In the expression 4x3 + 12, which is a coefficient, which is the variable, and which is a constant?

To find the sale price of the item, we need to multiply the regular price by the discount percentage, then subtract the result from the regular price. In this case, the discount is 45% * $85 = $<<45*.01*85=38.25>>38.25. So the sale price of the item is $85 - $38.25 = $<<85-38.25=46.75>>46.75. Answer: \boxed{46.75}.

Answer:

$46.75

Step-by-step explanation:

Original price: $85

Markdown: 45%

Price: 0.55(85)=$46.75

Sale Price: $46.75

The factors are (3x + 2)(x + 5).

Factorization or factoring is the process of breaking down an entity—such as a number, matrix, or polynomial—into a product of another entity—or factors—that, when multiplied together, give the original number, matrix, or other entity.

Given  3x² + 17x + 10

factors of equation is

In order to factorize this expression, we can split the Middle Term.

If we want to factorize an expression like a x² + b x + c using this method, we need to think of two numbers that are like:

n₁.n₂ = a.c = 3.10 = 30

and n₁ + n₂ = b = 17

3x² + 2x + 15x + 10

= x(3x + 2) + 5(3x + 2)

= (3x + 2)(x + 5)

Hence, the factors are (3x + 2)(x + 5).

The percentage of the company she owns after selling its specific parts is equivalent to 41.66%.

In mathematics →

Given is that an entrepreneur sells of 1/2 her company to one buyer and 1/6 to another buyer.

Assume that the amount of company left in percentage is equivalent to {R%}. Let the complete company be represented by 100%. The remaining percent of company after selling half of it can be written as -

100 - {1/2 x 100} = 100 - 50 = 50%.

The remaining percent of company after selling 1/6 of it can be written as -

{R%} = 50 - {1/6 x 50} = 50 - 8.34 = 41.66%

The mean for a given set of observations is 3.67.

The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. A data set's mean (average) is calculated by summing all of the numbers in the set and then dividing by the number of values in the set. When a data collection is arranged from least to largest, the median is the midway value. The mode is the number that appears the most frequently in a data collection.

According to the given statement the width of the walkway (x) is 8 feet.

Four of the sides of a square's two-dimensional form are equal in length. In a square, all four internal angles were right angles, and the opposing sides are parallel to one another. Real-world examples of square-shaped things include floor tiles, tea towels, hexagonal tiles, cheddar cheese, and so on.

Area of a Square = (side)(side)

Total area of the pool and walkway = 506 sq. ft

Length of the pool and walkway = 7 + 2x

Width of the pool and walkway = 6 + 2x

Thus, we will have the equation of the total area as:

(7 + 2x)(6 + 2x) = 506

4x² + 12x + 14x + 42 = 506

4x² + 26x + 42 = 506

4x² + 26x + 42 - 506 = 0

Kelly's estimate cannot be said to be reasonable because it falls below the range of acceptable number of sunglasses from the given amount in each box.

We are told that Kelly bought 4 boxes.

Now, we are told that each box had either 20, 25, or 30 pairs of sunglasses in it.

Thus;

Minimum number of sunglasses = 20 * 4 = 80 sunglasses

Maximum number of sunglasses = 30 * 4 = 120 sunglasses

If x changes to 10, it means that x is multiplied by a factor of (10/5) = 2. Therefore, y is multiplied by this same factor (2). As a result, 7*2=14

Transformations. Transform is the verb form of change. Therefore, to modify a geometric shape would entail to make certain changes to that shape.

Transforming something into another thing is referred to by the verbs transform, metamorphosis, transmute, convert, and transfigure. Transform suggests a significant shift in form, nature, or function. To completely and instantly modify something or someone so that they are considerably better or more beautiful is to transform them. When you move into a new home, quit your job, or become a parent, you are experiencing "change."

"Transition" refers to the process that takes place before to, during, and following the change event. We experience transition on a bodily, emotional, and psychological level, and we change as a result.

The equation be like;

y - f(a) / (x - a) = f'(a)

y = f'(a) (x - a) + f(a)

The end behavior of the graph will be that it increases without bound as x approaches positive infinity, and decreases without bound as x approaches negative infinity.

