The variables are unknown, coefficients are numbers in multiplication with those unknown variables and constants are solo standing numbers.
Thus, we have:
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.

The formula that is useful for solving both of these problems is ...
9. Given v₁=15, a=9.8, d=10, find v₂.
... (v₂)² = 15² + 2·9.8·10
... v₂ = √421 ≈ 20.5 . . . . m/s
10. Given d=12 m when a=-9.8 m/s² and v₂=0, find d when a=0.17·(-9.8 m/s²).
The formula tells us that d=(v₁)²/(2a), which is to say that the distance is inversely proportional to the acceleration. If acceleration is 0.17 times that on earth, distance will be 1/0.17 ≈ 5.88 times that on earth.
(12 m)/0.17 ≈ 70.6 m
