The solution of the given system of equations is (0, -4)

We will use the substitution method.

Given the system of equations:

-3x - y = 4   ............ (1)

4x + 2y = -8   ..........(2)

Add 3x to both sides of (1):

-3x - y +3x = 4 + 3x

-y = 4+3x

Multiply by (-1)

y = -(4+3x)

Substitute y = -(4+3x) into equation (2)

4x + 2y = -8

4x + 2. (-(4+3x)) = -8

4x - 8 - 6x = -8

-2x -8 = -8  (Add 8 to both sides)

-2x -8 + 8 = -8 + 8

-2x = 0

x = 0

Substitute x = 0 into:

y = -(4+3x)

y = -(4+3 . 0) = -4

The solution is (0, -4)

The equation \(x^2 - 4x + y^2 + 8y\) can be rewritten as \((x - 2)^2 + (y + 4)^2 = 20\), and the center of the circle is \((2, -4)\) with a radius of \(2sqrt(5).\)

To complete the square and rewrite the equation, let's focus on the terms involving x and y separately.

For \(x^2 - 4x\), we can complete the square by taking half of the coefficient of x, which is -4, and squaring it: \((-4/2)^2 = 4\). Add this value to both sides of the equation:

\(x^2 - 4x + 4 = 4\)

For y^2 + 8y, we can complete the square by taking half of the coefficient of y, which is 8, and squaring it: (8/2)^2 = 16. Add this value to both sides of the equation:

\(y^2 + 8y + 16 = 16\)

Now, let's rewrite the equation using these completed squares:

\((x^2 - 4x + 4) + (y^2 + 8y + 16) = 4 + 16\)

Simplifying the equation:

\((x - 2)^2 + (y + 4)^2 = 20\)

Now we can identify the center and radius of the circle. The equation is in the form\((x - h)^2 + (y - k)^2 = r^2\), where (h, k) represents the center of the circle, and r represents the radius.

From our equation, we can see that the center of the circle is (2, -4) and the radius is \(sqrt(20)\), which simplifies to \(2sqrt(5)\).

The equation \(\[ x^2 - 4x + y^2 + 8y \]\) can be rewritten as \(\[ (x - 2)^2 + (y + 4)^2 = 20 \]\). The center of the circle is (2, -4), and the radius is \(\[ \sqrt{20} \]\).

To rewrite the given equation using the method of completing the square, we need to rearrange the terms and add a constant value on both sides of the equation. Let's start with the given equation:

\(\[ x^2 - 4x + y^2 + 8y \]\)

To complete the square for the x terms, we take half of the coefficient of x (-4) and square it. Half of -4 is -2, and (-2)² is 4. We add this value inside the parentheses to both sides of the equation:

\(\[ x^2 - 4x + 4 + y^2 + 8y \]\)

For the y terms, we follow the same process. Half of the coefficient of y (8) is 4, and (4)² is 16. We add this value inside the parentheses to both sides of the equation:

\(\[ x^2 - 4x + 4 + y^2 + 8y + 16 \]\)

Now, we can rewrite the equation as:

\(\[ (x^2 - 4x + 4) + (y^2 + 8y + 16) = 4 + 16 \]\)

The first parentheses can be factored as a perfect square: (x - 2)².

Similarly, the second parentheses can be factored as a perfect square: (y + 4)². Simplifying the right side gives us:

\(\[ (x - 2)^2 + (y + 4)^2 = 20 \]\)

Comparing this equation to the standard form of a circle, \(\[ (x - h)^2 + (y - k)^2 = r^2 \]\), we can identify the center and radius of the circle. The center is given by (h, k), so the center of this circle is (2, -4).

The radius, r, is the square root of the number on the right side of the equation, so the radius of this circle is \(\[ \sqrt{20} \]\).

The transformation that ALWAYS carries the figure onto itself is a rotation of 90° clockwise about point P .The correct option is  (Option C).

In the given figure, we have two perpendicular lines s and r intersecting at point P in the interior of a trapezoid. We also have a line "liner" that is parallel to the bases and bisects both legs of the trapezoid. Line s bisects both bases of the trapezoid.

Let's examine the given options:

A. A reflection across liner: This transformation does not always carry the figure onto itself. It would result in a reflection of the trapezoid across liner, which would change the orientation of the trapezoid.

B. A reflection across lines: This transformation does not always carry the figure onto itself. It would result in a reflection of the trapezoid across lines, which would also change the orientation of the trapezoid.

