Judy needs 1 5/8 yards area more of flannel to stitch the kirt.

To find how much more fabric Judy needs, we need to subtract the amount she already has from the amount she needs.

Judy needs 2/3 yard of flannel

Judy has 3/8 yard of flannel

To subtract these fractions, we first need to convert them to the same denominator.

2/3 yard = 4/6 yard

3/8 yard = 6/8 yard

4/6 yard - 6/8 yard = (24 - 24)/48 = 0/48

To simplify, 0/48 = 0

Therefore, Judy needs 0 yards more of flannel.

However, Judy needs 2/3 yard of flannel to stitch the kirt. Since she has 3/8 yard, we can subtract the two to find how much more fabric she needs.

2/3 yard - 3/8 yard = (16 - 12)/24 = 4/24

To simplify, 4/24 = 1/6

Therefore, Judy needs 1 1/6 yards area more of flannel to stitch the kirt.

Answer:

1. (0,2)

2. (-2,-1)

Step-by-step explanation:

1.

y = 2x + 2

y = x + 2

2x + 2 = x + 2

2x = x

x = 0

Now we put 0 back in for x and solve for y

y = 2(0) + 2

y = 2

So, our answer for Q1 is (0,2)

2.

y = 3x + 5

y = -x - 3

3x + 5 = -x - 3

4x + 5 = -3

4x = -8

x = -2

Now we put -2 back in for x and solve for y

y = 3(-2) + 5

y = -6 + 5

y = -1

So, our answer for Q2 is (-2,-1)

Steps to find the equation of a line with 2 points mentioned below:

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, first determine the slope and y-intercept. The ratio of y to x is known as the slope. A slope triangle should be drawn connecting any two spots you find along the line.

To determine a line's equation from two points following steps are there:

1. Determine the slope and used the slope formula.

Slope(m) = (y₂ - y₁) / (x₂ - x₁)

2. To determine the y-intercept, use the slope and one of the points(b).

The x and y in your equation y = mx + b may be replaced by one of your locations, and the m can be replaced by the slope you just computed. The only variable remaining is b in such case. To solve for b, use the same methods you would to solve for a variable.

3. Once you have the values for m and b, you can use them to solve for the line's equation in the slope-intercept form (y = mx + b).

Two or more expressions with an Equal sign is called as Equation.

To get the cash due at signing, we just add up the following quantities:

Down payment = $3300

First Monthly payment = $475

Security deposit = $475

Acquisition fee = $500

Hence the total cash due at signing is calculated as follows:

(Total cash due at signing) = (Down payment) + (First Monthly payment) + (Security deposit) + (Acquisition fee)

= $3300 + $475 + $475 + $500

Change to base 5 can be done by dividing the decimal number by 5 and then taking the remainder of the division in reverse order.

The number base is the number that forms the basis for the formation of other numbers in a number system.

The number base that we use a lot every day is the decimal system, which consists of 10 numbers, from 0 to 9. This decimal system is usually called the base 10 number system. Apart from base 10, there are also other base systems, for example, base 2 (biner system), 8 (octal system), and 16 (hexadecimal system) which are usually used in computer / digital systems.

Change of base 10 numbers to other base numbers is done by:

For example, we want to change 214₁₀ to a base 5 number:

214 : 5 = 42 remainder 4

42 : 5 = 8 remainder 2

8 : 5 = 1 remainder 3

1 : 5 = 0 remainder 1

The four transformations of a function are translation, reflection, stretching/shrinking, and rotation.

Function is a group of related statements that perform a specific task. It is a block of organized, reusable code which can be used to perform a single, related action. Functions help make code more reusable and efficient. It also reduces the complexity of a program by breaking it down into smaller and simpler parts.

Translation involves shifting the graph of a function along a given axis; reflection involves flipping the graph of a function about a given axis; stretching/shrinking involves changing the scale of a graph along a given axis; and rotation involves rotating the graph of a function about a given point. All of these transformations can be used to modify the graph of a function, allowing for a variety of different outputs.

The inverse of the equation y = - 4x + 3 is y = (3 - x)/4.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, An equation y = - 4x + 3.

To find the inverse we'll first solve for 'x'.

Therefore,

y = - 4x + 3.

4x = 3 - y.

x = (3 - y)/4.

Now, we'll interchange the positions of 'x' and 'y'.

Therefore,

x = (3 - y)/4 becomes,

Answer:

The y-intercept of an equation is the point where the line crosses the y-axis, i.e when x = 0.

In this case, the cost equation is C = 2x + 180, where C is the total cost and x is the number of board games produced.

So when x = 0, C = 2(0) + 180 = 180

Therefore, the y-intercept of the cost equation is (0,180)

So the y-intercept of the cost equation is 180.

If the system consists of 2 variables we can use the method of elimination or substitution to get the answer easily.

In the method of elimination from the two given sets of equations, we make one of the coefficients of a variable the same so that when in the next step when we will subtract them they will get canceled out and we will get the value of one of the variables which after substituting in one of the equation we'll get the value of another variable.

If we have more than 2 variables the method of row reduction using a matrix is the best way to solve the system. In the system we make an augmented matrix of the coefficients of the variables and row reduce them in such a way that when we multiply the matrix with the row matrix we get the values of the variables easily.

By solving the linear equation in x Abebi receives $37.

An equation is said to be linear if the maximum 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. Here, A is a coefficient, B is a constant, and x is a variable.

On identifying the information given in the problem we have:

Abebi, Bella, and Chuku share $112. Abebi receives $x. Bella receives $12 less than Abebi. Chuku receives twice as much as Bella.

On setting up an equation using the information given:

We know that the total amount shared is $112 and we want to find out how much Abebi receives, represented by x.

We know that:

Bella receives $12 less than Abebi =(x - 12)

Chuku receives twice as much as Bella =(2 * (x - 12))

So we can set up the equation as:

x + (x - 12) + (2 * (x - 12)) = 112

On simplifying the equation:

x + x - 12 + 2x - 24 = 112

Combining like terms:

4x - 36 = 112

On solving for x we get:

Add 36 to both sides:

4x = 148

Divide both sides by 4:

x = 37

On interpreting the solution we get:

By solving the linear equation in x Abebi receives $37.

The process for converting 2D data to 3D data involves a few steps. First, a 3D model needs to be created, which is typically done using a 3D modeling software such as Blender or 3DS Max.

Data in math is information that can be used to draw conclusions or make decisions. It is typically collected, analyzed, and presented in the form of numbers, graphs, or tables. Data can be used to compare and contrast different scenarios, identify trends and patterns, or make predictions about the future. Data can also be used to help researchers develop hypotheses and develop models to explain phenomena.

Once the model is created, the data needs to be imported into the software in a format that can be used by the software, such as an .obj or .3ds file. The data can then be manipulated within the software to create the 3D model. Finally, the 3D model can be exported in a variety of file formats, such as .stl, .fbx, or .dae, that can be used for 3D printing, virtual reality, and other applications.
