Subtracting fractions with unlike denominators

Answer:

The 3x+1 problem, also known as the Collatz conjecture, is a problem in mathematics that remains unsolved. It involves taking a positive integer and repeatedly applying a simple rule to it: if the integer is even, divide it by 2, and if it is odd, multiply it by 3 and add 1. The problem is to determine whether this process will always eventually reach the number 1, regardless of which positive integer is chosen as the starting point. Despite much effort by mathematicians, the 3x+1 problem remains unsolved.

Step-by-step explanation:

The two solutions to the equation x² + 5x + 6 = 0 are x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

To find the roots of a quadratic equation, we need to set the equation equal to 0 and then solve for x. In this case, we have the equation x² + 5x + 6 = 0. we can use the quadratic formula. The quadratic formula states that the two solutions for x are given by x = (-b ± √(b² - 4ac))/2a. For our equation, this gives us x = (-5 ± √(5² - 4(1)(6)))/2(1). Once we simplify this, we get x = (-5 ± √(-19))/2. Since the square root of a negative number is not real, we can discard this solution. This leaves us with x = -2 and x = 3. This means that when we substitute either of these values into the equation, the left-hand side of the equation will be equal to 0.

x = (-5 ± √(5² - 4(1)(6)))/2(1)

= (-5 ± √(-19))/2

= (-5 ± i√19)/2

The number of student tickets sold is 40 and the number of adult tickets sold is 60.

Define System of equations

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given,

Each student ticket sells for = $4

Each adult ticket sells for = $8

Total tickets sale = 100

Revenue from the sale of 100 tickets = $640

Let, x = number of student tickets sold

and, y = number of adult tickets sold

so, let's form a equation

x + y = 100             ------(i)

4x + 8y = 640        -------(ii)

Rewrite eq(i),

x = 100 - y

Now, substitute x value in eq(ii)

4(100- y) + 8y = 640

400 - 4y + 8y = 640

4y = 640 - 400

y = 240 / 4

y = 60

Now, put y value in eq(i)

x + 60 = 100

x = 40

Hence, the number of student tickets sold is 40 and the number of adult tickets sold is 60.

Now, to solve graphically

Let's rewrite the eq(i) and eq(ii)

y = 100 - x

y = 80 - (1/2) x

Plot these lines on graph as mentioned below.

And, the solution is the point of intersection(40,60)

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

Answer:

1:1

Step-by-step explanation:

Since the surface area of A is 4 times the surface area of B, and the volume of B is 125 times the volume of C, we can write the following proportion:

(surface area of A) / (surface area of B) = (volume of B) / (volume of C)

(height of A)^2 / (height of B)^2 = (height of B)^3 / (height of C)^3

We can then cross-multiply and simplify to find the ratio of the heights:

(height of A)^2 / (height of C)^2 = (height of B)^3 / (height of B)^3

(height of A)^2 = (height of C)^2

Therefore, the ratio of the height of A to the height of C is 1:1, or simply 1.

What is judicial activism?

Judicial activism is a judicial philosophy that is sometimes referred to as "legislating from the bench". It is an exercise of judicial review and generally refers to the willingness of a judge to strike down legislative or executive actions regarding constitutional issues. Judicial restraint is generally thought of as the opposite of judicial activism.[1]

Earlier in the january of 1947 ,Arthur Schlesinger Jr. introduced the term "judicial activism" .An article by Keenan Kmiec says that in its early usage, it was sometimes used with a positive connotation akin to the term "civil rights activist".

A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

14 - 4[tex]\sqrt{6}[/tex] = ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])

14 - 4[tex]\sqrt{6}[/tex] = [tex]\sqrt{x}[/tex]([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex]) - 2[tex]\sqrt{y}[/tex]([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex])  ==> distribute ([tex]\sqrt{x}[/tex] - 2[tex]\sqrt{y}[/tex]) to [tex]\sqrt{x}[/tex] and

14 - 4[tex]\sqrt{6}[/tex] = (x) - (2[tex]\sqrt{xy}[/tex]) - (2[tex]\sqrt{xy}[/tex]) - (-4[tex]\sqrt{y}[/tex] *[tex]\sqrt{y}[/tex]) ==> simplify

14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) - (-4y)

14 - 4[tex]\sqrt{6}[/tex] = (x) - (4[tex]\sqrt{xy}[/tex]) + 4y  ==> subtracting by a negative number is

                                               equivalent to adding by a positive number

14 - 4[tex]\sqrt{6}[/tex] = x + 4y - 4[tex]\sqrt{xy}[/tex]   ==> notice any similarities?

x + 4y = 14

[tex]\sqrt{xy}[/tex] =  [tex]\sqrt{6}[/tex]

xy=6  ==> solve for x

x = 6/y  ==> isolate x by dividing by y on both sides

6/y + 4y = 14  ==> plugin 6/y for x in x + 4y = 14

(6/y + 4y = 14) * y  ==> multiply the equation by y to remove fractions

6 + 4y^2 = 14y

4y^2 - 14y + 6 = 14y-14y

4y^2 - 14y + 6 = 0

2y^2 - 7y + 3 = 0  ==> divide both sides by 2 to simplify the equation

2y^2 - 1y - 6y + 3 = 0  ==> -1y - 6y = -7y

y(2y - 1) - 3(2y - 1) = 0  ==> factor the equation

(y - 3)(2y - 1) = 0

y - 3 = 0 ==> y=3

2y - 1 = 0 ==> 2y = 1  ==> y = 1/2

y=3: 3x = 6 ==> plugin 3 for y in xy = 6

x = 2 ==> divide both sides by 3

y=1/2: x/2 = 6 ==> plugin 1/2 for y in xy = 6

x = 12  ==> multiply both sides by 2

When y=3, x=2.  When y=1/2, x=12

Hence, the answers are (2, 3) and (12, 1/2).

The expression will be simplified as x + 4y + 4√x√y -14 + 4√6 = 0.

Given the graph, the following values can be recorded:

Step-by-step explanation:

1. Multiply 1.5s x 3.5s = 5.25.

2) Because 1.5 has one s, and 3.5 has another s, these 2 s combine (s+s)=s^2. Meaning there is 2 s in the equation. s^2 happens when you multiply two numbers that each have an s. Multiplication in this problem is brought by the use of parenthesizes surrounding these 2 numbers.

The median of the data set would be affected as the median points per game decreases. That is option C.

The median of a data set is defined as the value of a data set the is found in the middle of a data after it has been arranged in an ascending order.
