Answer: y=-0.4x+20.2
Step-by-step explanation:
\(5x-2y=6\\5x-2y+2y=6+2y\\5x=6+2y\\5x-6=6+2y-6\\5x-6=2y\)
Divide both parts of the equation by 2:
\(\displaystyle\\\frac{5x-6}{2}=y\\\\\frac{5}{2} x-3=y\)
Coordinates of the intersection point of the equations:
\(\displaystyle\\y=\frac{5}{2}x-3 \ and\ x=8\ are:\)
\(\displaystyle\\x=8\\Hence,\\y=\frac{5}{2} (8)-3\\\\y=\frac{5*8}{2} -3\\\\y=\frac{5*4*2}{2}-3\\\\y=5*4-3 \\\\y=20-3\\\\y=17\\Thus, (8,17)\)
\(\displaystyle\\The\ slope\ \perp=-\frac{1}{\frac{5}{2} } \\\\The\ slope\ \perp=-\frac{2}{5}\)
\(\displaystyle\\-\frac{2}{5} =\frac{y-17}{x-8}\)
Multiply both parts of the equation by (x-8):
\(\displaystyle\\-\frac{2}{5}(x-8)=y-17\\\\-\frac{2}{5} x+\frac{2*8}{5} =y-17\\\\-\frac{2}{5}x+\frac{16}{5} =y-17\\\\ -0.4x+3.2=y-17\\\\ -0.4x+3.2+17=y-17+17\\\\-0.4x+20.2=y\)-

Solve the equation for v.
0.5v + 0.06 < 3.46
v > 1.8
v < 1.8
v > 6.8
v < 6.8
Answer:
\(\boxed{\tt v < 6.8}\)
Step-by-step explanation:
\(\tt 0.5v+0.06 < 3.46\)
Multiply both sides by 100:-
\(\tt 0.5v\times\:100+0.06\times\:100 < 3.46\times\:100\)
\(\tt 50v+6 < 346\)
Subtract 6 from both sides:-
\(\tt 50v < 340\)
Divide both sides by 50:-
\(\tt \cfrac{50v}{50} < \cfrac{340}{50}\)
\(\tt v < \cfrac{34}{5}\)
Or
\(\tt v < 6.8\)
Therefore, your answer is v < 6.8!!! :)

Spin a spinner with three equal sections colored red, white, and blue. What is P(yellow)?
a.100%
b.66%
c.33%
d.0%
The probability of getting the color yellow when spinning a spinner with three equal sections colored red, white, and blue is 0%. Therefore, the correct answer is d) 0%.
Since the spinner has three equal sections colored red, white, and blue, and there is no section labeled yellow, it is not possible to obtain the color yellow when spinning the spinner. Each section has an equal chance of being landed on, but none of them represent the color yellow. Therefore, the probability of getting the color yellow is 0%. It's important to note that probability represents the likelihood of an event occurring, and in this case, the event of landing on the color yellow is not possible given the given information about the spinner. Therefore, the probability is 0%.

