690) / tan(3 degrees) ≈ 8639.5 ft
(height of AD) ≈ 459.6 ft
Now we can use the trapezoid area formula:
Area = (height of AB + height of CD) × (sum of the parallel sides) / 2
Area = (429.4 + 459.6) × ((18490.3 + 8639.5) / 2) / 5280 ≈ 128.6 acres

How to Find the Value of Square Root of 9?
The value of the square root of 9 is 3.
The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, we want to find the square root of 9.
We can start by finding the perfect squares that are less than 9. The perfect squares less than 9 are 1 and 4. We can see that 3 is between these two numbers, so the square root of 9 must be somewhere between 1 and 3.
We can test whether 3 is the square root of 9 by squaring it: 3 x 3 = 9. This confirms that 3 is indeed the square root of 9.
Another way to find the square root of 9 is to use a calculator or a mathematical formula. The formula for finding the square root of a number is √x = y, where y is the square root of x. In this case, x is 9, so we have √9 = 3.

If Keshawn is 1.45 meters tall. At 12 noon, he measures the length of a tree's shadow to be 15.05 meters. the height of the tree to the nearest hundredth of a meter is 2.02 meters.
How to find the height?To find the height of the tree, we can use the similar triangles method. Let's call the height of the tree "h".
Since Keshawn and the tree are standing in the same spot, the same light source is casting their shadows, so the ratios of their shadow lengths to their heights are equal. This means we can set up the following proportion:
1.45 / h = 15.05 / 10.8
We can solve for "h" by cross-multiplying:
h = 15.05 * 1.45 / 10.8
h = 2.02 meters
Therefore, the height of the tree to the nearest hundredth of a meter is approximately 2.02 meters.
