## Study Notes

### Solving for Variables

- Involves removing parentheses and grouping terms in an expression.
- For example: (2x³y)(6x²y⁴) simplifies to 12x⁵y⁵ through multiplication:
- Combine coefficients: 2 * 6 = 12
- Combine like variables: x³ * x² = x⁵ and y * y⁴ = y⁵.

### Solving Algebraic Expressions

- Process includes solving for exponents and grouping like terms.
- It is essential to organize terms before attempting to solve.

### Negative Exponents

- Negative exponents indicate division rather than multiplication.
- For example:
- 5⁻² equals 1/5² = 1/25.

### Systems of Equations Word Problems

- Typically structured with the equations:
- x + y = total
- ax + bx = cost

- Variables a and b represent quantities associated with x and y.

### Elimination

- A method to solve systems of equations by eliminating one variable.
- After eliminating, substitute the found value back into another equation to solve for the remaining variable.

### Point-Slope Form

- The point-slope form of a linear equation is expressed as:
- y - y₁ = m(x - x₁)

- Where (x₁, y₁) is a specific point on the line and m represents the slope.
