What are the linear equations in two variables?When a, b, and c are all real values and the coefficients of x and y, i.e., a and b, are not equal to zero, the equation is said to be linear in two variables. A few more examples of two-variable linear equations are 10x+4y = 3 and -x+5y = 2.
What is a linear equation in math?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Let's say that "x" cans of soup and "y" frozen meals were purchased.
We may create the equations based on the above conditions,
x + y = 15 ————(I) (I)
200x + 500y = 4500 ——-(II) (II)
Now, y = 15 - x from (I).
If you change the value of "y" in equation (II), you obtain
200x + 500(15 - x) = 4500
200x + 7500 - 500x = 4500
300x = 3000
x = 3000/300
x = 10
In equation (I), x = 10 results in
y = 5
The result is that 10 cans of soup and 10 frozen dinners were bought.

B) The y-intercept represent the constant variable.
What is y-intercept?
In mathematics, the intersection point is the point on the y-axis through which the slope of the line passes. The y-intercept is where the line or curve intersects or touches the y-axis. This is the vertical, often dark line in the middle of the chart. The y-intercept of a chart is the point where the chart intersects the y-axis. Y-INTERCEPT means the y-coordinate of the point where the line, curve, or surface intersects the y-axis.
in given problem take number of text represent as x coordinate and cost of month represent y coordinate , then
[tex](x_1,y_1)=(45,37.25)\\(x_2,y_2)=(118,40.90)[/tex]
Now using slope formula ,
slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
=> slope m = 3.65/73 = 0.05
Now using equation formula ,
[tex]y-y_1=m(x-x_1)[/tex]
=> y-45 = 0.05(x-37.25)
=> y-45 = 0.05x-1.8625
=> y= 0.05x+45-1.8625
=> y = 0.05x+43.13
Here we know that equation general form is y = mx+b , where b is

Drake ha been feeding hi hore after chool thi week. There were 3 day that Drake fed hi hore 12 pound of hay. Another day Drake fed hi hore 11 2/5 pound of hay. The lat day Drake fed hi hore 10. 82 pound. How many pound in total did Drake feed hi hore thi week? Write your anwer in decimal and in fraction
The total Drake feed his horse this week is 58.22 pound or 58[tex]\frac{11}{50}[/tex] pound.
How to calculate total pounds?Let's break it down,
day 1 = 12 pound
day 2 = 12 pound
day 3 = 12 pound
day 4 = 11[tex]\frac{2}{5}[/tex] pound
day 5 = 10.82 pound
First to answer in decimal, change all value to decimal. Since only day 4 value is not decimal, so we only change day 4 value.
day 4 = 11 + (2 ÷ 5) = 11.4 pound
Total pound = 12+12+12+11.4+10.82
= 58.22 pound
Next, to answer in fraction, we only change the result in decimal to fraction. So,
58.22 = 58 + (22 ÷ 100)
= 58[tex]\frac{22}{100}[/tex]
simplified
= 58[tex]\frac{11}{50}[/tex]
Thus, this week Drake feed his horse 58.22 pound of hay or equal to 58[tex]\frac{11}{50}[/tex] pound of hay.

What is inequality ?
Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.
In this case, the inequality 2x - 3y <12
Related formula: 2x - 3y = 12.

Having $21,000 after investing 11 years with an annual simple interest rate of 4.5% means that the principal amount that Cindy's mom invested when Cindy turned 10 years old was $14,046.82
Simple interest rate is calculated by multiplying the interest rate given in a period of time with the principal without any compounding, and multiply it by the period of time that the principal is invested.
Given that the interest rate is at 4.5% annually, we will need to convert the percentage into a decimal with the following calculation:
4.5/100=0.045
The principal is invested when Cindy was 10 years old and by the time Cindy turned 21 years old the total investment accumulated is $21,000 within 11 years. We will then need to figure out the initial amount invested with the following formula:
P = A / (1 + rt)
Where P is the principal amount, A is the total amount of principal including the interest, r is the interest in decimal, and t is the number of years the money is invested.
P = 21000/(1+(0.045×11))

