Answer: The equation that has the same solution as the given equation is −1 − 22 n = −20 n − 9. This can be seen by solving both equations for n.
To solve the given equation − 5 n + 31 = − 14 n − 5 for n, we can start by adding 5n to both sides to obtain 31 = − 9 n − 5. Then, we can add 9n and 5 to both sides to obtain n = −1.
To solve the equation −1 − 22 n = −20 n − 9 for n, we can start by adding 22n to both sides to obtain −1 = −20 n − 9. Then, we can add 20n and 9 to both sides to obtain n = −1.
Since both equations have the same solution for n (namely, n = −1), they have the same solution. Note that the other equations listed in the question do not have the same solution as the given equation. For example, the equation 1 = 0.75 n + 3.25 has the solution n = −4, while the equation 3 − 6 n + 3 n = − 3 + 4 − 4 n has the solution n = 1/5. These solutions are different from the solution n = −1 of the given equation, so these equations do not have the same solution as the given equation.

To derive the formula that goes through these two points, we use the general equation for an exponential equation.
Y = a(b)^x
There we will substitute the two points into this equation to get two equations
45 = a(b)^2
5/9= a(b)^-1
By dividing the first equation by the second, we obtain:
27 = b^3
Therefore b= 3
We plug b=3 into the first equation using the second point:
45 = a(3)^2
We get a = 5
Therefore the equation is y = 5(9)^x
We can verify this equation by plugging in the two points given to see if it works.
5/9 = 5(9)^-1
5/9 = 5/9
And:
45 =5(9)^2
45 = 45
It does, so the equation is correct.
The answer is y =5(9)^x

LMNO is a parallelogram. If NM\ =\ x+32\ and\ OL=2x+22,\NM = x+32 and OL=2x+22, find the value of x and then find NM and OL
Answer:
the value of x is 10
Step-by-step explanation:
Since LMNO is a parallelogram, the opposite sides are parallel and have the same length. This means that NO and LM have the same length, which we can call y. We can write the following equations to represent the given information:
NM = x + 32
OL = 2x + 22
NO = y
LM = y
Since NO and LM have the same length, we can set their lengths equal to each other to find the value of y:
x + 32 = y
2x + 22 = y
We can solve this system of equations by setting the two equations equal to each other and solving for x:
x + 32 = 2x + 22
-x = -10
x = 10
Substituting the value of x back into the equations for NM and OL, we find that:
NM = 10 + 32 = 42
OL = 2(10) + 22 = 32
Therefore, the value of x is 10, and the lengths of NM and OL are 42 and 32.

What is an equation?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.
|x+9|=|-x-9|
Both the sides have absolute symbols, consider as below:
x+9 = -x-9
=> 2x = -9 - 9 = -18
=> 2x = -18
=> x= -9
This means, x≤ -9 or x > -9
For graph:

Question 3
Evaluate g(x)=-3x+1, when x=10
Give a numerical answer.
Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 9200(1.018)²
Answer:
growth
1.8%
Step-by-step explanation:
If the number raised to the power x is between 0 and 1, it is decay since as the exponent increases, the value of the power expression decreases.
For example, think of 0.1, a number between 0 and 1.
0.1^x
x = 1, 0.1^1 = 0.1
x = 2, 0.1^2 = 0.01
x = 3, 0.1^3 = 0.001
As you see, as x increases, the value of the expression decreases from 0.1 to 0.01 to 0.001
Now look at a power in which the base is greater than 1.
If the number raised to the power x is greater than 1, it is growth since as the exponent increases, the value of the power expression increases.
For example, look at 1.5^x
1.5^x
x = 1, 1.5^1 = 1.5
x = 2, 1.5^2 = 2.25
x = 3, 1.5^3 = 3.375
As you see, as x increases, the value of the expression increases from 1.5 to 2.25 to 3.375.
Now our problem:
y = 9200(1.018)^x
What base is raised to x?
Answer: 1.018
Since 1.018 is greater than 1, as the exponent, x, increases, the value of 1.018^x increases. Therefore, this is exponential growth.
1.018 = 1 + 0.018 = 1 + 1.8%