C. A rotation of 90° clockwise about point P: This transformation ALWAYS carries the figure onto itself. A 90° clockwise rotation about point P will preserve the perpendicularity of lines s and r, the parallelism of "liner" to the bases, and the bisection properties. The resulting figure will be congruent to the original trapezoid.

D. A rotation of 180° clockwise about point P: This transformation does not always carry the figure onto itself. A 180° rotation about point P would change the orientation of the trapezoid, resulting in a different figure.

The joint PDF of X and Y is fx.x (x, y) = λ * exp(-λx) / x for 0 < y < x, and 0 elsewhere.

The joint probability density function (PDF) of X and Y can be obtained by multiplying the individual PDFs of X and Y, as they are independent random variables.

Given:

X ~ Exponential(λ), with mean 1 (λ = 1)

Y ~ Uniform(0, X), for 0 < y < x

To find the joint PDF, we first need to express the PDFs of X and Y.

PDF of X:

fX(x) = λ * exp(-λx) for x > 0 (Exponential distribution with parameter λ)

PDF of Y:

fY(y|x) = 1 / x for 0 < y < x (Uniform distribution on interval [0, x])

Now, we can find the joint PDF by multiplying these individual PDFs:

fx.x (x, y) = fX(x) * fY(y|x)

Substituting the PDFs:

fx.x (x, y) = (λ * exp(-λx)) * (1 / x)

fx.x (x, y) = λ * exp(-λx) / x for 0 < y < x

A price floor is a law that limits the minimum price at which a good, service, or factor of production can be sold while a price ceiling is a regulation that limits the maximum price at which a good, service, or factor of production can be sold

Price floors are commonly implemented to support producers, while price ceilings are typically put in place to protect consumers from higher prices that might result from shortages or monopolies.

Example of Price Floor:Agricultural subsidies are a common example of price floors. Government price floors ensure that farmers receive a minimum price for their crops.

If the market price of wheat falls below the government-established price floor, the government may buy the excess supply at the guaranteed price, ensuring that farmers are able to make a profit. If there is a price floor, the minimum price is set above the equilibrium price.

Hope this helps and have a happy valentines day

Mak brainliest please :)

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

We have to replace the values in the equation

Since the square of a negative number is a positive number, (-4)^2 = +16

The angle between the vectors a and b is approximately 48 degrees.

To find the angle between two vectors a and b, we can use the formula:

cos θ = (a · b) / (|a| |b|)

where a · b is the dot product of a and b, and |a| and |b| are the magnitudes of a and b, respectively.

First, let's find the dot product of a and b:

a · b = (i)(4) + (2j)(0) + (-2k)(-3) = 4 + 6 = 10

Next, let's find the magnitudes of a and b:

|a| = √(1^2 + 2^2 + (-2)^2) = √9 = 3

|b| = √(4^2 + 0^2 + (-3)^2) = √25 = 5

Substituting these values into the formula for cos θ, we get:

cos θ = 10 / (3 * 5) = 2/3

To find the angle θ, we can take the inverse cosine (cos^-1) of 2/3:

θ = cos^-1(2/3) = 48.19 degrees

Therefore, the angle between the vectors a and b is approximately 48 degrees.

a. f'(x) = 40x³

To find the derivative of f(x) = 10x⁴, we apply the power rule.

The power rule states that if f(x) = axⁿ, then f'(x) = naxⁿ⁻¹. Applying this rule, we get f'(x) = 4 * 10x³ = 40x³.

b. : f'(x) = 20 + 90x²

To find the derivative of f(x) = 20x + 30x³, we differentiate each term separately. The derivative of 20x is 20, and the derivative of 30x³ is 90x² (applying the power rule). Adding these derivatives, we get f'(x) = 20 + 90x².

r: f'(x) = (20x - 4x²)(5x - x²) + (10 + 2x²)(-2x + 5)

To find the derivative of f(x) = (10 + 2x²)(5x - x²), we apply the product rule. The product rule states that if f(x) = g(x) * h(x), then f'(x) = g'(x) * h(x) + g(x) * h'(x). Differentiating each term, we get f'(x) = (20x - 4x²)(5x - x²) + (10 + 2x²)(-2x + 5).

d.: f'(x) = 40x

To find the derivative of f(x) = 20x / (x²), we use the quotient rule. The quotient rule states that if f(x) = g(x) / h(x), then f'(x) = (g'(x) * h(x) - g(x) * h'(x)) / (h(x)²). In this case, g(x) = 20x and h(x) = x². After differentiating and simplifying, we obtain f'(x) = 40x.
