Answer:
Obviously its x=3-23=-20.
Hi there! My name is Zalgo and I am here to help you out on this wonderful day. "23+x=3", it seems that we need to find the "X value". That would be "-20". In order to test that it is the correct answer, just input it into the equation. "23+-20=3".
I hope that this helps! :)

In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.
True
False
Answer:
The correct answer option for this is: False.
Step-by-step explanation:
We are given the following statement which we are to determine whether its true or false:
In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.
To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.
While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
The system of equations y = –2x + 1 and y = x + 5 is shown on the graph below.Which statement is true about the solution to the system of equations? The x-value is between –1 and –2, and the y-value is between 3 and 4. The x-value is between 3 and 4 , and the y-value is between –1 and –2. The x-value is between 1 and 2, and the y-value is between –3 and –4. The x-value is between –3 and –4, and the y-value is between 1 and 2.
Answer:
The x-value is between –1 and –2, and the y-value is between 3 and 4
Step-by-step explanation:
we have
y=-2x+1 ----> equation A
y=x+5 ----> equation B
Solve the system of equations by elimination
Multiply the equation B by 2 both sides
2y=2x+10 ----> equation C
Adds equation A and equation C
y=-2x+1
2y=2x+10
---------------
y+2y=1+10
3y=11
y=11/3
Find the value of x
y=x+5
11/3=x+5
x=(11/3)-5
x=-4/3
therefore
x=-1.33, y=3.67
The x-value is between –1 and –2, and the y-value is between 3 and 4
The x-value is between –1 and –2, and the y-value is between 3 and 4

The volume (V) of a pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] area of base × height, hence
V= [tex]\frac{1}{3}[/tex] × 64 × 8 ≈ 170.7 ( to 1 dec. place )
For this case we have that by definition, the volume of a pyramid is given by:

Where:
[tex]A_ {b}:[/tex] It is the area of the base
h: It's the height
According to the data we have:

An engineer on the ground is looking at the top of a building. The angle of elevation to the top of the building is 46°. The engineer knows the building is 250 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?
Answer:
=241 ft
Step-by-step explanation:
The building is opposite the angle of elevation. Thus using trigonometric ratios it is easier to use Tangent of the elevation angle to find the distance to the foot of the building (adjacent).
Tan ∅ = opposite/ adjacent
Tan ∅= height of the building/ distance between the engineer and the building
distance= height/tan ∅
=250/tan 46°
=241 ft
=
Answer: 241 feet.
Step-by-step explanation:
Observe the figure attached, where "x" is the distance from the engineer to the base of the building to the nearest whole foot.
We need to remember this identity:
[tex]tan\alpha=\frac{opposite}{adjacent}[/tex]
In this case we know that:
[tex]\alpha=46\°\\opposite=250\\adjace nt=x[/tex]
Therefore, the next step is to substitute these values into [tex]tan\alpha=\frac{opposite}{adjacent}[/tex]:
[tex]tan(46\°)=\frac{250}{x}[/tex]
And the final step is to solve for "x":
[tex]x*tan(46\°)=250\\\\x=\frac{250}{tan(46\°)}\\\\x=241ft[/tex]

