The variables are unknown, coefficients are numbers in multiplication with those unknown variables and constants are solo standing numbers.
Thus, we have:
- Variables = z and y
- Coefficients = -8 and 12
- Constant = -7.7
- The algebraic expression
Variables, coefficients and constants in the given algebraic expression.
<h3>What is algebraic expression?</h3>Its a mathematical expression built up from integer constants, variables and algebraic operations.
<h3>What is variable?</h3>Those symbols or placeholders who may change( vary ) are called variables.
<h3>What are coefficients?</h3>Those numbers which are in multiplication with variables in the given expression are called coefficients.
<h3>What are constants?</h3>Constants are numbers who are not associated in multiplication( or division) with variables in given expression.
Thus, for given expression -8z + 12y - 7.7,
we have:
z and y as variables
-8 is coefficient of z
12 is coefficient of y
-7.7 is constant.
