When X 3x² 1 is divided by x 1 then remainder will be?.
Answers
After solving, the remainder when [tex]-x+3x^2-1[/tex] is divided by x + 1 is 3.
In the given question, we have to find the remainder when [tex]-x+3x^2-1[/tex] is divided by x + 1.
The given polynomial is [tex]-x+3x^2-1[/tex].
We have to find the remainder of the polynomial when we divide this polynomial x + 1.
To find the polynomial we equate x+1 equal to zero to find the value of x.
x + 1 = 0
x = -1
Now putting x = -1 in the given equation [tex]-x+3x^2-1[/tex].
P(x) = [tex]-(-1)+3(-1)^2-1[/tex]
P(x) = 1 + 3×1 - 1
P(x) = 1 + 3 - 1
P(x) = 3
Hence, the remainder when [tex]-x+3x^2-1[/tex] is divided by x + 1 is 3.

Why is equivalence important in maths?.
Answers
Equivalence relations are important in maths because of the following parts,
The fundamental theorem of equivalence relations is basic theorem.In integration theoryIn case of equivalent fractionA relation R on a set A is called an equivalence relation if and only if the relation R is recursive, symmetric, and transitive. An equivalence relation is a relation on sets, and is generally represented by the symbol “~”. For example: "Equal to (=)" is the equivalence relation on any set of numbers A for all elements a, b, c ∈ A,
Reflexive: a = a ,
Symmetric: a = b ⇒ b = a and
Transitive: a = b, b = c ⇒ a = c.
This means that (=) is recursive, symmetric, and transitive. Equivalence relations are used in several areas of mathematics.
In integration theory, functions are considered "equal" if they differ only in a small set. in some respects. If the function is not identified in this way, some commonly used standards conditiondoes not satisfy || f || = 0 <=> f=0.
Two fractions are equivalent if they have the same decimal number. That is, if ad = b, a/b is equivalent to c/d. (One example is based on equivalence relations).To learn more about equivalence relation , refer:

How do you use the zero product property to solve a quadratic equation in factored form?.
Answers
Quadratic equations in factored form can be solved by using the Zero Product Property, which states that if the product of two numbers equals zero, then at least one of the values must also equal zero.
The Zero Product Property can be used to resolve any factored quadratic equation, such as (a + b)(a b) = 0. In accordance with the zero product property, if a+b=0, then either an or b must also be equal to zero. This essential characteristic allows us to solve equations like (x+2)(x-5)=0.
The zero product property states that if two quantities are added together and the result is zero, then one or both of the individual quantities must also be zero. You can solve this problem by rewriting it as (x + 3) (2 x 1) = 0.

Writing linear equations given two points can be a useful skill when graphing linear equations.
Write a linear equation that passes through the given two points?To write a linear equation given two points, you need to first find the slope of the line. You can do this by finding the change in the y-value and dividing it by the change in the x-value. From there, you can use the slope to solve for the y-intercept and write the equation.For example, if the two points are (3, 4) and (0,5), you would find the slope by calculating the change in the y-value (5-4 = 1) and dividing it by the change in the x-value (0-3 = -3).The slope would then be 1/-3, which can be simplified to -1/3. To solve for the y-intercept, you can plug in one of the points and solve for b. In this case, you would plug in (3, 4) and solve for b, giving you b = 5. Now that you have the slope and y-intercept, you can write the equation as y = -1/3x + 5.y = -1/2xy = 5/3x + 5/3y = 3/5x + 1y = -1/2x - 2y = 6/5x + 5y = -4/4x - 8y = -3/5x - 7/5y = -2x - 4y = 5/6x + 7y = -1/2x + 4To learn more about linear equation refer to:

Why does the operations subtraction and division Cannot be applied by commutative property and associative property?.
Answers
The commutative property and associative property do not hold for subtraction and division, as the end results are completely different after changing the order of numbers.
The commutative property deals with the arithmetic operations of addition and multiplication. It means that changing the order or position of two numbers while adding or multiplying them does not change the end result.
For example, 4 + 5 gives 9, and 5 + 4 also gives 9. The order of two numbers being added does not affect the sum. The same concept applies to multiplication too.
Thus, The commutative property and associative property do not hold for subtraction and division, as the end results are completely different after changing the order of numbers.

Answers
Answer:
B. Output = (2)(Input) – 3.
Step-by-step explanation:
The correct answer is B. Output = (2)(Input) – 3.
This is because the function is a linear function, and the slope is 2 and the y-intercept is -3.
You can see this by considering the difference in y for each pair of points and the difference in x for each pair of points.
For example, from (negative 1, 1) to (1, 2) the difference in y is 1 and the difference in x is 2.
This means the slope is 1/2 which is the same as 2, and the y-intercept is -3

The term "density" refers to the amount of volume (or physical space) occupied by an object or substance in relation to the amount of matter contained therein (its mass).
What is density ?
The quantity of things—which could include humans, animals, plants, or objects—in a given space is referred to as density. To determine density, divide the number of objects by the area's measurement. The number of people in a country divided by its area in square kilometers or miles is known as its population density.
The term "density" refers to the ratio between the volume (the amount of space taken up by an object or substance) and the amount of matter contained therein (its mass). The amount of mass per unit of volume is another method to define density. An object has a high density if it is both heavy and small.
By dividing the mass of an object by its volume, one may determine its density.
This means that if density is D, mass is M, and volume is V.
a)
M = 500 gms
40 cubic cm V
$D=$500/40

b)

how much water do you add to make this concentration? 25% sugar syrup using 15 g sugar
Answers
The amount of water to add is 45 grams
How to determine the amount of water to addFrom the question, we have the following parameters that can be used in our computation:
Sugar = 15 grams
Proportion of syrup = 25%
So organizing the information given in the statement we have that:
25% sugar syrup means it has 25% sugar and 75% waterAmount of sugar = 15g = 25%In this way, we can calculate the missing value for this percentage as:
25% of x = 15 grams
Express as decimal
So, we have
0.25 * x = 15
Divide both sides by 0.25
x = 60
This means that the total amount is 60 grams
If the syrup contains 25% of sugar, then 75% would be water (assume no other item is present)
So, we have
Water = 75% * 60g
Water = 45g
Hence, the amount is 45 grams

FX = -12x + 3
To determine the range of the function, start by graphing the equation.
The graph will be a line with a slope of -12 and a y-intercept of 3.
To find the range, we need to determine the y-values of the graph as x-values increase. Since the slope is negative, the y-values will decrease as x-values increase.

Due to the absence of an x in the issue, the y-intercept is -4. At the conclusion, it stands on its own and directs you to begin at (0,-4). The slope is -5/1 because the slope of the equation is toward the value of x in the equation.
How steep a slope does Y = - 5x 4 have?y = 5x - 4 has a 5 slope. The line's equation, y = 5x - 4, is expressed in the form y = mx + b, as you can see. It is therefore in slope-intercept form.

How do you calculate a function's slope and y-intercept?Y = mx + b, where m denotes the slope and b the y-intercept, is how the equation of the line is expressed in the slope-intercept form. We can see that the y-intercept of the line in our equation, y = 7 x + 4, is 4.
