How do you find the cost of one item from a system of equations?

Back

To find the cost of one item, set up a system of equations based on the total costs and quantities purchased, then solve for the variables.

Front

What is the quadratic formula?

Back

The quadratic formula is used to find the solutions of a quadratic equation in the form ax² + bx + c = 0. It is given by x = (-b ± √(b² - 4ac)) / (2a).

Front

What does the vertex of a parabola represent in a quadratic function?

Back

The vertex of a parabola represents the maximum or minimum point of the quadratic function, depending on the direction of the parabola.

Front

What is exponential decay?

Back

Exponential decay describes a process where a quantity decreases at a rate proportional to its current value, often modeled by the equation y = a(1 - r)^t.

Front

How do you determine the solution set of a system of inequalities?

Back

To determine the solution set, graph each inequality on the same coordinate plane and identify the region where the shaded areas overlap.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0.

Front

What does it mean for a function to be quadratic?

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c, where a ≠ 0.

Front

How can you interpret the slope of a line in a real-world context?

Back

The slope of a line represents the rate of change between two variables, indicating how much one variable changes for a unit change in another.

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula A = 1/2 * base * height.
