What is the proof of the non-existence of a solution of a Diophantine equation?

The midpoint of the points A (1, 5) and B (-7, -5) is found to be (-3, 0)

The midpoint of a line segment is the centroid of the segment. It is equally distant from both of the ends and hence cuts the section in half.

The formula to determine the center point of a straight line using the coordinates of its endpoints is known as the midpoint formula in coordinate geometry.

The formula is of the form

X= (x₂ + x₁)/2

Y = (y₂ + y₁)/2

Given points A (1, 5) and B (-7, -5)

X= (1 - 7)/2 = -3

Y = (5 - 5)/2 = 0

the midpoint is (-3, 0)

Answer:

33.33%

Step-by-step explanation:

You start with 36 eggs, and 24 are removed and fried. This means that the remaining eggs are the difference of 36 and 24:

36 - 24 = 12

There are 12 eggs left! To find the percentage of remaining eggs, write a ratio comparing the number of eggs that remain to the original amount of eggs:

[tex]\frac{12}{36}[/tex]

Now, simplify the fraction into a decimal:

12 ÷ 36 = 0.3333...

Multiply a decimal by 100 to convert it to a percentage:

0.3333... ⋅ 100 = 33.33...%

Rounded to the nearest hundredth, the percent of remaining eggs is 33.33%

The final statement is: The system of equations have unique solution.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Answer: To calculate the balance of the savings plan after 9 months with an APR of 3% and monthly payments of $200, we need to take into account the interest earned on the account.

First, we will calculate the interest earned by multiplying the principal (initial amount) by the interest rate (APR) and the number of months.

Interest = Principal * Interest Rate * Number of months

Interest = 200 * 0.03 * 9 = 54

Then, we will add the interest earned to the total amount of payments made.

Total = Principal + Interest + Payments

Total = 200 + 54 + (200 * 9) = 200 + 54 + 1800 = 2054

So the savings plan balance after 9 months with an APR of 3% and monthly payments of $200 is $2054.

Answer:

Input = 5

Step-by-step explanation:

Output = Answer a.k.a. f(x)

Input = x

We start by replacing f(x) with the output, which is 11

11 = 4x-9. I like making it opposite. It's easier in my eyes.

Making it opposite it's 4x-9 = 11

Now we need to get x by itself. The opposite of -9 is +9. So if we add 9 to each side, it deletes the 9 from the left and puts it on the other side, making it;

4x = 11 + 9. 11 + 9 is 20, so....

4x = 20.

Now 4x is the same as 4 times x. The opposite of times is divide. So let's divide by 4 on both sides. That gets rid of the 4 on the left side and puts it on the other side, making it;

x = 20/4. 20/4 is 5, so...

x = 5

Step-by-step explanation:

f(x) = 4x - 9

4x - 9 = 11

4x = 11 + 9

4x = 20

x = 20 ÷ 4

x = 5

f(h(x)) = -2x^2 + 12x + (-12) in terms of x.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.

To find f(h(x)), we first need to substitute h(x) into f(x).

f(h(x)) = f(4(x-3)²)

Now we can substitute 4(x-3)^2 into f(x)

f(h(x)) = 6 - 1/2(4(x-3)^2)

= 6 - 2(x-3)^2

= 6 - 2(x^2 - 6x + 9)

= 6 - 2x^2 + 12x - 18

Hence, f(h(x)) = -2x^2 + 12x + (-12) in terms of x.

C. Determine if the system containing u, v, and b is consistent. If the system is consistent, then b is in Span{u,v} is correct.

To show that a vector b is in Span{u,v}, one way is to determine if it can be written as a linear combination of the vectors in the set, i.e., if there exist scalars h and k such that b = hu + kv. If this is the case, the system containing the equations hu + kv = b is consistent, meaning that there exist values of h and k that make the equation true. Therefore, if the system is consistent, it can be concluded that the vector b is in Span{u,v}.

Answer:

To graph the equation y = 1/2x - 4, we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

In this equation, the slope is 1/2, and the y-intercept is -4. The slope represents the steepness of the line, and the y-intercept is the point at which the line crosses the y-axis.