Which values for A and B will create infinitely many solutions for this system of equations? ax-y=8 2x+y=b
Answer:
a = -2 , b = -8
Step-by-step explanation:
* Lets talk about the solution of the linear equations
- There are three types of the solutions of the system of linear equations
# If the two lines intersect each other, then there is one solution
- The equations are ax+ by = c , dx + ey = f
# If the two lines parallel to each other, then there is no solution
- The equations are ax+ by = c , ax + by = d in its simplest form ,
where a is the coefficient of x , b is the coefficient of y and
c , d are the numerical terms
# If the two lines coincide (over each other), then there are infinite
solutions
- The equations are ax+ by = c , ax + by = c in its simplest form, where
a is the coefficient of x , b is the coefficient of y and c is the
numerical term
* Lets solve the problem
∵ The system of equation is:
ax - y = 8 ⇒ (1)
2x + y = b ⇒ (2)
∵ The system create infinitely many solutions
∴ The lines are coincide
- The equations must be equal, then multiply equation(1) or (2) by -1 to
make the coefficient of y in the two equations equal
∴ -ax + y = -8
∴ 2x + y = b
∵ Their coefficients of x are equal
∵ Their coefficients of y are equal
∵ Their numerical terms are equal
∵ The coefficient of x in equation (1) is -a and in equation (2) is 2
∴ -a = 2 ⇒ multiply both sides by -1
∴ a = 2
∵ The numerical term in equation (1) is -8 and in equation (2) is b
∴ b = -8
* The values for a and b will create infinitely many solutions are -2 , -8
How many vertices are in the polyhedron?
Answer:
There are 20 vertices in the polyhedron.
The number of vertices in a polyhedron can be determined using Euler's formula or the specific properties of certain polyhedra such as platonic solids. The number of vertices varies depending on the type and structure of the polyhedron.
The number of vertices in a given polyhedron depends on the specific characteristics of the shape. According to the Euler's formula, represented as V - E + F = 2 (where V is the number of vertices, E the number of edges, and F the number of faces), we can determine the number of vertices if the other values are known.
For instance, a tetrahedron has 4 vertices, an octahedron has 6, a icosahedron has 12, a cube (also known as a regular hexahedron) has 8, and a dodecahedron has 20 vertices.

Two parallel lines are crossed by a transversal.
Answer:
Value of x is 37.
Step-by-step explanation:
Given:
line y and line z are parallel.
line x is traversal line.
To find: value of x.
∠( 3x + 4 )° and ∠ 115° are alternate interior angle in the given figure.
We know that Alternate interior angles of parallel lines are equal.
So,
3x + 4 = 115
3x = 115 - 4
3x = 111
x = 37
Therefore, Value of x is 37.
Two parallel lines are crossed by a transversal then the value of x is 37.
Given that line y and line z are parallel and line x is a traversal line.
To find that value of x.
We have ∠( 3x + 4 )° and ∠ 115° are alternate interior angles in the given figure.
We know that Alternate interior angles of parallel lines are equal So,
3x + 4 = 115
3x = 115 - 4

The probability that it is not red is 0.6.
What is Probability?It is the ratio of total favorable outcome to the total number of outcomes.The value of probability lies between 0 and 1.Given: A bag contains 10 marbles.
Number of red marbles = 4
Number of blue marbles = 3
Number of white marbles = 2
Number of yellow marble = 1
A marble is drawn at random.
We have to find the probability that the marble is not red.
Hence, the marble can be blue, white and yellow.
∴ Apart from red marbles there are total of 6 marbles in the bag.
⇒ Total favorable outcomes = 6
⇒ Total number of outcomes = 10
Probability = (Total number of favorable outcomes) / (Total number of outcomes)

Answer:
-4v + 2w = 7 is not a linear equation.
Step-by-step explanation:
A linear equation is one in the form:
y = mx + x
-4v + 2w = 7 is not a linear equation since it has v and w instead of y and x.
A linear equation is any equation in the form Ax + By = C, with the degree of each variable being 1 and the exponents strictly positive. Hence x^4 = y is not a linear equation because the exponent of x is 4.
Explanation:In mathematics, a linear equation is any equation that can be written in the form Ax + By = C, where A, B, and C are constants, and x and y are variables. The degree of each variable in all the terms should be 1 and the exponents of the variables should be strictly positive integers. For example, an equation like ‘2x + 3y = 5’ would be considered linear. Looking at the provided options:
–4v + 2w = 7 is a linear equation2x + 3y = 5 is also a linear equationx = -5 is a linear equationHowever, x^4 = y is not a linear equation because the exponent of x is 4, not 1.Therefore, the answer is x4 = y.
