What is a function? What is equation modelling? What is a mathematical equation and expression?
- In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function
- Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions.
Given is that Latanya has $1.90 worth of nickels and dimes. She has a total of 24 nickels and dimes altogether.
We can write the equation as -
(x/20) + (y/10) = 1.90
x + y = 24
Refer to the graph attached. On solving the equation graphically, we get-
x = 10, y = 14
Therefore, she has 10 nickels and 14 dimes in total.
