 Algebra 1 is a foundational math course that introduces students to the basic concepts of algebra. Algebra is a branch of mathematics that deals with symbols and the rules for manipulating them. Algebra 1 covers a wide range of topics, including linear equations, inequalities, systems of equations, polynomials, rational expressions, quadratic equations, radical expressions, exponential and logarithmic functions, and trigonometry.

Algebra 1 is an important course because it provides students with the foundation they need for success in more advanced math courses, such as Algebra 2, Geometry, and Calculus. Algebra 1 is also used in many other fields, such as science, engineering, and business.

## Algebra 1 Problems and Answers

### Linear Equations

Linear equations are equations of the first degree. They can be represented in slope-intercept form, point-slope form, and standard form.

• Slope-intercept form: y = mx + b
• Point-slope form: y – y1 = m(x – x1)
• Standard form: Ax + By = C

To solve a linear equation, you can use substitution, elimination, or graphing.

### Linear inequalities

Linear inequalities are equations that involve a less than or greater than sign. They can be represented in slope-intercept form, point-slope form, and standard form.

To solve a linear inequality, you can use the same methods that you use to solve a linear equation. However, you also need to consider the direction of the inequality symbol.

### Systems of equations

A system of equations is two or more equations that are solved simultaneously. Systems of equations can be solved using substitution, elimination, or graphing.

### Polynomials

A polynomial is an expression that consists of variables and coefficients. Polynomials can be classified by their degree, which is the highest exponent of any variable in the polynomial.

Basic operations with polynomials include addition, subtraction, multiplication, and division. Polynomials can also be factored into smaller polynomials.

### Rational expressions

A rational expression is an expression that is the quotient of two polynomials. Rational expressions can be simplified by canceling out common factors and factoring the numerator and denominator.

A quadratic equation is an equation of the second degree. It can be represented in standard form, vertex form, and factored form.

To solve a quadratic equation, you can use the quadratic formula, factoring, or completing the square.

A radical expression is an expression that contains a radical. Radicals can be simplified by combining like terms and rationalizing the denominator.

### Exponential and logarithmic functions

An exponential function is a function of the form f(x) = a^x, where a is a positive constant. A logarithmic function is the inverse of an exponential function.

Exponential and logarithmic functions have many properties that can be used to solve equations and inequalities.

### Trigonometry

Trigonometry is the study of triangles and their properties. The basic trigonometric functions are sine, cosine, and tangent.

Trigonometric functions can be used to solve problems involving right triangles and other shapes.
