Which Graph Shows the Solution of 9-C 2 Or-3 C15?

In mathematics, graphs are a visual representation of data and relationships between different variables. They are used to present information in a clear and concise manner, making it easier for us to understand complex concepts. When it comes to solving equations, graphs can be particularly useful in illustrating the solutions.

In this article, we will explore the equation 9-C 2 Or-3 C15 and analyze which graph represents its solution. We will also provide a comprehensive FAQ section to address common queries regarding this equation.

Understanding the Equation 9-C 2 Or-3 C15:

The given equation, 9-C 2 Or-3 C15, may seem a bit unfamiliar at first glance. However, we can break it down to understand its components.

The expression “9-C” represents the difference between 9 and C. This means that we subtract the value of C from 9.

On the other hand, “2 Or-3 C15” is a more complex expression. The term “2 Or” implies that we have two different possibilities for the equation. The “3 C15” is a product of 3 and C15.

Considering these components, the equation can be rewritten as 9-C = 2 or 9-C = -3 C15.

Analyzing the Solutions:

To determine which graph represents the solution of this equation, we need to solve it first. Let’s solve each possibility separately and observe the resulting graphs.

1. Solving 9-C = 2:

To solve this equation, we aim to find the value of C that satisfies the equation. By subtracting 9 from both sides, we get -C = -7. Multiplying both sides by -1, we find that C = 7.

Now, let’s plot this solution on a graph. We represent the value of C on the x-axis and the value of the equation (9-C) on the y-axis. The graph will have a single point at (7, 2), indicating that C = 7 satisfies the equation.

2. Solving 9-C = -3 C15:

To solve this equation, we need to simplify it. By expanding -3 C15, we obtain -3C^15. Now, let’s bring all terms to one side to form a quadratic equation. Rearranging the equation, we have 3C^15 – C – 9 = 0.

Solving this quadratic equation may require advanced mathematical techniques such as factoring, completing the square, or using the quadratic formula. The resulting values of C will be the solutions to this equation.

Once we have the solutions, we can plot them on a graph similar to the previous case. Each solution will be represented by a point on the graph.
