What is a scale factor of 4?
The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure
What is a scale factor of 4?Scale factors in geometry are defined as a conversion factor for distances in similar shapes, so the scale factor is the factor you would have to multiply all of the dimensions of one shape by in order for it to have the same dimensions as the other, so a scale factor of 4 means that if you multiplied all of the dimensions of one shape by 4, they would be the same dimensions as the dimensions of the other.
Alternatively, if this is not involving another shape, a scale factor of 4 is merely a factor for dilation, the transformation that makes a shape larger, therefore a scale factor of 4 would simply need you to multiply all of the original’s dimensions.

What are the 3 ways to calculate slope?
There are several ways to calculate the slope of a line, but the most common ways are:
Rise over Run: This is the most basic and intuitive way to calculate slope. It involves taking the difference in the y-coordinates (rise) and dividing it by the difference in the x-coordinates (run) between two points on the line. The slope is represented by the letter "m" and can be calculated using the following formula: m = (y2 - y1) / (x2 - x1)
For example, if two points on a line are (3,6) and (6,9) the slope can be calculated as: m = (9-6) / (6-3) = 3/3 = 1
Point-Slope Form: This method uses the coordinates of a single point on the line and the slope of the line to find the equation of the line. The slope is represented by the letter "m" and the point by the coordinates (x1, y1). The equation of the line in point-slope form is: y - y1 = m(x - x1)
Slope-Intercept Form: This method expresses the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept. To find the slope-intercept form, you need to know the slope and the y-intercept (the point where the line crosses the y-axis) of the line.

How to express an absolute value function as a piecewise-defined function?A piecewise-defined function is a function that is defined by multiple sub-functions, each of which applies to a certain range of the input (or domain) values.
Each sub-function is defined by a separate piece of the overall function, and together they define the entire domain of the function. The sub-functions are typically separated by breakpoints, which are values of the input variable at which the sub-functions change.
|x| can either be -x or x. Thus, the absolute value function f(x) = 6|x| can be written as:
f(x)= 6x or f(x)= -6x
Therefore, the piecewise-defined function of f(x) = 6|x| will be:

How do you find the length of the third side of a triangle for Class 7?
Answer:
To find the length of the third side of a triangle for class 7, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
The theorem can be written as: c^2 = a^2 + b^2, where c is the hypotenuse and a,b are the other two sides.
So, if you know the lengths of the other two sides, you can use this theorem to find the length of the third side. For example, if you know the lengths of sides a and b, you can use the following formula to find the length of side c: c = √(a^2 + b^2)
You can also use the converse of the Pythagorean theorem, which states that if the square of the length of one side is equal to the sum of the squares of the other two sides, the triangle is a right triangle.
It is always a good idea to draw a diagram to help you understand the problem and to double check the answer.

Ron and his friends like to send messages to one another. One evening, Ron estimated how many messages he'd sent that day. When he looked at his phone, he saw he'd sent 25 messages. His estimate had been 40% more than that. How many messages did Ron estimate he'd sent?
We know that Ron's estimate for the number of messages he sent that day was 40% more than the actual number of messages he sent. To find out how many messages he estimated he sent, we need to undo this percentage increase.
If the actual number of messages Ron sent was 25, and his estimate was 40% more than that, we can use the following equation:
Estimated number of messages = Actual number of messages + (Actual number of messages * 40%)
We can then substitute in the known values and solve for the estimated number of messages:
Estimated number of messages = 25 + (25 * 40%)
Estimated number of messages = 25 + (25 * 0.4)
Estimated number of messages = 25 + 10
Estimated number of messages = 35
Therefore, Ron estimated that he sent 35 messages that day.

The two numbers are either 0 and 1 or 1 and 0. This is a method of solving a system of equations called substitution method
To solve this problem you can use a mathematical one, called a system of equations. A system of equations is a set of two or more equations that contain multiple variables. In this case, we have two equations with two variables, x and y.
We know that when you add the two numbers, the result is 1. We also know that when you multiply the two numbers, the result is 0.
Given these two equations:
x + y = 1 and x*y = 0
We know that one of the numbers is 0, because when we multiply any number by 0 the result is 0.
So x=0 or y=0
Now we can use the first equation, x + y = 1, and substitute in one of the values we know:

The simplest way to solve the system of equations 7x + 5y = 19 and -7x - 2y = -16 would be using the method of c i.e Elimination.
Elimination, also known as the method of adding or subtracting equations. This method involves adding or subtracting the equations in such a way that one of the variables is eliminated, making it easier to solve for the other variable.
Here is one way to solve the system of equations 7x + 5y = 19 and -7x - 2y = -16 using the elimination method:
Add the two equations together:
(7x + 5y) + (-7x - 2y) = 19 + (-16)
This eliminates the x variable and gives you:
3y = 3
Divide both sides of the equation by 3 to get:
y = 1
Substitute this value of y back into one of the original equations (either 7x + 5y = 19 or -7x - 2y = -16) to find the value of x. For example, using the first equation:
7x + 5(1) = 19
7x + 5 = 19

A percentage is a dimensionless number (pure number); it has no unit of measurement.
The term "percent" is derived from the Latin per centum, meaning "hundred" or "by the hundred". The sign for "percent" evolved by gradual contraction of the Italian term per cento, meaning "for a hundred". The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to two circles separated by a horizontal line, from which the modern "%" symbol is derived.

what is function ?
The study of mathematics comprises the study of quantities and their variations, equations and associated structures, shapes and their positions, and locations where they can be found. A combination of inputs and corresponding outputs are referred to as a "function," which describes the relationship between them. The term "function" refers to an association between inputs and outputs where each input produces a single, unique result. There are two domains, or scopes, assigned to each function. Usually, the symbol f is used to signify functions (x). input is an x. There are four basic categories of functions that are available: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

Let y=x^x
⇒ dx/dy =x ^x (1+logx)
For increasing function, dx/dy >0
⇒x ^x (1+logx)>0
⇒1+logx>0
⇒log e
x>log e/e
⇒x> 1/e
Therefore, the function is increasing, when x> 1/e
The claim about the function that is false is At x = 1 and x = -1, respectively, the function has a local minimum and a local maximum.

Determine the equation of a straight line passing through (-1,3) and parallel to the line whose equation is 3x-5y=10.
Answer:
y = (3/5)x+3.6
Step-by-step explanation:
Let's look for an equation of the standard form: y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is 0). Parallel lines have the same slope, m. Next, rearrange the reference line to standard format:
3x-5y=10
-5y = -3x + 10
y = (3/5)x + 2
Now we can easily find the slope. The slope of the reference line is (3/5). That will also be the slope of the parallel line, so we can write:
y = (3/5)x + b
We need a value of b that will shift the line so that it touches point (-1,3) . ["passes through"]. Enter that point into the above equation and solve for b:
y = (3/5)x + b
(3) = (3/5)*(-1) + b for point (-1,3)
3 = -(3/5) + b
-(3/5) = 3-b
-b = -3 - (3/5)
b = 3+(3/5)
b = (18/5), or 3.6
The equation becomes y = (3/5)x+3.6
See the attached graph.
[Parallel lines have a lot in common. Too bad they'll never meet.]
