Given:
The objective is to find the number.
Explanation:
Consider the unknown number as x,
First, four times the number can be written as 4x.
Twenty more than 4 time the number will be,
[tex]4x+20\ldots\ldots.\text{ (1)}[/tex]Then, twice the number can be represented as 2x.
And the difference between 2 and twice the number will be,
[tex]2-2x\ldots\ldots..(2)[/tex]Now, equate both the equations (1) and (2).
[tex]\begin{gathered} 4x+20=2-2x \\ 4x+2x=2-20 \\ 6x=-18 \\ x=\frac{-18}{6} \\ x=-3 \end{gathered}[/tex]Hence, the unknown number is -3.

Answer:ok
Step-by-step explanation: good job
The output of the program code block given will be two.
What is Python Programming language?Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation.
Given is the following code structure -
x = 6 % 2
if x == 1:
print("ONE")
else:
print("TWO")
If we dry run the program, we can write -
x = 6 % 2
x = 0
Now, x is not equal to 1, therefore, it will print two.
Therefore, the output of the program code block given above will be two.

2x + 8 = -4 I NEED ALL PLS
Answer:
Answer down below!
Step-by-step explanation:
Let's write out the equation!
2x + 8 = -4
To solve this, you have to subtract the 8 and bring it over to -4
That would look something like:
2x -(+8) = -4 -8
That leaves you with 2x = -12
Now you divide 2 and -12 which will give you
-6
Answer:X= - 6
Step-by-step explanation:
MOVE +8 to the right which would make it negative so -8-4.You would add both numbers which would be -12 and then u divide -12 with 2 so
-12/2 is -6

[tex]\begin{gathered} x_1=-8 \\ y_1=4 \\ x_2=-8 \\ y_2=-9 \end{gathered}[/tex]By substituting these values into the slope formula, we have
[tex]\begin{gathered} slope\text{ = }\frac{y_2-y_1}{x_2-x_1} \\ =\frac{-9-4}{-8-(-8)} \\ =\frac{-9-4}{-8+8} \\ =\frac{-13}{0} \\ \Rightarrow slope=\infty \end{gathered}[/tex]Hence, the slope of the line that passes through the points (-8, 4) and (-8. - 9) is evaluated to be

Answer: (y-(-43))=-7(x-6) and y=-7x-1
Step-by-step explanation:
1) Pick two points. I'll choose (3,-22) and (6,-43)
2) Next set it up in a rise-over-run function
-43 - (-22)
-------------
6 - 3
3) Solve
-21/3
-7
The slope is -7
4) Find the starting value.
You can do this by substituting two points in a slope-intercept equation(y=mx+b)
y=-7x+b
-22=-7(3)+b
-22= -21+b
-1=b
The starting value is -1.
5) Slope intercept form
We can put all the info together to find that the slope-intercept is:
y=-7x-1
6) Point-slope form:
Point slope form equation is this: y-y1=m(x-x1)
y1 and x1 are one of the points while keeping x and y as variables
So our final equation is (y-(-43))=-7(x-6)

