You can solve the quadratic equation by using the quadratic formula, completing the square, or factoring. When you solve the quadratic equation, you find that x = -37 and 36. Since the question asked for positive integers, the only viable solution is x = 36. To solve for the larger integer, you add 1 to 36 to get an answer of 37.

Determine unknown quantities by and a quadratic equation. A. a formula for finding the solutions of a quadratic equation in standard form B. to form an approximate opinion of worth, amount,

Justify your choice. Replace y in the equation with 50: (50 = -10x2 +160x - 430) Use factoring to solve the equation. After writing the equation in standard form and dividing each side by -10, it is easy to factor as 0 = (x - 4) (x - 12). The quadratic function y = -10x2 + 160x - 430 models a store's daily profit (y), in dollars, for selling T ...

Modeling with Quadratic Equations. Marvin's pool has dimensions of 6 meters by 12 meters. He wants to put in a deck around the pool that is x feet wide to increase the total area of the pool and deck to 250 square meters. Estimate the width of the deck around the pool. Use the quadratic formula.

Create quadratic equations in one variable and use them to solve problems. Solve quadratic equations by inspection (e.g., 2=49), taking square roots, the quadratic formula, and factoring. o Justify each step in solving a quadratic equation by factoring. o Use the discriminant to determine the number of real solutions of a quadratic equation and ...

The rate of change of a function is the change in the output values compared to the change in the input values. If you look at both the table and the graph, they both represent a linear function. Linear functions always have a constant additive rate of change. Find the rate of change for the table and the graph. 1.5 − 0.

Quadratic functions are useful for modeling problems involving area and projectile motion. In this section, you will learn how to identify, graph, and solve quadratic functions in various forms. You will also explore some real-world applications of quadratic models, such as finding the maximum height of a rocket or the minimum area of a fence.

Jessica is asked to write a quadratic equation to represent a function that goes through the point (8, -11) and has a vertex at (6, -3). Her work is shown below.-11 = a(8 - 6)2 - 3-11 = a(2)2 - 3-11 = 4a - 3-8 = 4a a = -2 After Jessica gets stuck, she asks Sally to help her finish the problem. Sally states that Jessica needs to write the quadratic equation using the value she found for a, -2 ...
