What is equation?An equation is an expression that states the equality of two mathematical quantities. It usually involves a set of mathematical symbols, such as an equal sign, numbers, and operators, which represent the relationship between the two sides of the equation. Equations are used to solve a variety of mathematical problems, ranging from simple equations to complex systems of equations.
We can solve this equation by using the Quadratic Formula.
The Quadratic Formula states that x = (-b ± √(b² - 4ac))/(2a).
In this equation, a = 1, b = 6, and c = -5.
Therefore, x = (-6 ± √(6² - 4(1)(-5))/(2(1))
x = (-6 ± √36 + 20)/2
x = (-6 ± √56)/2
x = (-6 ± √7(8))/2
x = (-6 ± 8)/2
x = (m = -14/2) + (n = 8/2)
Therefore, the solutions of the equation x² + 6x - 5 = 0 are m = -7 and n = 4.

where :
a is the coefficient of [tex]x^{2}[/tex]
b is the coefficient of x
c is the constant term
To solve this equation there are several ways to do. One of the way is by factor.
For example :
[tex]x^{2} +7x + 10 = 0[/tex]
From above equation we search for factor. Assume they are a and b.
a. If a x b, the result will be 10
b. If a + b , the result will be 7
As we know that factor of 10 is 1, 2, 5, 10.
The best answer for those equation will be a = 2 and b = 5
[tex]x^{2} + 7x +10 = 0[/tex]
( x + 5 )( x + 2 ) = 0
x = -5 or x = -2

How many solutions does a system of linear equation in two variables has if the?
There are infinitely many possible solutions to a two-variable linear equation. Every point which is a straight line, represents a solution to a linear equation with two variables.
What exactly are equation systems?In algebra, multiple equations are referred to as simultaneous equations or systems of equations because they must be solved simultaneously (the solution must satisfy each system of equations). For a system to have a singular solution, there must be an equal number of unknowns and equations. When there are enough data to construct equations from multiple unknowns, systems of equations are used to solve problems. When there are n unknowns, we typically require sufficient knowledge to formulate an equation for each one.
Thus, a system of linear equations with two variables has infinitely many solutions.

Nancy purchased some bed
sheets that cost $36. They were
on sale 25% off. What is the
new price of the bed sheets?
Answer:
To find the new price of the bed sheets, we can calculate the amount of discount first and then subtract it from the original price.
The bed sheets were on sale 25% off, so the amount of discount is:
$36 x 25/100 = $9
To find the new price of the bed sheets, we can now subtract the discount from the original price:
$36 - $9 = $27
So the new price of the bed sheets is $27.
Answer:
$36 * 0.75 = $27. That is the answer.
If 1.00 is 100 percent, subtract 0.25 or 25 percent from that to get 0.75 or 75 percent as the value which is left then multiply the original price, $36 to get the equation and answer above.

What is probability?
Probability denotes the likelihood of something happening. It is a mathematical discipline that deals with the occurrence of a random event. The value ranges from zero to one. Probability has been introduced in mathematics to predict the likelihood of occurrences occurring. Probability is defined as the degree to which something is likely to occur. This is the fundamental probability theory, which is also utilised in probability distribution. To determine the likelihood of a particular event occurring, we must first determine the total number of possibilities.

How do you graph vertical and horizontal shifts?
To graph a vertical shift, take the original graph and move it up or down on the y-axis. To graph a horizontal shift, take the original graph and move it left or right on the x-axis.
Vertical shifts can be graphically represented by taking the original graph and moving it up or down on the y-axis. This is accomplished by adding a constant value to every y-value in the equation. For example, if the equation is y = x + 2, shifting the graph up two units on the y-axis would change the equation to y = x + 4. Horizontal shifts can be graphically represented by taking the original graph and moving it left or right on the x-axis. This is accomplished by adding a constant value to every x-value in the equation. For example, if the equation is y = x + 2, shifting the graph two units to the right on the x-axis would change the equation to y = x - 2. When graphing vertical or horizontal shifts, it is important to remember that the overall shape of the graph remains the same, only the position of the graph changes.

much is the finance charge after the following purchases and payment for a single
billing period? Assume no balance brought forward from the prior month. Round all
dollar amounts to the nearest penny.
The finance charge after the purchases and payment for a single billing period is $12.38.
What is the finance charge?The finance charge is the multiplication of the average daily balance and the monthly periodic rate.
To calculate the finance charge for a single billing period, we need to determine the average daily balance and then multiply that by the daily rate and the number of days in the billing period.
Here's the calculation:
Purchase 1: $100
Purchase 2: $200