The results of the operation of multiplication between two functions are, respectively:
2 · x³ + 12 · x² + 24 · x + 16 x⁴ + 4 · x³ - 16 · x - 16 - 32 2 · x³ + 12 · x² + 24 · x + 16 x⁴ + 4 · x³ - 16 · x - 16 2 · x³ - 4 · x² - 8 · x - 16 - 27How to find the product of two functions
According to function theory, there are five operations between two functions to create resulting functions:
Addition - f(x) + g(x) = (f + g) (x).Subtraction - f(x) - g(x) = (f - g) (x).Multiplication - f(x) · g(x) = (f · g) (x).Division - f(x) / g(x) = (f / g) (x).In this problem we must use the operation of multiplication between two functions.
Case 1
(f · g)(x) = (2 · x + 4) · (x² + 4 · x + 4)
(f · g)(x) = (2 · x + 4) · x² + 4 · (2 · x + 4) · x + 4 · (2 · x + 4)
(f · g)(x) = 2 · x³ + 4 · x² + 8 · x² + 16 · x + 8 · x + 16
(f · g)(x) = 2 · x³ + 12 · x² + 24 · x + 16
Case 2
(h · g)(x) = (x² - 4) · (x² + 4 · x + 4)
(h · g)(x) = (x² - 4) · x² + (x² - 4) · (4 · x) + (x² - 4) · 4
(h · g)(x) = x⁴ - 4 · x² + 4 · x³ - 16 · x + 4 · x² - 16
(h · g)(x) = x⁴ + 4 · x³ - 16 · x - 16
Case 3
(f · h)(x) = (2 · x + 4) · (x² - 4)
(f · h)(x) = 2 · x³ - 8 · x + 4 · x² - 16
(f · h)(x) = 2 · x³ - 4 · x² - 8 · x - 16
(f · h)(2) = 2 · 2³ - 4 · 2² - 8 · 2 - 16
(f · h)(2) = - 32
Case 4
(g · f)(x) = (x² + 4 · x + 4) · (2 · x + 4)
(g · f)(x) = 2 · x³ + 12 · x² + 24 · x + 16
Case 5
(g · h)(x) = (x² + 4 · x + 4) · (x² - 4)
(g · h)(x) = x⁴ + 4 · x³ - 16 · x - 16
Case 6
(f · h)(x) = (2 · x + 4) · (x² - 4)
(f · h)(x) = 2 · x³ - 4 · x² - 8 · x - 16
Case 7
(h · g)(x) = (x² - 4) · (x² + 4 · x + 4)
(h · g)(x) = x⁴ + 4 · x³ - 16 · x - 16

The variance of the sample mean is 12/35 = 0.3429.. This is a result of uniform distribution.
The uniform distribution is a continuous probability distribution and is concerned with events that are equally likely to occur. When working out problems that have a uniform distribution, be careful to note if the data is inclusive or exclusive.
According to the question, we have
Sample size (n) = 36; uniform continuous distribution has a maximum of 14 and a minimum of 2.
The notation for the uniform distribution is
X U(a,b), where a= the lowest value of x and b= the highest value of x. The probability density function is f(x) = 1/(ba ) fo axb .
b = 14 and a = 2.
Variance in uniform distribution = (b-a)² / 12.
Put the value of a and b,
Variance = ( 14-2)²/12 = 12
Sample variance is used to calculate the variability of sample sets.

The value of the Constant of Proportionality will be $2.19.
In the given question, it is stated that 3 pounds of grapes cost $6.57. We have to calculate and find out the Constant of Proportionality.
The constant of Proportionality is a constant term in the equation that does not vary and has a fixed value that represents a certain quantity in a given situation.
Here, we know that 3pounds cost $6.57. Taking:
y = Total Cost
x = Number of Pounds
c = Constant of Proportionality
We get the equation to represent the Total cost with respect to the number of pounds where c will be the proportionality constant which defines the unit price of a pound. The equation will be:
=> y = c*x
=> 6.57 = 3c
=> c = 2.19
Hence, we get the Constant of Proportionality $2.19

A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
We are given that radius of the cone as 5yd and slant height as 13yd
We first find the height using pythagoras theorem
Let height be h
by Pythagoras theorem we have
[tex]r^{2}+h^{2}=13^2\\ 5^2+h^2=169\\ h^2=144\\h=12[/tex]
Height of the cone is 12yds
Now volume of the cone is given by
[tex]V=[/tex]π[tex]r^{2}\frac{h}{3}[/tex]
Substituting the values in the equation we get

Dividing decimals by whole numbers !pls helpp divide 4./280.8
When dividing 4 by 280.8, the answer gotten is 0.014245.
What are decimals?It should be noted that decimal numbers are numbers that have whole numbers as well as fractional parts. One of the number types in algebra that has a whole integer and a fractional portion separated by a decimal point is a decimal. The decimal point is the dot that appears between the parts of a whole number and a fraction. An example of a decimal number is 34.5. Examples are 2.4 and 9.34.
To divide a decimal by a whole number, follow these steps.
Directly above the decimal point in the dividend, place the decimal point in the quotient.Divide using full numbers in the same way as you would.Divide until there is no remainder or until a pattern emerges in the quotient. Whenever necessary, annex zeros.In this case, Dividing 4 by 280.8 will give a value of 0.014245.
