Answer:
x=4
y= 5
Step-by-step explanation:
6x+y=29
3x-y=7
Let's add them together
9x = 36
x= 4
Then put 4 back in the equation for x
6(4) + y =29

A sum of money is to be divided between Alyah, Byron and Cecil. Alyah receives $1 plus one-third of what is left. Byron then receives $6 plus one-third of what remains. Cecil receives the rest, which amounts to $40. How much did Byron receive? (A) $26 (B) $28 (C) $30 (D) $32 (E) $34
Answer:
(A) $26
Step-by-step explanation:
You want to know the amount Byron received from the distribution to Alyah, Byron, and Cecil, given Cecil received $40.
SetupLet x represent the amount being distributed, and a, b, c represent the amounts received by Alyah, Byron, and Cecil, respectively.
The given relations tell us ...
a = 1 + 1/3(x -1)
b = 6 + 1/3(x -a -6)
c = x -a -b = 40
SolutionSubstituting for b gives us ...
40 = x - a - (6 +1/3(x -a -6)) = x -a -6 -1/3x +1/3a +2 = 2/3x -2/3a -4
44 = 2/3(x -a) . . . . . . . add 4, factor out 2/3
66 = x -a . . . . . . . . . multiply by 3/2
Substituting for a gives us ...
66 = x -(1 +1/3(x -1)) = x -1 -1/3x +1/3 = 2/3x -2/3 = 2/3(x -1)
99 = x -1 . . . . . . . multiply by 3/2
100 = x . . . . . . add 1
DistributionThen ...
a = 1 + 1/3(100 -1) = 1 + 99/3 = 34
b = 6 + 1/3(100 -34 -6) = 6 + 1/3(60) = 26
Byron received $26.
__
Additional comment
Based on results, the "what is left" is the amount after the $1 or $6 distributions are made.
Alyah: $34, Byron: $26, Cecil: $40, for a total of $100.

What is the value of 4 3 answer?
The value of 4 to the 3rd power =64
According to the power rule of exponents,
am = m times a x a x a
Thus, 43 can be written as 4 × 4 × 4 = 64.
Thus, the value of 4 to the 3rd power i.e., 4^3 is 64
Exponent is the process of representing huge numbers as powers, according to the definition. Exponent, then, is the number of times a number has been multiplied by itself. Using 6 as an example, multiply it by itself four times, or 6 6 6 6. You can write this as 64. In this case, the exponent is 4 and the base is 6.

How do you solve an equation with 5 variables?
A linear equation, with five variables, has an infinite number of solutions.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Let linear equation:
5 = x + a + b + c + y
In this equation,
there are five variables, x, a, b, c and y.
And the number of equation is one.
That means,
the number of unknowns > the number of equation
5>1.
Substitute the value of 4 variables to find the value of one variable.
Let, we have to find solutions as subject to y.
We so obtain varied values of y when preserving distinct values of x, a, b, c.
Therefore, infinitely many solutions are possible.

What us the third step in sketching the graph of a rational function
The third step in sketching the graph of a rational function is "Finding the function's zeros and vertical asymptotes and plotting them on a number line".
What is vertical asymptotes?
A graph's vertical asymptote is a vertical line with the equation x = a, where the graph tends to positive or negative infinity as the inputs get closer to the value of a. A graph's horizontal asymptote is a horizontal line with the equation y = b, where the graph approaches the line as the inputs go closer to ∞ or –∞.
The steps to sketch a graph of rational function:
1. Ensure that the function's denominator and numerator are listed in decreasing order of power.
2. Discover the domain
3. Completely factor the numerator and denominator. Any shared factors between the numerator and denominator should be eliminated. (Once factors have been cancelled, the reduced function is what remains. For all subsequent actions, employ the reduced function.) Skip Step 4 if there are no common factors.
4. Look for any holes
5. Search for any vertical asymptotes.
6. Find the Horizontal Asymptote.
7. Look for any x- and y-intercepts.
8. Locate test points

All the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x - 12 are 3/4 and -4/5.
We have the given polynomial:
f(x) = 20x4 + x3 + 8x2 + x - 12
All potential polynomial roots are represented by rational numbers, according to the Rational Root Theorem:
x = a/b
Where a is a factor of a constant term
b is the factor of coefficient of leading term
From the given polynomial:
-12 is the constant term and 20 is the coefficient of leading term
The possible factors of -12 are ±1, ±2, ±3, ±4, ±6, ±12
The possible factors of 20 are ±1, ±2, ±4, ±5, ±10, ±20
So the rational roots = (±1, ±2, ±3, ±4, ±6, ±12)/ (±1, ±2, ±4, ±5, ±10, ±20)
Solve for x when the given function is equal to zero
20x4 + x3 + 8x2 + x - 12 = 0
(4x - 3)(5x + 4)(x2 + 1) = 0
So we get:

We are aware that a discrete function is one that satisfies the criteria for a function and has a countable domain (represented as a collection of disconnected points) (each input has at most one output). Many inputs in discrete functions won't have any outputs.
According to the inquiry,
All three of the functions have a y-intercept and, given the facts in the question, f(x) is the highest maximum.

When there are exactly even numbers of observations in a data collection, the median can be calculated as follows:
sorting of the sample data in ascending or descending order.
If there are an even number of observations (let's say n), identify the (n/2)nd and [(n/2) + 1] th observations.
The average of the top two observations is the same as the median of the data given (as determined in step 2).

If you have three side lengths, you should find the angle opposite the smallest side to determine the lowest angle, the angle opposite the medium-sized side to determine the greatest angle, and the angle opposite the largest side to determine the greatest angle.
What are angles?Two rays that have a common terminal and are referred to as the angle's sides and vertices, respectively, make up an angle in Euclidean geometry. Two rays can form angles in the plane where they are positioned.
Angles are also produced when two planes intersect.
These are what are known as dihedral angles.
Consequently, if you have three side lengths, you should discover the lowest angle by finding the angle that is opposite the smallest side, the medium-sized angle by finding the angle that is opposite the medium-sized side, and the greatest angle by finding the angle that is opposite the largest side.

In 2010, the population of a city was 193,000. From 2010 to 2015, the population grew by 6%. From 2015 to 2020, it fell by 3%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answer:
6138
Step-by-step explanation:
First, we have to find the population of the city in 2015
6% = 0.06
193,000 times 0.06 = 11580 people increase
We know it is increasing, so we have to add them
193,000 + 11580 = 204580 people in 2015
Now let's find the 3% decrease
3% = 0.03
204580 times 0.03 = 6137.4
