Desmos Tips for SAT Math: Single Variable Equations
The Digital SAT(DSAT) provides access to Desmos, a powerful graphing calculator tool, built into the SAT test app. If you’re familiar with how to use Desmos tips for SAT math, particularly for solving single-variable equations, you’ll significantly improve your accuracy and efficiency. Desmos can be a valuable tool in quickly identifying solutions, allowing you to focus more on strategy and problem-solving during the test.
For a more in-depth look at how to use Desmos effectively for SAT math, especially for solving single-variable equations, watch the video below. This tutorial covers key strategies, step-by-step examples, and helpful tips to boost your SAT math performance.
However, it’s important to emphasize that Desmos is not a substitute for strong math skills. The creators of the SAT are aware of Desmos’ functionality, which is why many test questions cannot be solved using Desmos alone. If you aim to score 650+ on the SAT math section, solid algebra skills and a thorough understanding of the SAT curriculum are essential. Desmos can help with specific tasks, but your understanding of the underlying concepts will make the most difference in achieving your desired score.
In this blog post, we’ll demonstrate how to use Desmos for SAT math to solve single-variable equations effectively and accurately. Stay tuned for future posts covering Desmos tips for more question types. We will break down the process step-by-step so that you can fully leverage Desmos to enhance your SAT math performance.
Single Variable Equations
How to Recognize Single-Variable Equations
A single-variable equation is an equation that contains only one variable. This does not include expressions, which are mathematical statements without equals signs.
Here are some examples of single-variable equations:
- What is the smallest solution to the given equation?
- What is one possible solution to the given equation?
- What is the positive solution to the given equation?
- What is the sum of the solution to the given equation?
Each of the equations shown above contains only one variable, which makes them single-variable equations.
How to Solve Single-Variable Equations in Desmos
- Enter the single-variable equation into row one of the expression list in Desmos.
- Observe the graph: Desmos will generate vertical lines where the solutions to the equation exist.
- Interpret the results: The vertical lines indicate the solutions to the equation.
Example Problem
Problem: Using desmos solve this equation:
After entering the equation into Desmos, this is what the graph will show:
This graph contains vertical lines at x = -3 and x = 10. This means that x = -3 and x = 10 are the solutions to the equation.
To explore more examples and gain deeper insights, be sure to watch the video above. It offers valuable Desmos tips tailored for the SAT.
Key Takeaways
- Desmos is a valuable tool for solving equations on the DSAT.
- Single-variable equations can be solved quickly by identifying where vertical lines appear on the Desmos graph.
- While Desmos can help with many problems, you’ll need strong math skills to tackle more complex questions.
