Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. Hint: use addition property of equality and multiplication property of equality in your answers 5x + 2y = 7 3x - y = 2 A. To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations B. Why is this multiplication allowed? C. What variable will be eliminated when the equations are combined after the multiplication? D. Next, add the equations together. Your answer should be a single equation with one variable. E. Why can you add the equations? F. Solve the equation for x. G. Substitute x back into one of the equations to solve for y. H. What is the solution to the system of equations?
Answer:
Explained below.
Step-by-step explanation:
The system of two equations is:
[tex]5x+2y=7...(i)\\\\3x-y=2...(ii)[/tex]
Step A:
To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations.
[tex]5x+2y=7\\\\6x-2y=4[/tex]
Step B:
The multiplication is performed to simplify the elimination process.
Step C:
The variable that will be eliminated when the equations are combined after the multiplication is y.
Step D:
Next, add the equations together. Your answer should be a single equation with one variable.
[tex]5x+2y=7\\ +\\6x-2y=4\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\\\11x=11[/tex]
Step E:
We can add the equation because both the equation are in the same format, i.e. ax + by = c.
Step F:
Solve the equation for x.
11x = 11
x = 1
Step G:
Substitute x back into one of the equations to solve for y.
[tex]5x+2y=7\\\\(5\times 1)+2y=7\\\\5+2y=7\\\\2y=7-5\\\\2y=2\\\\y=1[/tex]
Step H:
The solution to the system of equations is: (x, y) = (1, 1).

Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1?
O f(x) = (x – 21)(x - 31)
O f(x) = (x +21)(x + 31)
f(x) = (x-2)(x - 3)(x - 21(x-31)
f(x) = (x + 21)(x + 3/)(x - 2)(x - 31)
Answer:
D. f(x)= (x+2i) (x+3i) (x-2i) (x-3i)
Step-by-step explanation:
Correct on edge 2020
The polynomial with a leading coefficient of 1 and roots 2i and 3i with multiplicity 1 is
f(x) = (x – 2i)(x - 3i)
Option A is the correct answer.
What is a polynomial?Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
We have,
f(x) = (x - 2i)(x - 3i)
It has two roots of 2i and 3i with multiplicity 1.
x² - 3ix - 2ix - 6
x² - 5ix - 6
The leading coefficient is 1.
Thus,
f(x) = (x – 2i)(x - 3i) has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1.

Angle x is (2n + 12) and angle y is (3n + 18). Find the measure of angle x.
Answer: X and Y are supplementary angles. The sum of the supplementary angles is 180.
So, X + Y = 180
180 = 2n+12 + 3n + 18
180 = 5n + 30
5n = 150
n = 30
X = 2n+12
X = 2(30) + 12
X = 72
Y = 3n + 18
Y = 3(30) + 18
Y = 108

Why does the efficient market hypothesis reduce the demand for financial advisors?
Part of a financial advisor's job is to allocate money in the best available asset or security (eg: stocks and bonds). So they look at market data and use mathematical models to help judge on where to put money. Their goal is to so called "beat the market", meaning they want to earn the best return compared to other players in the market. Doing so will allow them to "buy low, sell high" which is a common cliche in finance. Though it's a very good rule to follow of course.
The efficient market hypothesis says that whatever the stock price is currently, it reflects everything about that company. In other words, there are no hidden facts that may surprise investors to drastically change the price of the stock. All information is completely transparent. What this means is that anyone can determine where to put their money without the need for a financial advisor.
I don't think demand would be completely wiped out since even if in a 100% transparent environment, people would still prefer to have others manage their money or not want to deal with complicated math formulas. However, demand would be reduced to some degree. In reality, there are always hidden factors that don't fully contribute to the cost of a security, which is why the efficient market hypothesis isn't fully applicable in every situation. So this is likely why financial advisors are in demand and are paid well.

Find the area of a compound shape
Can you please explain
Answer:
[tex]A=292.53~m^2[/tex]
Step-by-step explanation:
Area of a Compound Shape
The shape shown in the image is made of two shapes: Half a circle of radius 8 m and a triangle of base 24 m and height 16 m.
The area of a circle of radius r is:
[tex]A_c = \pi r^2[/tex]
The area of a triangle of base b and height h is:
[tex]\displaystyle A_t=\frac{b.h}{2}[/tex]
Calculate the area of the circle:
[tex]A_c = \pi 8^2[/tex]
[tex]A_c = 64\pi[/tex]
Area of half the circle:
[tex]A_c/2 = 32\pi~m^2[/tex]
Area of the triangle:
[tex]\displaystyle A_t=\frac{24\cdot 16}{2}[/tex]
[tex]A_t=192~m^2[/tex]
The area of the shaded shape is:
[tex]A=32\pi~m^2+192~m^2[/tex]
Substituting the value of pi:
[tex]\mathbf{A=292.53~m^2}[/tex]
