The correct option is C. (0, 1, 2); function. The domain of the function is (0, 1, 2).

For the given question;

The relation is;

(x, y) =  {(0, 0), (1, 1), (2, 0)}

Take out the values for x.

x = {0, 1, 2}

The above set indicates that the x-values begin at 0 and end at 2.

As a result, the domain is {0, 1, 2}.

To be a function, all of the relation's y-values must refer to different x-values.

Since all y-values possess unique x values, we can say that the provided relation is a function.

Therefore, the given relation defines a function with domain of {0, 1, 2}.

According to the question, Pat wants to buy four donuts.

Let us assume donuts should be represented as ’D’. And the four donuts can be represented as ‘DDDD’.

Now, as per the question, there are three types of donuts and they are glazed, chocolate and powdered. Divide the donut into two parts as first one is glazed, second is chocolate and third is powdered. And the quantity of glazed is one, chocolate is two and powdered is one. And the total object is six. Therefore, the probability can be written as:

[tex]P(E) = \frac{6P2}{2} = 15 ways.[/tex]

Hence, there are [tex]15[/tex] ways to select the donuts.

According to the given data the non - degenerated closed interval in r is calculated as [tex]\int\limits^t_s[/tex]f(t) - f(s).

Any set that only contains one real number is known as a degenerate interval (i.e., an interval of the form [a,a]).  an interval is measured in terms of numbers. An interval is any integer that falls between two specific numbers. This range encompasses all real numbers between those two. Real numbers can be any number anyone can think of. A degenerate interval is any set that contains only one real number (i.e., an interval of the form [a, a]). The empty set is included in this definition by some authors. A suitable interval is one that is either empty or degenerate and has an infinite number of elements.

f(x[tex]_r[/tex]) - f(x[tex]_r[/tex]₋₁)  = F' (e[tex]_r[/tex])(x[tex]_r[/tex] - x[tex]_r[/tex]₋₁)

By summating the equation it becomes.

Slack of a3 is 6 weeks.

Slack variables are variables that are introduced to an inequality constraint in an optimization problem to change it into an equality. An inequality constraint is replaced by an equality requirement and a non-negativity constraint on the slack variable when a slack variable is introduced. In particular, slack variables are employed in linear programming. The slack variable, like the other variables in the augmented constraints, can only have positive or zero values because of the simplex method. A constraint is binding at a certain candidate solution if its associated slack variable is zero because it limits the modifications that can occur after that.

Answer:

A.

Step-by-step explanation:

Due to the absolute value markers on either side of the equation, there will be no negative numbers that will equal f(x). Therefore, the range cannot equal all real numbers, only all positive real numbers.

The equation of the line is (y + x = 0).

The slope of a line indicates its steepness in addition to its direction.

m = Δy/Δx

where, m is the slope

And, tan θ = Δy/Δx

The above tan is also known as the line's slope.

The slope of a line can also be calculated just using two straight line points. The slope of line formula could then be used with two point coordinates.

Now, in response to the question;

P₁ = (x₁, y₁)

P₂ = (x₂, y₂)

Then slope will be;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

Consider the values given in the question;

(x₁, y₁) = (-1,-3) and,

(x₂, y₂) = (1,-5).

Put the values in the formula of the slope;

Slope = m = (-5 + 3)/(1 + 1)

m = -2/2

m = -1

Thus, the slope of the line is -4.

Now, the formula for finding the equation of line using the two points system.

(y - y₁) = m(x - x₁)

(y + 3) = (-1)(x + 1)

y + 3 = -x - 1

y + x + 4 = 0.

Therefore, the equation of the line using two point system is calculated as (y + x = 0).

Let's see a few examples to understand the statement given in the question.

Example 1:

Find the sum of 75.5 + (58.231 + 24.5)

Hence , the sum of 75.2+(57.376+24.8) is 158.231.

75.5 + (58.231 + 24.5)

= 75.5 + (24.5 + 58.231) (using the commutative property of addition)

= (75.5 + 24.5) + 58.231 (using the associative property of addition)

= 100 + 58.231 (by looking at the first two numbers, it is easier to say that the sum is 100.)

= 158.231 (you can write this answer directly without doing any calculation)

Therefore, the sum of 75.2+(57.376+24.8) is 158.231.

Example 2:

Find the product of (25 × 2) × 50

Hence , the product is 2500 .

(25 × 2) × 50

= 25 × (2 × 50) (using the associate property of multiplication)

= 25 × 100

= 2500 ( we can simply add to zeros at the end if an integer number is multiplied by 100.)

Therefore, the product of (25 × 2) × 50 is 2500.

Step-by-step explanation:

The slope of the line represented by the equation -5x + 2y = 10 is slope = -5/2 and y intercept= -5

In order to answer the question, we must first simplify the given linear equation so that it may be expressed as a regular linear equation with slope and intercept. A linear equation's slope intercept form is y=mx+b , where "m" denotes the line's slope and "b" its y-intercept. The value of y = 0 must then be entered for the x-intercept, and the value of "x" must then be determined. We will obtain all necessary values in this manner.

By slope-intercept form equation of the line:

y=mx+b

The advantage of the equation in this form is that m and b can be derived 'easily'

Rearrange -5x-2y = 10 in this form.

-2y=5x+10

y=-5/2x+-10/2

y=-5/2x-5

slope = -5/2

y intercept= -5
