What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept, the point where the line intersects the y-axis. This form makes it easy to identify the slope and y-intercept of a line by simply looking at the equation.

How do you find the area of a triangle?

To find the area of a triangle, you can use the formula: Area = 1/2 * base * height. Simply plug in the length of the base and the height of the triangle into the formula and calculate the result. It's important to ensure that the base and height are perpendicular to each other for an accurate calculation of the triangle's area.

What is the difference between a plant and an animal cell?

The main differences between a plant cell and an animal cell are that plant cells have a cell wall, chloroplasts for photosynthesis, and a large central vacuole, which animal cells lack. Additionally, plant cells typically have a more rectangular shape compared to the rounder shape of animal cells.

How do you simplify an algebraic expression?

To simplify an algebraic expression, combine like terms by adding or subtracting coefficients of the same variables. Also, use the rules of exponents to simplify terms with variables raised to powers. Then, follow the order of operations to simplify any remaining arithmetic operations within the expression. Finally, rewrite the expression in its simplest form by combining like terms and simplifying any remaining operations.

What is the definition of a factor in math?

In mathematics, a factor is a number or quantity that divides another number or quantity without a remainder. It is a divisor of the original number, meaning it can be multiplied by another number to yield the original number. Factors play a crucial role in arithmetic operations such as multiplication and division.

How do you find the volume of a rectangular prism?

To find the volume of a rectangular prism, you multiply its length, width, and height together. The formula for the volume of a rectangular prism is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the prism. Simply plug in the measurements of the length, width, and height into the formula and multiply the numbers together to calculate the volume of the rectangular prism.

What are the three branches of the US government?

The three branches of the US government are the executive branch, the legislative branch, and the judicial branch.

How do you solve a system of equations using substitution?

To solve a system of equations using substitution, you first solve one of the equations for one variable in terms of the other variable. Then, substitute this expression into the other equation to get an equation with only one variable. Solve this equation for the remaining variable. Finally, substitute this value back into one of the original equations to find the value of the other variable. This method helps to find the values of both variables in the system of equations.

What is the difference between a physical change and a chemical change?

A physical change is a change in the physical properties of a substance without changing its chemical composition, such as a change in size, shape, or state. On the other hand, a chemical change is a change in the chemical composition of a substance, resulting in the formation of new substances with different properties. Physical changes are usually reversible, while chemical changes are often irreversible.

How do you calculate the probability of an event?

To calculate the probability of an event, you divide the number of favorable outcomes by the total number of possible outcomes. The formula for probability is: P(event) = Number of favorable outcomes / Total number of possible outcomes. Multiply the result by 100 if you want to express it as a percentage. This method applies to both simple and compound events in probability theory.
