What is the relationship in which the ratio of the manipulated variable and the responding variable is constant group of answer choices?

What is the relationship in which the ratio of the manipulated variable and the responding variable is constant group of answer choices?

The answer is letter B. When the ratio of the manipulated variable and responding variable is constant, this suggests that as one variable increases, the other variable also increases, and vice versa. This relationship displays a directly proportional one.

What is an experiment in which only one variable is manipulated at a time?

experiment in which only one variable is manipulated at a time is called a controlled experiment.

What are the three types of variables?

There are three main variables: independent variable, dependent variable and controlled variables. Example: a car going down different surfaces.

How do you separate variables and constants in algebraic expressions?

The basic building blocks of an Algebraic expression are variables and constants and operating symbols such as plus, minus signs. Algebraic expressions are just a set of variables and constants that are separated by plus or minus signs.

What is like terms in algebraic expression?

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

What are the terms of an algebraic expression?

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables. Each term in an algebraic expression is separated by a + sign or J sign. In , the terms are: 5x, 3y, and 8.

How do you find the GCF of an expression?

Finding a GCF. To factor out the GCF in an expression like the one above, first find the GCF of all of the expression’s terms. Next, divide each term from the original expression (3×3+27×2+9x ) by the GCF (3x), then write it in the parenthesis.

What is variable What are the rules for defining variables?

All variable names must begin with a letter of the alphabet or an underscore(_). After the first initial letter, variable names can also contain letters and numbers. Variable names are case sensitive. No spaces or special characters are allowed. You cannot use a C++ keyword (a reserved word) as a variable name.
