y = 3x – 2 is the equation of the line which passes through 1/3 and 2 5 with slope.

We can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope and b is the y-intercept. We know one point on the line, which is (1/3, 2.5). We can calculate the slope by calculating the rise (change in y) divided by the run (change in x), which is (2.5 - 0) / (1/3 - 0) = 2.5 / 0.33 = 7.5. Therefore, the equation of the line is y = 7.5x + b. To solve for b, we can substitute in our point, (1/3, 2.5) into the equation. We get 2.5 = 7.5(1/3) + b, or 2.5 = 2.5 + b. Therefore, b = 0, and the equation of the line is y = 7.5x + 0, or y = 7.5x.

The option which says Angle 2 and Angle 3 are Supplementary is the best statment that describes the Alternate Exterior Angle Theorem.

What is an Exterior Angle?

An Exterior Angle is the angle formed by a polygon's side and an extended neighbouring side; an angle generated by a transversal as it cuts one of two lines and located on the line's outside.

Solution:

Using the Alternate Exterior Angle Property we can say

Adjecent Angle of Angle 2 and Angle 3 are equal

Also, Angle 2 + Adjecent Angle of Angle 2 = 180

So, we can write Angle 2 + Angle 3 = 180

The probability that the coin will land heads up on the first flip, tails up on the second flip, and tails up on the third flip is (1/8).

If we toss a coin, we have two possible outcomes: head or tail. Now:

P(E) = Favourable outcomes / Total outcomes

      = 1/2

As per the question, we need heads on the first throw and tails on the next two throws. We know that for independent events:

P(A∩B∩C) = P(A)*P(B)*P(C)

Let A be the event of getting head on the first throw and B and C be events of getting tails on the second and third throws of dice respectively.

P(A) = P(B) = P(C) = 1/2

So, P(A∩B∩C) = (1/2)*(1/2)*(1/2) = 1/8

Answer:

Step-by-step explanation:

We first rewrite the terms of 48x² +38x + 5 to 48x² + 8x + 30x + 5

We then regroup terms into two proportional parts: (48x² +8x) + (30x + 5)

Factor the expression: 8x(6x + 1) + 5(6x + 1)

We then factor 8x(6x + 1) + 5(6x + 1) to (6x + 1)(8x + 5)

Now that we know (ax + b) and (cx + 1) is (6x + 1)(8x + 5) we just need to apply the numbers to their corresponding letters:

A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle between them, divided by two.

We have the triangle ABC.

Where c = 22ft, a = 18ft and b = 20ft

Law of Cosines:

The theorem that proves that the triangles are congruent is the Side-Side-Side (SSS) Congruence Theorem.

The Side-Side-Side (SSS) Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This theorem is useful for proving that two triangles are congruent without having to use angles. The SSS Congruence Theorem is a useful tool for solving geometry problems involving triangles. It can be used to find the unknown side length of a triangle given the lengths of the other two sides, or in more complicated proofs involving multiple triangles. This theorem is also helpful in determining the area of a triangle, as the area is proportional to the product of the lengths of the sides.

The function that represents the graph will be y = 1 - 2x in interval (∞, 2], y = -3 in interval [2, 3), y = -2 at x = 3, and y = 2(x - 4)² - 2 in interval (3, ∞).

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

From the graph, the equation of the line that passes through (0, 1) and (2, -3) is given as,

(y - 1) = [(1 + 3) / (0 - 2)](x - 0)

y - 1 = -2x

y = 1 - 2x, (∞, 2]

In intervals [2, 3), the equation is

y = - 3

At x = 3, the value of y is -1.

The vertex of the parabola is at (4, -2). Then the parabolic function is given as,

y = a(x - 4)² - 2

The equation is passing through (0, 5), then we have

Answer:

The correct equations are 2x +3y=100 and x+y=48. These equations can be used to find the number of multiple-choice and free response questions on the test. The first equation, 2x +3y=100, shows that the total number of points for the multiple-choice questions (2x) plus the total number of points for the free response questions (3y) equals 100. The second equation, x+y=48, shows that the total number of multiple-choice and free response questions on the test is equal to 48. These equations can be solved simultaneously to find the values of x and y.

Yes. The matrix A-2I is invertible because 2 is an eigenvalue for matrix A.

When the matrix (transformation) is applied to some vectors (eigenvectors), the eigenvalues of the matrix are scalars. In other words, if A is a square matrix of order n x n and v is a non-zero column vector of order n x 1, and Av = v (the product of A and v is just a scalar multiple of v), then the scalar (real number) is called an eigenvalue of the matrix A that corresponds to the eigenvector v.

The eigenvalues can be determined by formula,

[tex]|A-\lambda I|=0[/tex]

Where, [tex]\lambda[/tex] = eigenvalues.A square matrix with an inverse is known as an invertible matrix. A square matrix is said to be invertible if and only if the determinant is not equal to zero. In other words, a 2 x 2 matrix is only invertible if its determinant is not zero.

Given,

A is a 4x4 matrix whose eigen values are λ=1,2,3,4

we need to determine that A-2I is invertible or not.

We know that 2 is an eigen value of matrix A, so, if we substitute 2 to find determinant of A-2I, then we will get zero as answer.

So, when determinant of A-2I is zero then the matrix is invertible.

Answer:

To use coordinates on a coordinate grid, you first need to determine the scale of the grid, which is represented by the proportion M=24R. This means that for every 24 units on the grid, the corresponding real-world distance is equal to R units.

Once you have determined the scale of the grid, you can use the coordinates to locate points on the grid. To do this, you will need to know the coordinates of at least one point on the grid, which is known as the origin. The origin is typically represented by the coordinates (0,0).

To find the coordinates of a point on the grid, you can use the following steps:

For example, if you wanted to find the coordinates of a point that is 5 units to the right of the origin and 3 units above the y-axis, the coordinates of the point would be (5, 3).