What is the solution to the systems?.
A solution to a system of equations is a value that, when substituted for unknown variables, causes the equations to be true.
A system of linear equations is made up of two or more linear equations made up of two or more variables, and all equations in the system are considered at the same time.
The set of all values that, when substituted for unknowns, make the equations true is referred to as the solution of a system of equations.
To find the unique solution to a system of linear equations, we must find a numerical value for each variable in the system that simultaneously solves all of the equations in the system.
Some linear systems have no solution, while others have an infinite number of solutions.
There are three types of two-variable linear equation systems and three types of solutions.
An independent system only has one solution pair (x,y). The only solution is where the two lines intersect.A system that is inconsistent has no solution. Take note that the two lines are parallel and will never cross.And the dependent system of equations has an infinite number of solutions. The lines are parallel. Because they are the same line, every coordinate pair along it is a solution to both equations.As a result, a solution to a system of equations is a value that, when substituted for unknown variables, causes the equations to be true.

Height = ?
Length of Base = ?
The dimension of the Box is equal to 3×6×6 where the Height = 3m and the length of base = 6m
We have the volume of the box as
V= 108 cubic meters
Let 'a' be the height of the box and 'b' be the one side of the base of the box.
Therefore the formula for volume is
Volume = ab²
108 = ab²
=> a = 108/b² ....(1)
Now the surface area of the box is,
S = b² + 4ab ....(2)
From equations (1) and (2) we get,
Sa = b² + 4× (108/b²) × b
Sa = b² + 432 / b² ....(3)
Now for the least possible surface area differentiate equation (3) we get,
d(Sa)/db = 2b - 432/b² ....(4)
Now put the equation (4) equal to zero we get,
2b - 432/b² = 0
2b = 432/b²
b³ = 216
b = 6

can someone help i dont understand this
p(n)=2n; find p(-1)
The solution for p(-2) in the function when the function p(n) = 2n is -2
How to determine the solution for p(-1) in the function?From the question, we have the following equation that can be used in our computation:
p(n)=2n
To make the equation legible, we need to rewrite it
So, we have the following representation
p(n) = 2n
Also from the question, we have
p(-1)
This means that the value of n is -1, and we calculate p(n) when n = -1
Substitute the known values in the above equation, so, we have the following representation
p(-1) = 2 * -1
So, we have the following equation
p(-1) = 2 * -1
There is no constant to add or subtract to both sides of the equation
So, we have the following representation
p(-1) = -2
Hence, the solution is -2

A circle has a diameter with endpoints at â€""2 i and â€""6 â€""11i. what is the center of the circle? â€""8 â€""10i â€""4 â€"" 5i â€""2 â€"" 6i 2 i
The circle's center is located at (-4 -5i).
Given data,
A circle has a diameter with endpoints at -2 + i and -6 -11i.
(x₁, x₂) = (-2, -6)
(y₁, y₂) = (i, -11i)
To find what is the center of the circle;
It can be calculated by,
Add the two 'x' coordinates together and average, and the two 'y' coordinates together and average.
Now,
(x₁ + x₂)/2 = (-2 -6)/2
= -8/2
= -4
(y₁ + y₂)/2 = (i - 11i)/2
= -10i/2
= -5i
Hence, the center of the circle is at (-4 -5i).

A square rug has an inner square in the center. The side length of the inner square is x inches, and the width of the outer region is 3 in. What is the area of the outer part of the rug?
Answer:
[tex]12x+36[/tex] in²
Step-by-step explanation:
The area of the inner square is [tex]x^2[/tex] in².
The area of the whole square is [tex](x+6)^2[/tex] in².
Taking the difference, [tex](x+6)^2-x^2=(6)(2x+6)=12x+36[/tex] in².
Answer:
[tex]\huge\boxed{\sf 12x + 36 \ in.^2}[/tex]
Step-by-step explanation:
Formula:Area of square = length²Area of inner part of the rug:Length = x in.
So,
Area = (x)²
Area = x² in.²
Area of the whole rug:Length of the whole rug = 3 + x + 3 = x + 6
So,
Area = (x + 6)²
Area = x² + 12x + 36 in.²
Area of the outer part of the rug:= Area of the whole rug - Area of the inner part
= x² + 12x + 36 - x²
= x² - x² + 12x + 36
= 12x + 36 in.²[tex]\rule[225]{225}{2}[/tex]
