The best estimate of the solution to the system of equations will be (1, 4). Then the correct option is C.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of the equations is given below.

2x + 3y = 12            ...1

4x + 2y = 10           ...2

Divide the equation 2 by 2, then we have

2x + y = 5            ...3

Subtract equation 3 from equation 2, then we have

2x + 3y - 2x - y = 12 - 5

2y = 7

y = 3.5

y ≈ 4

Then the value of 'x' is calculated as,

2x + 3.5 = 5

2x = 1.5

x = 0.75

x ≈ 1

The best gauge of the answer for the arrangement of conditions will be (1, 4). Then, at that point, the right choice is C.

As per the tangent formula, the distance does the laser spot on the wall move if the mirror is rotated by 10 is 2.9m

While we looking into the given question we have identified the following values,

Previous distance = 9.5

And the angle = 30 degrees

Rotated angle = 10 degrees

And the distance is considered as x.

Then as per the tangent formula, it can be written like the following,

=> tan 30/9.5 = tan 10/x

When we apply the tangent value, then we get,

=> 0.5773/9.5 = 0.1763/x

When we perform the cross multiplication, then we get,

=> 0.5773x = 9.5 x 0.1763

=> 0.5773x = 1.6749

Then the value of x is obtained as,

=> x = 1.6749/0.5773

=> x = 2.9012

The fraction 2.666666666667 equals   [tex]\frac{8}{3}[/tex] .

A fraction is used to represent a portion/part of something larger. It symbolises the equal parts of the whole. A fraction is comprised of two components the numerator and the denominator. The top number is referred to as that of the numerator, and the bottom number is known as the denominator. The denominator specifies the total number of equal parts in a whole, whereas the numerator describes the number of equal parts taken.

1. Assume that x = 2.666667 (1)

2. Six is the repeating digit.

To the left of the decimal point, put the repeating digit.

In this instance, multiply the decimal point by 10 to move it one place to the right.

Thus,

(x = 2.666667) * 10

Equation 10x = 26.66667 (2)

4. Take Eq. (1) away from Eq (2)

10x - x = 26.66667 - 2.666667

9x = 24

9 divided by both sides

x = [tex]\frac{24}{9}[/tex] or [tex]\frac{8}{3}[/tex]

Answer:

g(x) = f(x) + 4 → Graph #5

h(x) = f(x + 4) → Graph #6

k(x) = f(x) - 4 → Graph #4

m(x) = f(x - 4) → Graph #3

Step-by-step explanation:

g(x) = f(x) + 4 → Graph #5

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) up by 4.

⭐ Graph #5 exhibits this transformation because I took the point (0,1) and shifted it up 4 units to get (0,5). Graph #5 is the only graph that showed point (0,5).

h(x) = f(x + 4) → Graph #6

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the x-values of f(x) by -4.

⭐ Graph #6 exhibits this transformation because I took point (0,1) and shifted it left 4 units to get (-4,1). Graph #6 is the only graph that showed point (-4,1).

k(x) = f(x) - 4 → Graph #4

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) down by 4.

⭐ Graph #4 exhibits this transformation because I took point (0,1) and shifted it down 4 units to get (0,-3). Graph #4 is the only graph that showed point (0,-3)

m(x) = f(x - 4) → Graph #3

⭐ This transformation of f(x) means that to get to g(x), you have to shift all of the x-values of f(x) right by +4.

Answer:

i. (10-y)(100x^2 +10xy + y^2)

ii. See the explanation

Step-by-step explanation:

i. 1000x³-y³ =

10³x³ - y³ =

(10x)³ - y³ =  ==> use formula: x³ - y³ = (x-y)(x^2+yx+y^2)

(10-y)((10x)^2 +10xy + y^2) =

(10-y)(10^2 * x^2 +10xy + y^2) =  ==> simplify

(10-y)(100x^2 +10xy + y^2)

ii. 992/124=

When two lines are crossed by a transversal, a number of angle pairs are formed. The sum of the measures of these angle pairs can be used to solve for unknown angles in the diagram.

