## How do you know if an equation is linearly independent?

Now, if we can find non-zero constants c and k for which (1) will also be true for all x then we call the two functions linearly dependent. On the other hand if the only two constants for which (1) is true are c = 0 and k = 0 then we call the functions linearly independent.

## How do you describe the independent variable?

An independent variable is defines as the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable.

## What is the difference between a dependent and independent variable?

You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.

## What is the dependent variable Why?

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it “depends” on the independent variable.

## How do you write an equation with infinitely many solutions?

In this case, the idea is that you have to create something that makes both the right side of the equation and the left side to be equal to each other which gives you an infinite number of solutions. so if you have 5x-8 on the left, you need 5x-8 on the right for everything to cancel and end up with 0=0.

## How do you know if a graph is independent or dependent?

If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

## What is the independent variable on a table?

Always set up your table so the Dependent Variable is the column variable and the Independent Variable is the row variable.

## What type of solution is 0 0?

infinite solution

## What are infinitely many solutions?

Having infinitely many solutions means that you couldn’t possibly list all the solutions for an equation, because there are infinite. Sometimes that means that every single number is a solution, and sometimes it just means all the numbers that fit a certain pattern.

## Is height an independent variable?

the average height of adults might give you a graph as shown below. The independent variable is average height. The dependent variable is weight. For example, height might be an independent variable in the context stated above but a dependent variable in a study on the effect of nutrition on growth rates.

## How do you know if two equations have no solution?

The coefficients are the numbers alongside the variables. The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

## What does infinite solution look like?

An infinite solution has both sides equal. For example, 6x + 2y – 8 = 12x +4y – 16. If you simplify the equation using an infinite solutions formula or method, you’ll get both sides equal, hence, it is an infinite solution.

## How do you remember independent and dependent variables?

Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense.

## How do you choose independent variables?

An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.

## Is pressure an independent variable?

Explanation: If you manipulated (changed) the pressure and measured the volume as a result, the pressure would be the independent variable and the volume would be the dependent variable because the volume was dependent on the pressure.

## What is the independent variable in a bar graph?

The independent variable here is the YEAR and it is plotted on the horizontal axis. The dependent variable is the AVERAGE HEIGHT and this is plotted on the vertical axis. The height is a dependant variable because we are trying to determine a relationship between the year and the height.

## What type of data is the dependent variable?

Dependent variables are the measured behaviors of participants. They are dependent because they “depend on” what the participants do. The most obvious example is text entry speed, measured, for example, in words per minute.

## How do you know what the dependent variable is?

The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value.

## What is a dependent variable in an experiment?

The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.

## Is temperature an independent variable?

An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.

## What is the Independent in an experiment?

Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.

## Where does the independent variable go on a graph?

The Axes. The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

## How do you know if a system has no solution?

A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel. Infinite solutions.

## Is water a dependent variable?

The dependent variable is usually what scientists measure in an experiment. In this case, the amount of water is the independent variable because that is what you’re changing in the experiment: one seed gets a lot of water and the other seed only gets a little water.

## How do you know if a system has infinitely many solutions?

If a system has infinitely many solutions, then the lines overlap at every point. In other words, they’re the same exact line! This means that any point on the line is a solution to the system. Thus, the system of equations above has infinitely many solutions.

## How do you know if something has infinitely many solutions?

An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.

## What is the difference between no solution and infinitely many solutions?

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. Note that we have variables on both sides of the equation.
