Let us consider [tex]3x^{2}-13x+6[/tex] as equation→(1) of a Quadratic Equation assume some values for x which is satisfies the equation and doesn't satisfy equation by "hit and trail method".
x=1 substitute in the equation (1) we get ⇒ [tex]\frac{4}{3}[/tex]

8. Which is a solution of the equation y = 2x + 5? (1 point)
5,20
6,12
3,11
4,14.
I need this really quickly. Thanks to anyone willing to help.
Answer:
3,11
Step-by-step explanation:
Since y = 2x + 5, if you chose (x,y) (3,11):
11 = 2*3 + 5
11 = 6 + 5
11 = 11
Answer:
(3, 11 ) is a solution
Step-by-step explanation:
substitute the x- coordinate of the points into the equation and if the value of y obtained equals the y- coordinate then the point is a solution.
(5, 20 )
y = 2(5) + 5 = 10 + 5 = 15 ≠ 20 ← not a solution
(6, 12 )
y = 2(6) + 5 = 12 + 5 = 17 ≠ 12 ← not a solution
(3, 11 )
y = 2(3) + 5 = 6 + 5 = 11 ← solution
(4, 14 )
y = 2(4) + 5 = 8 + 5 = 13 ≠ 14 ← not a solution

The difference of given decimal numbers is (12.504, 12.495).
Given that, (13.4-0.896, 8.4+4.095).
What is the difference of two decimal numbers?Subtracting decimals:
1. Write down the two numbers, one under the other, with the decimal points lined up.
2. Add zeros so the numbers have the same length.
3. Then subtract normally, remembering to put the decimal point in the answer.
Here,
13.4-0.896 =12.504
8.4+4.095 =12.495
So, (13.4-0.896, 8.4+4.095) =(12.504, 12.495)
Hence, the difference of given decimal numbers is (12.504, 12.495).

Bill uses mirrors to augment the “laser experience” at a laser show. At one show he places three mirrors, A, B, C, in a right triangular form. If the distance between A and B is 20m more than the distance between A and C, and the distance between B and C is 20m less than the distance between A and C, what is the distance between mirror A and mirror C?
The distance between the mirrors A and C is 80 m.
What is Pythagoras theorem?The Pythagoras theorem tell the relation between the sides of a right triangle, in this we relate the hypotenuse to the other two sides of the triangle, mathematically expresses as- (hypotenuse)² = (Side1)²+(Side)²
Given that, Bill performed a show by placing three mirrors A, B and C in right triangular form, the distance between A and B is 20 m more than the distance between A and C, and the distance between B and C is 20 m less than the distance between A and C,
Let the distance between A and C be x,
AC = x
AB = x+20
BC = x-20
Using Pythagoras theorem,
AB² = AC²+BC²
x²+(x-20)² = (x+20)²
x²+x²+400-4x = x²+400+40x
x²-80x = 0
x(x-80) = 0
x = 0 or x = 80 (Neglecting x = 0 because distance between two sides of a triangle can't be 0)
Hence, The distance between the mirrors A and C is 80 m.

1/2
2/6
2/3
3/6
2/6 is the equivalent fraction for the fraction represented on the given number line. So, B is the correct option
What is an equivalent fraction ?
According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.
For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.
The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.
as 2/6 can further reduced to 1/3 which is represented on to the number line as 1/3 which is equal to 2/6

Operations on Algebraic Expressions: The three major components of an algebraic expression are variables, constants, and coefficients. Addition, subtraction, multiplication, and division are the four fundamental operations. We solve both difficult and straightforward equations using operations on algebraic expressions.There are three categories of algebraic expressions: monomial, binomial, and polynomial or multi-term expressions.These are the algebraic terms: Alphabetic letters alone or in combination with numbers or fractions are the variables.The numbers that are connected to the variables in a single term are called coefficients.Constants: Single integers or numbers that are typically connected to other terms through elementary operations.Examples include 8xyz, 25x+12y+9, 2yz23zy, and 3a+2b+5c.Algebraic Expression Types

remember, the inverse function of y = e^x is x = ln(y).
and the inverse function of y = ln(x) is x = e^y.
we want to find the value of x, where f(x) = 28.
28 = 0.48ln(x + 2) + 27
1 = 0.48ln(x + 2)
1/0.48 = ln(x + 2)
e^(1/0.48) = x + 2

of envelopes. How many packs of
envelopes would the store sell if it sold
15 packs of paper?
Answer:
If the local office supply store sells 5 packs of paper, it also sells 8 packs of envelopes. This means that the store sells 8 packs of envelopes for every 5 packs of paper.
If the store sells 15 packs of paper, it will sell 15 packs of paper * (8 packs of envelopes / 5 packs of paper) = <<15*(8/5)=24>>24 packs of envelopes.
Therefore, if the local office supply store sells 15 packs of paper, it will sell 24 packs of envelopes.

What is Mean?
A group of two or more numbers is simply averaged mathematically to get the term "mean." There are several ways to calculate the mean for a given collection of numbers, including as the arithmetic mean approach, which utilises the sum of the series' values, and the geometric mean method, which uses the average of a group of products. However, the majority of the time, the results from all of the main approaches to calculating a simple average are roughly the same.
There are two different types of means that can be calculated: the arithmetic mean and the geometric mean.
The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of numbers in the set.
Mean is the ratio of sum of observations to the total number of observation.

Answer:
[tex]\huge\boxed{\sf b = -3}[/tex]
Step-by-step explanation:
Given equation:-3(3 + 6b) = 36 - 3b
Distribute
-9 - 18b = 36 - 3b
Add 3b to both sides
-18b + 3b - 9 = 36
-15b - 9 = 36
Add 9 to both sides
-15b = 36 + 9
-15b = 45
Divide -15 to both sides
b = 45/(-15)
b = -3[tex]\rule[225]{225}{2}[/tex]
Answer:
The value of b is -3.
Step-by-step explanation:
The equation is,
→ -3(3 + 6b) = 36 - 3b
Now the value of b will be,
→ -3(3 + 6b) = 36 - 3b
→ -3(3) - 3(6b) = 36 - 3b
→ -9 - 18b = 36 - 3b
→ -18b + 3b = 36 + 9
→ -15b = 45
→ b = -(45/15)
→ [ b = -3 ]
Hence, the value of b is -3.

What is the system of linear equations in matrices?
A system of linear equations in matrices is a set of linear equations that can be expressed in matrix form. In this form, the equations are written as a matrix equation of the form Ax = b, where A is an m × n matrix of coefficients, x is an n × 1 matrix of variables, and b is an m × 1 matrix of constants. The solution to the system of equations can be found by solving for the matrix x using the matrix equation Ax = b. This can be done using various techniques, such as Gaussian elimination or matrix inversion. Matrix equations can be used to solve systems of linear equations for which the traditional algebraic methods are difficult or impossible.
We can prepare the equations as:
Equation 1: 6x - 4y = 3
Equation 2: 2x + 4y = -2
Hence, the equations of the system would be 6x - 4y = 3 and 2x + 4y = -2.

Step-by-step explanation:
1.) Expand the expression with distributive property. If we expand, we get 10x^2+6xy.
2.) Figure out m and n based on the expression. Since m is in front of the x^2, that means that m=10, and since n is in front of the xy, that means that n=6.
3.) Compute based on m and n. Since m is 10 and n is 6, m - n = 10 - 6 = 4. Therefore, D.) is the answer.
