Wich number is prime 25,27, or 29

The given system of equations do not have a solution since their related line equations have the same slope.

The given system of equations is:

-x + 5y = 3   .......... (1)

2x - 10y = 4   ........(2)

In Equation (1), add both sides by (-5y)

-x + 5y + (-5y) = 3 + (-5y)

-x = -3 - 5y

Multiply by (-1)

x = 3 + 5y

Substitute x = 3 + 5y into equation (2)

2x - 10y = 4

2.(3 + 5y) - 10y = 4

6 + 10y - 10y = 4

6 = 4 (False)

Since the last equation is false, we might suspect that the given system of solution does not have solutions.

We need to check the slope of both equations:

-x + 5y = 3

⇒ 5y = x + 3

⇒ y = 1/5 x + 3/5

2x - 10y = 4

⇒ -10 y = -2x + 4

⇒ y = (2/10) x - 4/10

⇒ y = 1/5 x - 2/5

We can see that both equations have the same slope, i.e. 1/5.

Hence, they do not have solutions since the lines are parallel to each other.

The equation of the circle that passes through the point (-5 , 0) and has a center located at the origin is x^2 + y^2 = 25

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-5 , 0).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-5 - 0)^2 + (0 - 0)^2

radius= √25

radius = 5

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (0 , 0)

r = 5

(x - 0)^2 + (y - 0)^2 = 5^2

x^2 + y^2 = 25

The equation of the line in standard form passing through the points (2 , 3) and (4 , 5) is x - y = -1.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant.

Given two points, (2 , 3) and (4 , 5), use the two-point form to generate the equation of the line.

y - y2 = [(y2 - y1)/(x2 - x1)] (x - x2)

y - 5 = [(5 - 3)/(4 - 2)](x - 4)

y - 5 = (2/2)(x - 4)

y - 5 = x - 4

To write the equation in standard form, arrange the variable(s) in one side and the constant(s) in the other.

y - 5 = x - 4

x - y = -5 + 4

x - y = -1

According to the given question.

We have an expression 5(a -2b) -3(a -2b).

As we know that, the simplification of an expression means to write an equivalent expression which contains no similar terms.

Therefore, the simplificantion of the expression  5(a -2b) -3(a -2b) is given by

5(a -2b) -3(a -2b)

= 5a - 10b - 3a + 6b         (by distributive rule)

The eighth term of the given geometric sequence is: [tex]\frac{5}{64}[/tex]

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Given: 10, 5, 2.5, ...

Here, [tex]\frac{5}{10}=\frac{2.5}{5}=\frac{1}{2}[/tex]

Thus, the given geometric sequence has a₁ = 10 and r = 1/2

The nth term of a geometric sequence is given by: [tex]a_n=a_1(r^{n-1})[/tex]

The given statement exists true that "The orthocenter of a right triangle is always found at the right angle's vertex".

The orthocenter is the point at which the triangle's three altitudes cut or intersect. The altitude is the line drawn from the triangle's vertex that is perpendicular to the opposite side. There are three altitudes because the triangle has three vertices and three sides.

The given statement exists true that "The orthocenter of a right triangle is always located at the vertex of the right angle".

The altitudes from the two non-right vertices (A and B) will always be the legs of the triangle, which intersect at the vertex containing the right angle, as shown in the right triangle below (C). Because the altitude to the triangle's hypotenuse originates at the vertex, the three altitudes (the red rays) intersect there. As a result, the vertex of a right triangle is always the orthocenter.

Answer:

23 cm, 25 cm

Step-by-step explanation:

Let the Width be W cm.

Since the Length and Width are consecutive odd integers we know that the length:

Length = (W + 2) cm

Perimeter of Rectangle = Sum of all sides = 2 x Length + 2 x Width

So rewriting the perimeter , we have:

2W + 2(W+2) = 96 cm

Now lets solve for W to get the width.

2W + 2W + 4 = 96 cm

4W + 4 - 4 = 96 - 4

4W = 92 cm

W = 23 cm

Next, we know that the length = (W + 2) cm

Therefore the length = 23 + 2 = 25 cm

The following set of numbers, 44, 46, and 91, cannot be the measures of the sides of a triangle.

A triangle is a polygon with three sides and three vertices.

To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.

let a = 44, b = 46, and c = 91

a + b > c     44 + 46 > 91     90 > 91     False

a + c > b     44 + 91 > 46     135 > 46     True

b + c > a     46 + 91 > 44     137 > 44     True

If at least one of these three statements is not true, then the set of numbers is not a valid measure of the sides of a triangle.

Hence, the set of numbers 44, 46, and 91 can not be the measure of the sides of a triangle.

Permutation:

Permutation is the way arranging the objects or numbers in order.

It can be calculated using the formula,

ₙPₓ = n!/(n - x)!

where,

ₙPₓ   = number of combinations

n = total number of objects in the set

x = number of choosing objects from the set

Given,

Augusto has 3 pockets and 4 different coins.

Here we need to find how many ways can he put one coin in each pocket.

We know that,

Augusto has 4 different coins that he is choosing 3 at a time.

So, it can be written as,

The number of ways to put one coin in each pocket is the permutation of 4 coins taken 3 at a time.

Therefore, the number of permutations is calculated as,

=> ₄P₃ = 4! / (4 - 3)!

=> ₄P₃ = 4! / 1!

=> ₄P₃ = 4 x 3 x 2 x 1

=> ₄P₃ = 24

FA recursive formula allows us to find each term in the geometric sequence using the previous term. Each new term is the product of the common ratio for that sequence and the previous term of that unknown or to-be-found term. If the common ratio is 9, each term is nine times the previous term.

The general term for the geometric sequence is

an= a1 * r ^ (n-1)

Where "an" refers to the nth term of the sequence, a1 is the first term known as the sequence, and r is the common ratio, n is its position or the number.

A polynomial is an algebraic expression that consists of variables and constants connected by arithmetic operations.

Given the polynomial function f(x) = (x - a)(x - b) and if we observe the graph we can see that the polynomial has two roots,

one at x = 1 and another at x = -1.

If x = 1 is a root of this polynomial we can write this in factor form as.

x = 1.

x - 1 = 0

And

x = -1.

x + 1 = 0.

∴ f(x) = (x - 1)(x + 1).

f(x) = x² - 1², So it is a quadratic function.

The equation of the line 4x = 2 + y expressed in slope-intercept form is y = 4x - 2 with a slope equal to 4.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

Given the equation of the line 4x = 2 + y, express it in slope-intercept form by isolating the variable y in one side.

4x = 2 + y

y = 4x - 2

Hence, the equation of the line in slope-intercept form is y = 4x - 2 where the slope, m, is equal to 4.

The geometric mean of two positive numbers can be determined by multiplying the numbers and taking their square root.

Geometric mean is the mean or average value which expresses the central tendency of the set of numbers by taking root of the product of their values. In other words, we multiply the n values and take the nth root of the numbers. Geometric mean can also be expressed as the nth root of the product of n numbers.

The formula for finding geometric mean is:

GM = n√ x1*x2*x3…xn

Let the two terms be 2 and 8. Hence, x1=2, x2=8 and n=2.

GM = √2*8=√16=4