Here are some of the angle pair relationships that hold for two lines crossed by a transversal:

Using these relationships, you can set up equations to solve for unknown angles in the diagram. For example, if you are trying to find the measure of angle A, you might use the fact that corresponding angles are congruent to set up the equation "m<A = m<D". Then, you can use other angle pairs to find the measures of the other angles, and solve the system of equations to find the measure of angle A.

The number of CDs that can be bought are { 5, 4, 3, 2, 1 }.

What is an inequality ?

A relationship between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. So inequality emerges from an imbalance.

Given, No. of CDs = x

A CD costs $11 and He has total $60.

So, According to the question,

No. of CDs × Cost of each CD ≤ 60

                                         x × 11 ≤ 60

                                         11x ≤ 60

                                          x ≤ 60/11

Since the number of CDs can't be in fraction and The maximum CDs can be bought is 5.

So, The possible No. of CDs that can be purchased are { 5, 4, 3, 2, 1 }

The number of cans collected in the second week would be 225 cans.

A can of food is a container that holds a prepared food product, such as vegetables, fruits, beans, or soups. Canned foods are shelf-stable, meaning they can be stored for long periods of time without spoiling. They are often used as a convenient and easy-to-store source of food, especially in emergency situations.

To find out how many cans of food were collected in the second week, you need to subtract the number of cans collected in the first week from the total number of cans collected. In this case, the number of cans collected in the second week would be:

To compare two numbers, a, and b, we can write two inequalities:

a < b when a is less than b

a > b when a is greater than b.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We may write two inequalities to compare two numbers, a and b:

a < b

a > b

If a is less than b, then the first inequality is true and the second is false. If a is greater than b, then the first inequality is false and the second is true. Otherwise, if a and b are equal, then both inequalities are false.

We can determine which inequality is true by comparing the values of a and b and using the rules of inequality.

For example, if a=3 and b=5, then we can determine that a < b is true and a > b is false because 3 is less than 5.

On the other hand, if a=8 and b=2, then we can determine that a < b is false and a > b is true because 8 is greater than 2.

The division of the whole numbers is not closed under property as the division of whole number is not always a whole number.

A set has the closure property under a particular operation if the result of the operation is always an element in the set.  If a set has the closure property under a particular operation then we say that the set is “closed under the operation.” The closure property of the division tells that the result of the division of two whole numbers is not always a whole number. Whole numbers are not closed under division that is  a ÷ b is not always a whole number.

For example, 5 and 8 are whole numbers, but 5÷8 is not a whole number.

Therefore, closure property does not exist for division of whole numbers.

Ex. Because the zero point is set arbitrarily and does not indicate the complete absence of temperature, the Fahrenheit scale is an interval scale.

Zero degrees on either scale is not a "true" zero because it is an arbitrary number. The absence of temperature does not occur at the zero point; It's just a random number on the scale. Other examples of common interval scales include: Age and SAT scores (one is culturally determined).

⭐ Perpendicular lines have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to

The slope of the line the perpendicular like is perpendicular to is [tex]\frac{-1}{2}[/tex].

Therefore, the slope of the perpendicular line is [tex]2[/tex]

Substitute the slope into the point-slope form equation.

You should know that a hole occurs if there is a common term between the the numeration and the denominator when factorized, For vertical assumption, the denominator must be equal to zero and horizontal assumption, numerator will be equal to denominator

The given expression is:

The Hole is

Factorize the numerator= x²-2x

x is common in the expression

Factorize the denominator= x³-9x²-10x

x(x²-9x-10)

= [x²-10x+x-10]

x[(x²-10x)+(x-10)]

Simplify further to get

x[x(x-10)+1(x-10)]

=x[(x+1)(x-10)]

Combine numerator and denominator to see the hole

[tex]\frac{x(x-2)}{x(x+1)(x-10)}[/tex]

From the expression the hole is x

b. vertical assumption

The denominator =0

x³+9x²-10x=0
