Lesson 2: Step Up
Step Up
Carefully look at this image. What do you see? Why do you think they are doing this?
What is a variable, constant term, and numerical coefficient?
Variables: is the unknown or the quantity represented by any letter. Examples: 5y+3; the letter y is the variable example: 9c; the letter c is the variable example: 2x-8; x is the variable Numerical Coefficient: the number along with the variable. It is what you multiply a variable by. example: 3y+7; the numerical coefficient is 3y is 3. example: 8c; the numerical coefficient of 8c is 8. example: 5+3m; the numerical coefficient of 3m is 3. Constant: is a number that does not change.. Example: 5+3m; 5 is the constant , it's a number by itself therefore this number never changes. Example: 4x-3; 3 is the constant term, it's a number by itself therefore it never changes. Example: 7n-5; 5 is the constant term, it's a number by itself therefore it never changes. Loading…
