Study Notes

Solutions and Equations

A solution to an equation is any variable value that makes the equation true.

Types of Solutions

Infinite solutions occur when linear equations are created by equating two equivalent expressions.
No solution arises in linear equations of the form ax + b, where both expressions have the same coefficient for x (a) but different constant terms (b).

Forms of Linear Equations

The general form of a linear equation is expressed as y = ax + b, where 'a' represents the slope and 'b' indicates the y-intercept.
The factored form is written as y = a(x - c), where 'a' is the slope and 'c' is the x-intercept.
Standard form is represented as Ax + By = C, with A, B, and C as real numbers, and A and B not both equal to zero.

Special Types of Equations

Literal equations are formulas or equations where variables represent specific measures.

Solving Inequalities

Solving an inequality involves several steps: representing the problem as a function, writing it as an inequality, isolating the variable to find the solution, and interpreting the outcome.

Compound Inequalities

A compound inequality combines two inequalities using "and" or "or."
Conjunction refers to joint inequalities taking the form a < x < b, representing solutions that satisfy both conditions.
Disjunction refers to inequalities structured as x < a or x > b, allowing for solutions that satisfy either inequality.