Let A = X 0 where x is a real number. Answer the following questions. 2 0 -X 0 (1) Find all eigenvalues of A and the corresponding eigenvectors. (2) Find an expression for An for any positive integer n. 1 (3) Find an expression for A". matrix defined by n! An. 0 -X - n=1
The matrix A is given by A = [X 0; 2 0]. The task is to find the eigenvalues and corresponding eigenvectors of A, determine an expression for An for any positive integer n, and find an expression for the matrix A" defined by n! An.
To find the eigenvalues and corresponding eigenvectors of A, we solve the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I am the identity matrix.
The characteristic equation for A is:
|X-λ 0 |
|2 -λ| = 0
Expanding the determinant and solving for λ, we get two eigenvalues:
λ₁ = X and λ₂ = -X.To find the corresponding eigenvectors, we substitute each eigenvalue back into the equation (A - λI) * v = 0, where v is the eigenvector.
For λ₁ = X:
|X-X 0 |
|2 -X| * v₁ = 0
Simplifying, we get the equation -2v₁ + 2Xv₂ = 0, where v₂ is a free variable. Therefore, the eigenvector corresponding to λ₁ = X is v₁ = [1, 2X].
For λ₂ = -X:
|X+X 0 |
|2 X| * v₂ = 0
Simplifying, we get the equation 2v₃ + 2Xv₄ = 0, where v₄ is a free variable. Thus, the eigenvector corresponding to λ₂ = -X is v₂ = [1, -X].To find an expression for An for any positive integer n, we can diagonalize matrix A. As we found earlier, A has two distinct eigenvalues X and -X. Diagonalizing A, we express it as A = PDP⁻¹, where D is the diagonal matrix containing the eigenvalues and P is the matrix of corresponding eigenvectors.
Since A has two eigenvalues, we have:
D = |X 0|
|0 -X|
P = |1 1 |
|2X -X|
Therefore, An = P Dⁿ P⁻¹. Substituting the values of D and P, we can find the expression for An. Finally, to find an expression for the matrix A" defined by n! An, we multiply the matrix An by n!.
A" = n! An
Substituting the expression for An, we get:
A" = n! P Dⁿ P⁻¹
Here, n! can be multiplied by the diagonal elements of Dⁿ, resulting in:
A" = |n!Xⁿ 0 |
|0 (-n! X)ⁿ|
In summary, the eigenvalues of matrix A are X and -X, with corresponding eigenvectors [1, 2X] and [1, -X]. An expression for An is obtained by diagonalizing matrix A and raising the diagonal matrix D to the power of n. The matrix A" is defined by n! An is given by |n! Xⁿ 0 | |0 (-n!X)ⁿ|.

Given:
The figures of triangles and their mid segments.
To find:
The values of n.
Solution:
Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.
11.
It is given that:
Length of mid-segment = n+8
Length of parallel side = 6n
Using mid-segment theorem, we get
\(n+8=\dfrac{1}{2}(6n)\)
\(n+8=3n\)
\(8=3n-n\)
\(8=2n\)
Divide both side by 2.
\(\dfrac{8}{2}=n\)
\(4=n\)
Therefore, the value of n is equal to 4.
12.
It is given that:
Length of mid-segment = 5n
Length of parallel side = 8n+10
Using mid-segment theorem, we get
\(5n=\dfrac{1}{2}(8n+10)\)
\(5n=4n+5\)
\(5n-4n=5\)
\(n=5\)
Therefore, the value of n is equal to 5.

In step 3, we have the following equation:
-8x - 42 = -22
Simon applied the addition property of equality by adding 42 to both sides of the equation to get -8x = 20 in step 4.
Thus:-8x - 42 + 42 = -22 + 42
-8x = 20

Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.
To determine the amount of taxable income for Aaron Rentz in 2020, we need to consider his wages, interest income, and any deductions or credits he may be eligible for.
From the given information, Aaron has $900 of wages and $1,400 of interest income.
In 2020, the standard deduction for a single individual was $12,400. Since Aaron is a qualifying child of his parents, he may not be able to claim his own personal exemption.
To calculate Aaron's taxable income, we subtract the standard deduction from his total income:
Taxable Income = Total Income - Standard Deduction
Taxable Income = $900 + $1,400 - $12,400
Taxable Income = $2,300 - $12,400
Taxable Income = -$10,100
Since Aaron's taxable income is negative (-$10,100), it means that he does not have any taxable income.

A) L = √56
B) L=-√56
C) L=-14√56
D) L = 14√56
The length of the vector function F(t) over the interval -6 ≤ t ≤ 8 is D) L = 14√56.
The length of the vector function F(t) = <3 - 4t, 6t, -(9 + 2t)> from -6 ≤ t ≤ 8, we need to calculate the integral of the magnitude of the derivative of F(t) with respect to t over the given interval.
The magnitude of a vector v = <x, y, z> is given by ||v|| = √(x² + y² + z²).
First, let's find the derivative of F(t):
F'(t) = <-4, 6, -2>
Next, let's find the magnitude of F'(t):
||F'(t)|| = √((-4)² + 6² + (-2)²)
= √(16 + 36 + 4)
= √56
Now, we can calculate the length of F(t) over the interval -6 ≤ t ≤ 8 by integrating ||F'(t)|| with respect to t:
L = ∫(√56) dt
= √56 ∫dt
= √56 × t + C
Evaluating the integral over the given interval:
L = √56 × t + C| (-6)⁸
= √56 × (8 - (-6))
= √56 × 14
= 14√56
Therefore, the length of the vector function F(t) over the interval -6 ≤ t ≤ 8 is 14√56.

