From the formula or linear equation y = 7 - 9x, when x=0, y = 7.

An equation is said to be linear if the highest power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

given that y = 7 - 9x

The value of y when x=0, putting x=0 in this equation, we get

y = 7 - 9*0

y = 7 - 0

y = 7

So that the value of y = 7, when x = 0.

Amount of the check is $259.99.

Amount deposited refers to the total sum of money that is placed into a savings or investment account. This can include cash, checks, or electronic transfers. The purpose of depositing money into an account is typically to save it for future use, grow the balance through interest or other means, or to use it as collateral for loans or other financial instruments.

Depositing money into an account can be done at a bank, credit union, or other financial institution. There are different types of accounts available, including savings accounts, checking accounts, and investment accounts, each of which has its own rules and benefits.

Saving accounts typically offer low-risk, low-return options, while investment accounts may offer higher returns, but also carry more risk. Deposits into investment accounts are often made into stocks, bonds, or mutual funds. Checking accounts are typically used for day-to-day transactions, and typically do not offer high interest rates.

Regardless of the type of account, depositing money into it usually requires the account holder to provide personal information and identification, and to follow the rules and regulations set by the financial institution. The amount deposited into an account is usually insured by the government, up to a certain limit, to protect against theft, fraud, or other losses.

The amount of the check can be found by subtracting the balance brought forward from the balance carried forward.

Balance brought forward: $555.67

Balance carried forward: $295.68

Amount of the check: $555.67 - $295.68 = $259.99

In the direct variation equation y = kx, k represents the proportionality constant. Similar to this, in the inverse variation equation y = kx, k is the constant of variation.

A ratio called a constant of variation (k) shows how the independent variable (x) and the dependent variable are related to one another (y). If both of those variables have known values, you can find it by dividing y by x.

In order to obtain k given any position, we must divide the y-coordinate by the x-coordinate because k is constant (the same for every point). For instance, the variation constant is k = 3 if y changes straight as x and y = 6 when x = 2.

To graph a vertical inequality, plot the boundary line of the inequality using a solid line. Any points that are above the line represent the solution set for the inequality. To graph a horizontal inequality, plot the boundary line of the inequality using a dashed line.

A vertical inequality is graphed by plotting the boundary line of the inequality on a coordinate plane using a solid line. Points that are above the line represent the set of values that satisfy the inequality. A horizontal inequality is graphed by plotting the boundary line of the inequality on a coordinate plane using a dashed line. Points that are below the line represent the set of values that satisfy the inequality. When graphing inequalities, it is important to remember that the boundary line is not part of the solution set. Additionally, the line should be drawn in such a way that all points that satisfy the inequality are included in the solution set.

The hex representation of −5.375 is 0xB3F8.

The 16-bit FP number representation of −5. 375 has a 1-bit sign, 4-bit biased exponent, and 11-bit fraction, where bias offset = 7. The sign bit is 1, which indicates a negative number.

The biased exponent is obtained by subtracting the bias offset from the actual exponent. For -5.375, the actual exponent is -3. Subtracting the bias offset of 7 from -3 gives the biased exponent of 4, which is represented in 4 bits as 0100.

The fraction is obtained from the mantissa, which is the significant digits after the decimal point. For -5.375, the mantissa is 0.375. This can be represented in 11 bits as 1111 000 00, which gives the hex representation of 0xB3F8.

Answer:

To work this question out you need to split the shape from a complex shape to a simple shapes and finding the areas of those shapes and adding them together to get the area of the complex shape.

Looking at the figure we can make two simple shapes, a rectangle and a triangle.

To find the area of rectangle is calculated by multiplying the length and width. In this case, length is 11 and width is 8. So 11*8 = 88 cm^2.

To find the area of a triangle is by multiplying the base by the height and dividing by 2.

So for a triangle with a base of 11 and a height of 7:

(11 * 7) / 2 = 77 / 2 = 38.5

The area of the triangle is 38.5 cm^2

Therefore the area of the figure is 88 + 38.5 = 126.5cm^2

The value of k is 0, as the equations will have the same solution regardless of the value of k.

What is equation?

An equation is a mathematical statement that expresses the equality of two expressions. It consists of variables, constants, and operators that represent a relationship between the two expressions. Equations can be used to solve for unknown values, and to express relationships between different variables. Equations are a key component of mathematics, and are used to describe physical phenomena, and to analyze and predict the behavior of systems.

The value of k for which the equations do not have a unique solution is when the equations are dependent, which occurs when the equations are multiples of each other. For example, if the two equations are 2x + 6y = 10 and 4x + 12y = 20, then the equations are dependent because they are multiples of each other. In this case, the value of k is 0, as the equations will have the same solution regardless of the value of k.

For what value of k do the equations not have a unique solution?

The value of k = 9 for which the equations not have a unique solution.

A mathematical statement that expresses two expressions' equality is known as an equation. Its components—variables, constants, and operators—represent the relationship between the two expressions. Equations can be used to express relationships between various variables and to solve for unknown values. Equations are a fundamental part of mathematics and are used to explain physical phenomena as well as to examine and forecast system behaviour.

When the equations are dependent, as they are when they are multiples of each other, the value of k for which the equations do not have a single solution is called the value of k. When two equations are multiples of one another, as they are when 2x + 6y = 10 and 4x + 12y = 20, for instance, they are said to be dependent.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."

The given system of equation is:

15 - 5x + 4y = 20

10x - 5y = 40

Regroup the first equation. The first equation can be written as:

-5x + 4y = 5

In the second equation take the common term from both sides. The second equation can be written as:

5x - y = 8

Thus, the system of equation is:

-5x + 4y = 5 .... (1)

5x - y = 8 ...... (2)

From the second equation we have:

y = 5x - 8

Substitute the value of y on equation 1:

-5x + 4(5x - 8) = 5

-5x + 20x - 32 = 5

15x = 37

x = 2.4

Substitute the value of x in equation 2:
