Answer:

x = 7 , y = 4

Step-by-step explanation:

the triangle on the right has 3 congruent angles and is therefore equilateral with 3 congruent sides, so

3x - 5 = 5y - 4 → (1)

the triangle on the left has 2 congruent angles and is therefore isosceles with the 2 legs being congruent, so

3x - 5 = y + 12 → (2)

we have 2 equations with 3x - 5 on the left side so equate the right sides

5y - 4 = y + 12 ( subtract y from both sides )

4y - 4 = 12 ( add 4 to both sides )

4y = 16 ( divide both sides by 4 )

y = 4

Then

5y - 4 = 5(4) - 4 = 20 - 4 = 16 , so

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

An arithmetic progression (AP) is a sequence of numbers such that the difference between any two consecutive terms is always the same.

This common difference is called the common ratio of the arithmetic progression. The general form of an arithmetic progression is a, a + d, a + 2d, ..., where a is the first term and d is a common difference.

The nth term of an arithmetic progression can be found by using the formula: a_n = a + (n-1)d, where a is the first term, d is a common difference, and n is the position of the term in the progression.

If a, b, and c are in arithmetic progression, then the common difference is (b-a) = (c-b).

If d, e, and f are also in arithmetic progression, then the common difference is (e-d) = (f-e).

If a, d are the same and b, e are the same, then c = f.

so the common difference between both progressions is the same, and c = f

let , and be arithmetic progressions. if and , then what is ? let , and be arithmetic progressions. if and , then what is the common difference

Answer:

First find what f(-4) is, it is 2. Then substitute the 2 into x for e(x). Then is becomes e(2) which equals -4. The output is the same as the input because they are inverses. When putting the output of the original equation as the input of the inversed equation, the output of the inversed equation becomes the input of the original equation.

The function e(f(-4)) = -4. This happens because when two function machines are pushed together, the output of the first machine is used as the input for the second machine.

The inverse of a function f(x) is a function e(x) such that e(f(x)) = x for all x in the domain of f(x). To find the inverse of Amanda's favorite function, f(x) = 1 + sqrt(x + 5), we need to isolate x in the expression 1 + sqrt(x + 5) and call it y:

y = 1 + sqrt(x + 5)

Squaring both sides of the equation, we get:

y^2 = 1 + 2sqrt(x + 5) + (x + 5)

y^2 - 1 = 2sqrt(x + 5) + x + 5

Expanding the square on the left side, we get:

y^2 - y - 6 = x

So the inverse function, e(x), can be defined as:

e(x) = y^2 - y - 6

Finally, to evaluate e(f(-4)), we first need to find f(-4), then use the result as an input to the inverse function e(x):

f(-4) = 1 + sqrt(-4 + 5) = 1 + sqrt(1) = 1 + 1 = 2

e(f(-4)) = e(2) = 2^2 - 2 - 6 = 4 - 8 = -4

Therefore, e(f(-4)) = -4.

This happens because when two function machines are pushed together, the output of the first machine is used as the input for the second machine.

The inverse of Amanda's favourite function takes the output of the first machine and finds the original input that would have produced the same output. In this case, the original input was -4.

It's important to note that even if the sample is random, there's still a chance that the sample may not be representative of the population, this is known as sampling error.

The fundamental act of thinking about anything logically and sensibly is best described as reasoning.

It depends on how the teacher choose the class members. Because every student had an equal chance of being chosen, the sample, if the students were chosen at random, is likely to be indicative of the class' performance on the quiz. However, the sample would not be indicative of the class's performance on the quiz if the teacher arbitrarily chose the students, for instance, by selecting only the best or the worst performers.

In general, if a sample is large enough and random, it is thought to be representative of the population. The likelihood that the sample is representative of the population rises with greater sample sizes. Since only 8 students were chosen in this instance, it's possible that the results don't accurately reflect how the entire class did on the quiz.

The term "sampling error" refers to the possibility that a sample, even one drawn at random, may not be representative of the population as a whole.

What is the 45-45-90 triangle?

A 45-45-90 triangle is a special type of right triangle where the angles measure 45 degrees, 45 degrees, and 90 degrees. The sides of the triangle are in a specific ratio to each other. The hypotenuse, or the longest side of the triangle, is the same length as the other two sides (the legs). This side length is also equal to the square root of 2 times the length of either leg. The legs of the triangle are congruent to each other. This triangle is also known as an "isosceles right triangle".

In the given figure, we can apply a 45-45-90 triangle,

side opposite to 45 = 1/√2 * Hypotenuse

At the height of 2500 m, the temperature will be T = 16 ℃.

Given is that air temperature of a mountain drops by 2 ℃ for every 500 m of elevation. If the air temperature is 26 ℃ at the base of the mountain, at what elevation will the air temperature be 16 ℃.

2 ℃ for every 500 m of elevation.

Then, for 1 m of elevation, it will change by (2/500) or (1/250) ℃

We can write the function as -

T{x} = 26 - {x/250}

Now, for T = 16 ℃, we can write -

26 - {x/250} = 16

26 - 16 = x/250

10 = x/250

x = 2500 m

Here we have given in the question that if you draw a line that is 1/2 an inch on paper its proportional to 10 feet long on the house.

The percentage decrease from the August price to the September price = 20%

Here, In July the price of a holiday is £500.

And in August the price increases by 25%.

Let 'p' represents the price of a holiday.

First we need to find the value of the 25 percent of £500.

25% of £500

= 500 × (25/100)

= £125

so, the value of p would be,

p = £500 + 25% of £500

p = £500 + £125

p = £625

In September the price drops to £500 again.

i.e., p = 500

So, the decrease in price is: 625 - 500 = 125

The equation of the inverse of y = x + 3 is y = x - 3.

The theory used in this question is the concept of inverse relationships. In mathematics, an inverse relationship is a relationship where two variables are related in such a way that when one variable increases, the other decreases.

In this case, the relationship between x and y is represented by the equation y = x + 3.

To find the inverse of this equation, we need to switch the coordinates in each ordered pair, which is done by subtracting 3 from the output (y) for each ordered pair.

This gives us the equation y = x - 3, which is the inverse of y = x + 3.
