Step-by-step explanation:

After 0 months, she still needs to pay the first $35. This means that this is her y-intercept, and in the formula “y=mx+b”, it would go in the “b” place. Then x would mean how many months have passed, so therefore 40 would go into the “m” place. If you put that together, it looks like “y=40x+35”.

Answer: x = 8, x = -2

Step-by-step explanation:

(x - 3)² = 25

Step 1: Take the square root on each side of the equation.

(x - 3)² = 25

√(x - 3)² = ±√25

Step 2: After taking the square root on each side of the equation, this allows you to solve for x.

x - 3 = ±5

Solution 1

x - 3 = 5

x = 5 + 3

x = 8

Solution 2

x - 3 = - 5

x = -5 + 3

x = -2

Another way to solve this problem is to multiply (x - 3)² using the FOIL methods (first, outer, inner, last) and then set it equal to 25.

(x - 3) (x - 3) = 25

x² - 3x - 3x + 9 = 25

The next step is to add like terms. After adding like terms, solve for x.

x² - 3x - 3x + 9 = 25

x² - 6x + 9 - 25 = 25 - 25

x² - 6x - 16 = 0

Last step is to factor x² - 6x - 16 = 0 so you can solve for the two solutions.

(x - 8) (x + 2) = 0

Solution 1

x - 8 = 0

x = 8

Solution 2

x + 2 = 0

x = -2

The measure of each Angle is 80, 50 and 50 degree.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Given:

<H= 4x- 20

and, <G = 2x

and, <I = 2x

Now, In triangle GHI using Angle Sum Property

Answer & Step-by-step explanation:

To get the range of the function y = 2x + 1, we need to determine the set of all possible output values (y) that the function can produce for the given domain.

When x = -2, y = 2(-2) + 1 = -3.

When x = 4, y = 2(4) + 1 = 9.

When x = 6, y = 2(6) + 1 = 13.

So, the output values (y) for the given domain { -2, 4, 6 } are -3, 9, and 13.

The original price of the love seat was $495.

Let

Original price of the love seat= x

New price= $396

Percentage discount= 20%

396 = x - (20% of x)

396 = x - 0.2x

396 = 0.8x

divide both sides by 0.8

x = 396 / 0.8

y' = (y-3)(y+3)exp(y)

This differential equation has equilibrium solutions at y=0 and y=3, and y' is positive for -inf < y < 0 and 3 < y < inf and negative for 0 < y < 3.

1. Set y′ = 0 to get the equilibrium solutions

y′ = 0 → y = 0 and y = 3

2. Find the sign of y′

y′ = (y-3)(y+3)exp(y)

For y < 0, y′ is positive

For 0 < y < 3, y′ is negative

For y > 3, y′ is positive

This differential equation has two equilibrium solutions at y=0 and y=3, meaning the value of y does not change when the equation is applied.

To determine the sign of the equation, we can look at the equation y′ = (y-3)(y+3)exp(y). For y < 0, y′ is positive. This means that when y is less than 0, the equation increases in value. For 0 < y < 3, y′ is negative. This means that when y is in between 0 and 3, the equation decreases in value. And for y > 3, y′ is positive. This means that when y is more than 3, the equation increases in value.

Overall, the equation behaves as expected: it increases when y is less than 0 and more than 3, and decreases when y is between 0 and 3. This is what we would expect in order for the equation to have the equilibrium solutions at y=0 and y=3.

The domains of the composite function (f/g)(4) and (f + g)(4) for f(x) = x² + 2x - 3 and g(x) = x² - 9 are equal to 3 and 28 respectively.

A function is composite when the co- domain of the first mapping is the domain of the second mapping

We shall evaluate the domains of the function (f/g)(4) and (f + g)(4) as follows:

(f/g) = (x² + 2x - 3)/(x² - 9)

by factorization of the right hand side;

(f/g) = (x - 1)(x + 3)/(x - 3)(x + 3)

(f/g) = (x - 1)/(x - 3)

(f/g)(4) = (4 - 1)/(4 - 3)

(f/g)(4) = 3

(f + g) = x² + 2x - 3 + x² - 9

(f + g) = 2x² + 2x - 12 {simplify like terms}

(f + g)(4) = 2(4)² + 2(4) - 12

(f + g)(4) = 28

Therefore, the domains of the composite function (f/g)(4) and (f + g)(4) for f(x) = x² + 2x - 3 and g(x) = x² - 9 are equal to 3 and 28 respectively.