The end behavior of a graph is a description of how the graph behaves as the x-values approach either positive or negative infinity. If the highest degree of the function is odd and the leading coefficient is positive, then the end behavior will be that the graph increases without bound as x approaches positive infinity and decreases without bound as x approaches negative infinity. This can be explained by examining the degree of the function. Since the degree is odd, the highest degree of the function must be an odd power, such as x^3. When x is positive and increasing without bound, the value of the function will also be increasing without bound, since the exponent is positive. Similarly, when x is negative and decreasing without bound, the value of the function will also be decreasing without bound, since the exponent is negative.

Since a Pediatricians prescribe 7 milliliters (ml) of acetaminophen for every 35 pounds of a child's weight, we desire to find how many milliliters of acetaminophen will the doctor prescribe for Jocelyn, who weighs 55 pounds.

First, we need to find the number of milliliters of acetaminophen per pound of child, n

n = number of milliliters, L/mass of child, m

The required sets of range of the corresponding functions are illustrated in the below solution part.

The range of a function is the set of all possible output values of the function.

To find the range of a function, we need to evaluate the function at every point in its domain and find the set of all possible output values.

For example, we are given the function f(x) = x² - 2x and the domain (-5, -1, 0, 5, 7). To find the range of this function, we need to evaluate it at every point in its domain, which gives us the following values:

f(-5) = (-5)² - 2 × (-5) = 25 + 10 = 35

f(-1) = (-1)² - 2 × (-1) = 1 + 2 = 3

f(0) = (0)² - 2 × (0) = 0

f(5) = (5)² - 2 × (5) = 25 - 10 = 15

f(7) = (7)² - 2 × (7) = 49 - 14 = 35

The range of the function is therefore the set of all possible output values, which are 3, 0, 15, and 35. Therefore, the range of this function is {3, 0, 15, 35}.

We can use the same method to find the range of the other functions in the questions. The ranges of the other functions are:

6) f(x)=x²-2x & Domain= (-5, -1, 0, 5, 7)

Range: {-1, 3, 0, 15, 35}

7) f(x) = -3x+12) & Domain= (-9, -4, 4, 8, 11)

Range: {0, 15, 36, 39, 48}

8) f(x)=x²-(x/2) & Domain = {4, 8, 12, 30)

Range: {2, 30, 102, 942}

9) f(x)= |x-2x & Domain= (-5, -4,-3, 3, 5)

Range: {-4, -3, 0, 3, 4}

10) f(x) = (x²/2) + 30 & Domain = {-4, -2, 6, 8)

To solve a system of equations using substitution, you can start by solving one of the equations for one of the variables, such as x or y. For example, in this case, we can solve the first equation for x by subtracting y from both sides, like this:

[tex]-x - y = 1[/tex]
[tex]-x = 1 - y[/tex]

Now that we have an expression for x in terms of y, we can substitute that expression into the second equation to solve for y. When we do that, we get:

[tex]y = -(1 - y) + 4[/tex]
[tex]y = -1 + y + 4[/tex]

Now we can rearrange the terms on the right-hand side to make it easier to solve for y:

[tex]y = y + 4 - 1[/tex]

And when we combine the y terms on the left-hand side, we get:

[tex]2y = 3[/tex]

Finally, we can solve for y by dividing both sides by 2, like this:

[tex]y = 3 / 2[/tex]

Once we know the value of y, we can substitute it back into any of the original equations to solve for the other variable, x. In this case, if we substitute the value of y into the first equation, we get:

[tex]-x - y = 1[/tex]
[tex]-x - (3 / 2) = 1[/tex]

We can solve for x by rearranging the terms on the left-hand side and then dividing both sides by -1, like this:

[tex]-x = -1 + (3 / 2)[/tex]
[tex]x = (1 - 3) / 2[/tex]
Therefore, the solution to the system of equations is x = -1 and y = 3/2.

It's important to check your solution by substituting the values of x and y into the original equations to make sure they work. For example, if we substitute x = -1 and y = 3/2 into the first equation, we get:

[tex](-1) - (3 / 2) = 1[/tex]

And if we substitute the same values into the second equation, we get:

[tex](3 / 2) = (-1) + 4[/tex]

Both of these equations are true, which means our solution is correct.