To graph the equation:

Plot the y-intercept, which is (-0, -4)

Using the slope, we can pick a second point on the line. The slope of 1/2 tells us that for every 2 units in the x direction, we will move 1 unit in the y direction. So we can pick a point that is 2 units to the right of the y-intercept, such as (2,0).

Connect the two points to get a straight line

The resulting graph will be a straight line that passes through the point (-0, -4) and (2, 0) and continues in both directions.

Alternatively, you can use a table of values to plot the points that belongs to the line and connect them, for example:

x | y

-2 | -5

-1 | -4.5

0 | -4

1 | -3.5

2 | -3

These are few points on the graph and with more points you can connect them and see the shape of the graph.

Answer:

k = -12.6

Step-by-step explanation:

Given rational polynomial:

[tex]\dfrac{x^3-2x^2+kx-12}{x-5}[/tex]

When we divide a polynomial f(x) by (x − d) the remainder is f(d).

If the remainder is zero, then (x - d) must be a factor of f(x).

If a cubic polynomial is divided by (x - d) then:

[tex]\implies (x-d)(ax^2+bx+c)[/tex]

where:

If the constant of the cubic polynomial is -12 and d = 5:

[tex]\implies -cd=-12[/tex]

[tex]\implies -5c=-12[/tex]

[tex]\implies c=2.4[/tex]

The leading coefficient of the cubic polynomial is one.  Therefore:

[tex]\implies (x-5)(x^2+bx+2.4)[/tex]

Expand and collect like terms:

[tex]\implies x^3+bx^2+2.4x-5x^2-5bx-12[/tex]

[tex]\implies x^3+(b-5)x^2+(2.4-5b)x-12[/tex]

The find the value of b, compare the coefficients of the term in x²:

[tex]\implies b-5=-2[/tex]

[tex]\implies b=3[/tex]

To find k, substitute the found value of b into the coefficient of x:

[tex]\implies k=2.4-5b[/tex]

[tex]\implies k=2.4-5(3)[/tex]

[tex]\implies k=-12.6[/tex]

Answer:

–12.6

Step-by-step explanation:

[tex] \frac{ \\ {x }^{3} - {2x}^{2} + kx - 12}{x - 5} = 0[/tex]

that means (x–5) is a factor of x³ – 2x² +kx – 12

since it resulted to zero according to the rules of zeros of polynomial.

x–5 = 0

x = 5

by substituting

f(x) = 5³ – 2(5)² + k(5) – 12 = 0

125 – 50 + 5k – 12 = 0

75 + 5k – 12 = 0

5k + 75 – 12 = 0

5k + 63 = 0

5k = –63

Francis purchases a package of 450 plastic forks but only uses 315 of them, therefore he uses 70% of the available supply.

In math, a % is a number or ratio that is expressed as a fraction of 100. There are also sporadic uses of the abbreviations "pct.," "pct," and "pc." However, the percent sign "%" is frequently used to indicate it. The percentages' total quantity has no dimensions. Percentages are fundamentally fractions when the denominator is 100. Put a percent sign (%) next to a number to indicate that it is a percentage. For instance, if you successfully answer 75 out of 100 questions on a test (75/100), you get a 75%. Divide the money by the total to get percentages, then multiply the resulting number by 100. The formula (value/total) x 100% is used to calculate the percentage.

Answer:

P = 5x + 33 = 58

Q = R = 3x+46 = 61

Step-by-step explanation:

angles in a triangle add up to 180 degrees

the angles in an isosceles triangle that correspond to the two congruent sides (are opposite the sides) are also congruent

that means that angle R = angle Q because QP and RP are congruent

angles = 5x+33, 3x+46, 3x+46

5x+33 + 3x+ 46 + 3x+46 = 180

11x + 125 = 180

subtract 125 from both sides to isolate the x and its coefficient

11x = 55

divide both sides by 11 to find x

x = 5

P = 5x + 33 = 58

Q = R = 3x+46 = 61
