Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Write a mathematical model for the problem and solve. One positive number is 1/5 of another number. The difference between the two numbers is 52. Find the numbers.
Given that the first number is one fifth of the second number.
So consider the second number as x.