Correct Answer: c. ordinal scale

What is the ordinal scale?

An ordinal scale is a type of measurement scale in which the data can be ranked or ordered based on the size or value of the measurement. The categories in an ordinal scale, such as "excellent," "very good," "good," and "poor," do not have equal intervals or a true zero point, so they cannot be used to perform mathematical operations. The main purpose of an ordinal scale is to order or rank the data based on relative position.

In this case, the restaurant's rating scale is an example of an ordinal scale because the customers are asked to indicate the quality of service on a scale with four categories, and the categories can be ranked in order from best to worst.

A directed graph can be used to determine whether a relation R on a finite set A is asymmetric or not by checking whether there is any pair of elements (a, b) in R such that both (a, b) and (b, a) are present in R.

If such a pair exists, then the relation is not asymmetric because it violates the condition for asymmetry, which states that for any (a, b) in R, (b, a) cannot be in R.

In the directed graph, this means that there is a directed edge from a to b and also a directed edge from b to a. This would result in a cycle in the directed graph, which is not allowed in an asymmetric relation.

If there are no such pairs in R, then the relation is asymmetric, and the directed graph will not contain any cycles. Therefore, the directed graph can be a helpful tool to quickly determine if a relation is asymmetric or not, especially for larger sets A.

Answer: The transformation matrix R for a rotation of 120° about an axis from the origin through the point (1,1,1) can be calculated using the formula:

R = I + (sin(θ))U + (1-cos(θ))UU'

where θ is the angle of rotation (120° in this case), I is the identity matrix, U is a skew-symmetric matrix, and U' is its transpose. The skew-symmetric matrix can be calculated as follows:

U = [0, -z, y; z, 0, -x; -y, x, 0]

where x, y, and z are the components of the vector (1,1,1) that defines the axis of rotation.

Plugging in the values and simplifying, the transformation matrix R is:

R = [ cos(120°), -sin(120°), 0; sin(120°), cos(120°), 0; 0, 0, 1 ]

Note: cos(120°) = -1/2 and sin(120°) = √(3)/2.

A central angle in a circle measures 52 degrees. 13° is the measure of an inscribed angle that intercepts the same arc.

An arc's inscribed angle is the angle that it occupies at any given point on the circle. The angle created when two chords cross on a circle's interior is known as a "inscribed angle" in geometry. The angle formed at a specific location on the circle by two specified points on the circle can also be used to define it. Two chords of the circle that share an endpoint define an inscribed angle in the same way.

Half of the size of the central angle that corresponds with the intercepted arc makes up the size of an inscribed angle. An inscribed angle's measurement is equal to half of its intercepted arc's measurement.

Thus, central angle = 52°

so, intercepted arc = 26°

hence, inscribed angle = 13°

We have shown that for any eigenvalue λ of A, 1-λ is an eigenvalue of -A. So, the eigenvalues of -A are 1-λ1, 1-λ2, ..., 1-λn, where λ1, λ2, ..., λn are the eigenvalues of A.

Eigenvalues are scalar values that are associated with a linear transformation of a matrix and are used to represent the behavior of a linear system. They represent the factor by which a linear transformation scales the direction of a vector. Eigenvalues play an important role in many areas of mathematics, including linear algebra, physics, engineering, and statistics. If a matrix A has an eigenvector x and an eigenvalue λ, then A can be represented as a scalar multiplication of x by λ: A x = λ x. The eigenvalues of a matrix can be used to determine its stability, to find the diagonalization of the matrix, and to determine the eigenvectors that represent the most important directions of a linear transformation.

The eigenvalues of a matrix A are scalars that satisfy the equation Av = λv, where v is a non-zero eigenvector and λ is the corresponding eigenvalue. If λ is an eigenvalue of A, then 1-λ is an eigenvalue of -A.

To see why this is true, let's consider an eigenvector v of A with eigenvalue λ. Then, Av = λv. We can multiply both sides of this equation by -1 to obtain:

-Av = -λv

Now, we can substitute -A for A and 1-λ for λ:

(-A)v = (1-λ)v

Thus, we have shown that for any eigenvalue λ of A, 1-λ is an eigenvalue of -A. So, the eigenvalues of -A are 1-λ1, 1-λ2, ..., 1-λn, where λ1, λ2, ..., λn are the eigenvalues of A.
