a- A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2.
b- a financial gain, especially the difference between the amount earned and the amount spent in buying, operating, or producing something.
c- income, especially when of a company or organization and of a substantial nature.
d- (of an object or action) require the payment of (a specified sum of money) before it can be acquired or done.
e- The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form.
f- The substitution method is a way of solving a system of equations by expressing the equations in terms of only one variable.
g- The elimination method is where you actually eliminate one of the variables by adding the two equations.
h- Solving one particular problem without regard to related issues.
i- the point or state at which a person or company breaks even.
j- The domain of a function is the complete set of possible values of the independent variable.
k- The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.

The Gordon family plans to buy a TV. One TV has a purchase price of $330 and an estimated yearly operating cost of $14. The other has a purchase price of $369 and an estimated yearly operating cost of $9. Which TV should the Gordons buy if they plan to keep it for 8 years? Use rational functions to help justify your answer
Answers
Answer:
Step-by-step explanation:
They should purchase the $369 one with the $9 plan.
330 + (14x8) =442
369+ (9x8) = 441
Hope this helps!
Answer:
rational functions that model the average annual cost of each television if it is owned for x years, such as f(x)= (330+14x)/x and
g(x)= (369+9x)/x
calculation proving that over 8 years, the annual cost for the $330 television is $55.25; for the $369 television, it is $55.13
statement that the Gordons should buy the $369 television because it is less expensive overall

Answers
Answer:
the answer is (domain, range) or (x,y)
An ordered pair is written as, (domain, range). So Option A is correct
What is Domain and Range ?The domain of a function is the set of all input values (independent variable) for which the function is defined and produces a valid output (dependent variable).
The range of a function is the set of all possible output values of the function. It represents the set of all possible values of the dependent variable.
The set of all "x" values constitutes the domain, and the set of all "y" values constitutes the range, in a set of ordered pairs.
You should keep in mind that ordered pairs are represented by the following symbols: (x, y).
Find the domain when examining a collection of ordered pairs by compiling a list of all the relation's x values.

smallest sound intensity that can be heard by the human ear (roughly equal to 1x10-12 watts/m2).
Answers
Answer:
The intensity of sound in decibel is 65 dB
The intensity of sound in Watts/m² is 1 x 10⁻⁴ W/m²
Step-by-step explanation:
The intensity of sound in decibel is given by;
[tex]\beta (dB) = 10Log(\frac{I}{I_o})\\\\[/tex]
where;
I₀ is the smallest sound intensity that can be heard by the human ear = 1 x 10⁻¹² watts/m²
[tex]\beta (dB) = 10Log(\frac{I}{I_o})\\\\\beta (dB) = 10Log(\frac{3.2*10^{-6}}{1*10^{-12}})\\\\\beta (dB) = 65.05 \ dB[/tex]
= 65 dB
If the decibel level goes up to 80 dB, the intensity in W/m² is given by;
[tex]\beta (dB) = 10Log(\frac{I}{I_o} )\\\\80 = 10Log(\frac{I}{I_o} )\\\\8 =Log (\frac{I}{I_o} )\\\\10^8 = \frac{I}{I_o} \\\\I = I_o *10^8\\\\I = 1*10^{-12}*10^8\\\\I = 1*10^{-4} \ W/m^2[/tex]

Which part of the expression corresponds to the cost of movie tickets in 1980?
Answers
Answer:
2.75
Step-by-step explanation:
0.10 represents the rate at which prices have increased since 1980..
2.75 represents the price in 1980
This can be confirmed by inputting 0 as the value of x.

The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd, find its area.
Answers
Answer:
all the sides multiplies should equal 48
Step-by-step explanation:
sorry I don't know
The rectangle will have a 432 yd² area.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd
Let "l " be the length of the rectangle
thus, the width of the rectangle = l/3
Since the Perimeter of the rectangle = 48 yd
From the general formula of the Perimeter of the rectangle:
perimeter = 2*(length + width)
In our case
Perimeter = 2*( l + l/3)
Perimeter = 2*(2l/3)
Perimeter = 4L/3
Thus,
4L/3 = 48
L = 36 yd
So width = 36 /3 = 12
Since the area of the rectangle = length * width
Area = 12 * 36
Area = 432
therefore, the area of the rectangle will be 432 yd².

m<2 = (10x - 18)
Required:
Value of x
Solution:
<1 and <2 are alternate exterior angles. Alternate exterior angles are congruent. Therefore:
m<1 = m<2
8x = 10x - 18 (substitution)
Solve for x
8x - 10x = -18
-2x = -18
-2x/-2 = -18/-2