The area of the parallelogram with vertices a(-2, 5), b(0, 8), c(4, 6), and d(2, 3) is 14 square units.To find the area of a parallelogram with the given vertices, we can use the formula:
Area = |(x1y2 + x2y3 + x3y4 + x4y1) - (y1x2 + y2x3 + y3x4 + y4x1)| / 2
Let's calculate the area using the provided vertices:
a(-2, 5), b(0, 8), c(4, 6), and d(2, 3).

Area = |((-2)(8) + (0)(6) + (4)(3) + (2)(5)) - ((5)(0) + (8)(4) + (6)(2) + (3)(-2))| / 2
Simplifying:
Area = |(-16 + 0 + 12 + 10) - (0 + 32 + 12 - 6)| / 2
= |6 - 34| / 2

a circle of radius $2$ has center at $(2,0)$. a circle of radius $1$ has center at $(5,0)$. a line is tangent to the two circles at points in the first quadrant. what is the $y$-intercept of the line?
The y-intercept of the line is -4.
The circles have centers at (2,0) and (5,0) with radii 2 and 1, respectively. The tangent line touches the circles at points in the first quadrant. Let the tangent points be A and B for the circles with radii 2 and 1, respectively.
Since the tangent line touches the circles at points A and B, the radii connecting the centers to these points are perpendicular to the tangent line. Thus, the triangle formed by the centers of the two circles and the tangent points is a right triangle with the right angle at point A.
Let C be the intersection of the tangent line and the y-axis (y-intercept). The slope of line AC is (0 - 2) / (2 - 0) = -1. Since line AC is perpendicular to the tangent line, the slope of the tangent line is the negative reciprocal of -1, which is 1.
Now we can use the point-slope form of a line, y - y1 = m(x - x1), using point B (5,1) as (x1, y1) and m = 1 (slope). So, y - 1 = 1(x - 5). Simplifying, we get y = x - 4.
The y-intercept occurs when x = 0, so plugging in x = 0, we have y = 0 - 4 = -4.
Therefore, the y-intercept of the line is -4.

The y-intercept of the line that is tangent to two circles with centers at points (2,0) and (5,0) and with radii of 2 and 1 respectively is approximately 4.6.
Explanation:
The line tangent to both circles will form a right triangle with the centers of the two circles. The distance between the centers of the two circles (i.e., the base of the triangle) is 3 units (from point (2,0) to point (5,0)).
We know that the hypotenuse of this right triangle is the radius of the larger circle plus the radius of the smaller circle, i.e., 3 units. So, our right triangle has both base and the hypotenuse equal to 3 units making it a equilateral triangle. Therefore, the height/altitude of the triangle equals to √(3² - 1.5²) = √(9 - 2.25) = √6.75 ≈ 2.6.Since the tangent point in the first quadrant of the circle of radius 2 is 2 units above the x-axis, the y-intercept of the tangent line is (2+2.6)=4.6.

Scalar multiplication of a vector written in terms of i and j
ex:
v = 5i + 4j
Find: 6v
Find: -3v
The value of vector 6v is equal to 30i + 24j and value of vector -3v is equal to -15i - 12j.
Scalar multiplication of a vector written in terms of i and j means multiplying a vector by a scalar value, which scales the vector's magnitude while retaining its direction. To perform scalar multiplication of a vector, we simply multiply each component of the vector by the scalar value.
For example, suppose we have a vector v = 5i + 4j. To find 6v, we multiply each component of v by 6 to get 6v = (65)i + (64)j = 30i + 24j.
Similarly, to find -3v, we multiply each component of v by -3 to get -3v = (-35)i + (-34)j = -15i - 12j.
In both cases, we are scaling the original vector v by a factor of 6 and -3, respectively. The resulting vectors have the same direction as v, but their magnitudes are scaled accordingly.
