Answer:

Step-by-step explanation:

You want the solutions to the rational equation ...

  [tex]\dfrac{2}{2x-6}-\dfrac{x}{x^2-9}=\dfrac{3}{x-3}[/tex]

We choose to rewrite the equation in the form f(x) = 0. We can start by subtracting the term on the right side (from both sides).

  [tex]\dfrac{2}{2x-6}-\dfrac{x}{x^2-9}-\dfrac{3}{x-3}=0\\\\\dfrac{2}{2(x-3)}-\dfrac{x}{(x-3)(x+3)}-\dfrac{3}{x-3}=0\\\\\\\dfrac{(x+3)-x-3(x+3)}{(x-3)(x+3)}=0\qquad\text{cancel 2 in first term; common denominator}\\\\\\\dfrac{-3x-6}{(x-3)(x+3)}=0\qquad\text{collect terms}[/tex]

The "not-possible values" will be values of x that make the denominator zero: x = ±3. The solution is ...

  [tex]-3(x+2)=0\qquad\text{numerator must be zero}\\\\\boxed{x=-2}\qquad\text{divide by -3, subtract 2}[/tex]

In the original equation, we have ...

  [tex]\dfrac{2}{2(-2)-6}-\dfrac{-2}{(-2)^2-9}=\dfrac{3}{(-2)-3}\\\\\dfrac{2}{-10}-\dfrac{-2}{-5}=\dfrac{3}{-5}\\\\-\dfrac{1}{5}-\dfrac{2}{5}=-\dfrac{3}{5}\qquad\text{TRUE}[/tex]

Additional comment

We like to write the equation as a single fraction compared to zero so that any common factors can be cancelled from numerator and denominator. This helps prevent extraneous solutions. Here, there are none.

The ordered pair (1, 12) lies on the graph of the exponential function f(x) = 3(2)2x. which is the correct answer would be option (A).

The graph of an exponential function of the form f(x) = abˣ is a curve that passes through the point (0, a), where a is the initial value of the function.

In the given equation, the initial value is 3, so the graph of f(x) passes through the point (0, 3).

To find other points on the graph of f(x), we can plug different values of x into the equation and solve for the corresponding value of y.

For example, if we plug x = 3 into the equation, we get:

f(3) = 3(2)² × 3

= 3(16)

= 48

Therefore, point (3, 48) does not lie on the graph of f(x).

Similarly, if we plug x = 1 into the equation, we get:

f(1) = 3(2)² × 1

= 3(4)

= 12

Thus, point (1, 12) lies on the graph of f(x).

The net pay of Billy after 8% taxes and 10% retirement policy is $1600.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, From Billy's salary of $2000 8% of his paycheck goes to income taxes, and 10% automatically goes into retirement.

So, To obtain a net salary of Billy we'll subtract the percentage amount of 8% and 10% from the base of $2000.

Therefore, Net pay of Billy is {2000 - (8/100)×2000 - (10/100)×2000}.

= {2000 - 160 - 200}.

= (2000 - 360).

Using a system of equations to solve the problem, the candy distributor must mix 190 Kilograms of the 20% chocolate and 10 Kilograms of the 60% chocolate to create 200 Kilograms of a 22% fat-content chocolate.

A system of equations means two or more equations solved simultaneously.

They are known as simultaneous equations and can be solved graphically, by elimination, by substitution, or matrix.

The fat-content of one of the chocolate blend = 20%

The fat-content of the second chocolate blend = 60%

The expected mixture will have a fat-content = 22%

The total kilograms of the end mixture = 200 kilograms

Let the 20% fat-content chocolate = x

Let the 60% fat-content chocolate = y

x + y = 200 ... Equation 1

Solving for x, x = 200 - y

0.2x + 0.6y = 0.22(200)  ... Equation 2

By substitution in Equation 2:

0.2(200 - y) + 0.6y = 44

40 - 0.2y + 0.6y = 44

40 + 0.4y = 44

0.4y = 4

y = 10

x = 200 - y

x = 190 (200 - 10)

Based on the system of equations, 190 kilograms of the 20%-fat-content chocolate must be mixed with 10 kilograms of the 60% fat-content chocolate.

After solving the equation for x, the resultant answer is (3, -2).

The definition of an equation in algebra is a mathematical statement that shows the equivalence of two mathematical expressions.

For example, the equation 3x + 5 = 14 comprises the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, we have the equation:

y = -2x +4

Now, get value of x for y = -2 as follows:

Fill in the equation with the value of y and find x:

-2 = -2x +4 . . . . use -2 for y

-6 = -2x . . . . . . . subtract 4

3 = x . . . . . . . . . .divide by -2

The given triangle is right triangle

The ratio of the given triangle angles = 45-45-90 degrees

To find the length of the sides we have to use the trigonometric functions

sin θ = Opposite side / hypotenuse

cos θ = Adjacent side / hypotenuse

tan θ = Opposite side / adjacent side

Find the value of x

sin 45 = Opposite side / 13[tex]\sqrt{2}[/tex]

Opposite side = 13[tex]\sqrt{2}[/tex] × sin 45

= 13 units

Similarly

cos 45 = Adjacent side / 13[tex]\sqrt{2}[/tex]

Adjacent side =  13[tex]\sqrt{2}[/tex] × cos 45

The four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e : ( 2, 3 ) , ( 2, 5 ) , ( 2, 7 ).

What is Function?

Function is a relation which each member of the domain is mapped onto exactly one member of the codomain.

There are many types of functions in mathematics such as :

Linear Function → f(x) = ax + b

Quadratic Function → f(x) = ax² + bx + c

Trigonometric Function → f(x) = sin x or f(x) = cos x or f(x) = tan x

Logarithmic function → f(x) = ln x

Polynomial function → f(x) = axⁿ + bxⁿ⁻¹ + ...

If function f : x → y , then inverse function f⁻¹ : y → x

Let us now tackle the problem!

According to the definition above, it can be concluded that a function cannot have the same x value.

Of the four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e :

Answer:

The answer is p = -6/3. This is the value of p that makes the original equation true.

Step-by-step explanation:

To solve this equation, we must first isolate the variable p on one side of the equation. To do this, we can use the properties of equality to add or subtract the same value from both sides of the equation.

First, we can subtract 2p from both sides of the equation to get rid of the 2p term on the left side. This gives us 0 = -3p - 6/4.

Next, we can add 6/4 to both sides of the equation to get rid of the constant term on the right side. This gives us 6/4 = -3p.

Finally, we can multiply both sides of the equation by -4/3 to get rid of the coefficient -3 on the right side. This gives us -6/3 = p.

Therefore, the value of p that makes the equation true is p = -6/3.

Math Illustrations enables you to produce more useful geometry figures for your students in less time by fusing the constraint-based design of Geometry Expressions with simple-to-use sketching and graphing features.

The number of cannonballs in the first layer = 1² = 1

Number of cannonballs in the second layer = 2² = 4

Number of cannonballs in the third layer = 3² = 9

So, the generalized formula to count the balls is given as

= n(n + 1) (2n + 1)/ 6

Here, n= the total number of layers

Put n =11

The most common kind of critical hit simply deals additional damage, most commonly dealing double the normal damage that would have been dealt, but many other formulas exist as well (such as ignoring defense of the target or always awarding the maximum possible damage).

A critical hit has the base damage x multiplied, next the damage reduction is applied to the critical hit. Bonus damage is not subject to damage reduction or critical hits, so this is applied last.

Here, Critical hit × Bonus × Damage reduction

That is, (c·r·b)(x) or (r·c·b)(x)