After solving the equation, the value obtained for m ∠B will be equal to 132°.
What is an angle?An angle results from the intersection of two lines at a point. The term "angle" describes the width of the "gap" that exists between these two rays. It's represented by the symbol.
Angles are most frequently measured in degrees and radians, a measurement of roundness or rotation. Angles are a part of everyday existence.
As per the given information in the question,
The inside angle plus the external angle add up to 180°.
So,
m ∠B = (14x − 22)°
14x - 22° + 6x - 18° = 180°
14x + 6x - 22° - 18° = 180°
20x - 40° = 180°
20x = 180° + 40°
20x = 220°
x = 220° / 20
x = 11°
Now, let's find m∠B.
m ∠B = (14x − 22)°

One way to measure the amount of energy that a moving object (such as a car) possesses is by finding its Kinetic Energy. The Kinetic Energy (Ex, measured in Joules) of an object depends on the object's mass (m, 2Ek measured in kg) and velocity (v, measured in meters per second), and can be written as v = . m What is the kinetic Energy of an object with a mass of 1,700 kilograms that is traveling at 50 meters per second? Ek Joules The volume of a cone of sand moved by harvester ants given it's radius can be found with the following 3V formular = A mound of gravel is in the shape of a cone with the height equal to twice the radius. 2л Calculate the volume of such a mound of gravel whose radius is 4.92 ft. Use = 3.14. V = (round to the nearest whole number)
The body has a kinetic energy of 2125000 joules, and the gravel mold has a volume of 11.9 cubic units.
Given that,
The Kinetic Energy of an object depends on the object's and velocity , and can be written as v = m
Kinetic Energy of an object with a mass = 1,700 kilograms
Traveling = 50 meters per second
Radius = 4.92 ft
Kinetic energy, which may be seen in the movement of an item or subatomic particle, is the energy of motion. Kinetic energy is present in every particle and moving object. Examples of kinetic energy in action include a person walking, a baseball soaring through the air, a piece of food falling from a table, and a charged particle in an electric field.
Kinetic Energy of a body is given by ,
1/2 mv²
Where m = mass = 1700 kg
v = velocity = 50m/s
Therefore ,
KE = 1/2 * 1700kg * 50m/s
KE = 2125000 J.
Now to calculate the volume
Let's assume that the solution to the problem will be found using your formula. If so, let's carry out the following operations when solving for v in the equation:
On multiplying the equation by 2, the outcome is
2[tex]r^{2}[/tex]
=3[tex]\sqrt{3V}[/tex]
To find volume
enter (v=(2[tex]r^{2}[/tex])/33)
rationalize the right side of the equation's numerator.
v=(2π[tex]r^{2}[/tex] )
A simplified version of 3/333 is
v=(2[tex]r^{2}[/tex])3/9.
Substitute
v=(23.143.1523)/9
v=11.9.
Therefore,
The body has a kinetic energy of 2125000 joules, and the gravel mold has a volume of 11.9 cubic units.

What is the quotient of
102 and 5?
The leftover after dividing 102 by 5 is the quotient, which is:
Quotient 20
Remainder 2
102 5: Quotient and Remainder
The quotient and remainder method is one way to determine the quotient and remainder of a division. The dividend (102) and the divisor are already known to us (5). Now, we need to determine the residual and the quotient:
The Quotient and Remainder procedure is as follows:
20 quotient, 5 | 102 dividend, -10 2, and a reminder
As can be seen:
The remainder is 2, while the quotient is 20.
Sometimes, the remaining part is referred to as the "modulo," or simply "mod." This notation is used to say that:
102 mod 5 = 2

A ball is dropped from a height of 80 ft. The elasticity of this ball is such that it rebounds three-fourths of the distance it has fallen. How high does the ball rebound on the fifth bounce? Find a formula for how high the ball rebounds on the nth bounce.
Formula for how high the ball rebounds on the nth bounce is 80 (3/4)ⁿ ft and the rebound on 5th bounce is 14.24 ft.
It is given that the ball is dropped from 80 ft and it rebounds (3/4)th of the height it has fallen.
Firstly , using logic ,
The height reached by the ball on its 1st rebound = 80(3/4) = 60 ft
Similarly , calculating on it's 2nd rebound = 60(3/4) = 45 ft
and on 3rd rebound = 45(3/4) ft.
This forms a sequence , known as GP (Geometric Progression).
A Geometric Progression in mathematics, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Hence , here the first term : a = 60 ft
and common ratio is : r = 3/4
the general term for rebound on nth bounce
= 60 * (3/4)ⁿ⁻¹ = 80 (3/4)ⁿ ft
Using the above expression , the rebound on 5th bounce = 60 * (3/4)⁵ = 14.24 ft.
