Introduction

When it comes to maintaining a comfortable temperature in our homes, it's essential to understand how to set the thermostat to achieve the desired level of warmth or coolness. In this article, we will delve into the world of absolute value equations and explore how to solve them to determine the minimum and maximum temperatures in a house.

What is an Absolute Value Equation?

An absolute value equation is a mathematical expression that involves the absolute value of a variable or expression. The absolute value of a number is its distance from zero on the number line, without considering direction. In other words, it's the magnitude of the number, regardless of whether it's positive or negative.

The Equation $|x-72.5|=1$

The given equation is $|x-72.5|=1$ . This equation states that the absolute value of the difference between $x$ and $72.5$ is equal to $1$ . To solve this equation, we need to consider two cases:

Case 1: $x-72.5=1$

In this case, we can add $72.5$ to both sides of the equation to isolate $x$ . This gives us:

$x-72.5+72.5=1+72.5$

Simplifying the equation, we get:

$x=73.5$

Case 2: $x-72.5=-1$

In this case, we can add $72.5$ to both sides of the equation to isolate $x$ . This gives us:

$x-72.5+72.5=-1+72.5$

Simplifying the equation, we get:

$x=71.5$

The Minimum and Maximum Temperatures

Now that we have solved the equation, we can determine the minimum and maximum temperatures in the house. The minimum temperature is $71.5^{\circ} F$ , and the maximum temperature is $73.5^{\circ} F$ .

Conclusion

In conclusion, solving absolute value equations can help us determine the minimum and maximum temperatures in a house. By considering two cases and isolating the variable, we can find the solution to the equation $|x-72.5|=1$ . The minimum temperature is $71.5^{\circ} F$ , and the maximum temperature is $73.5^{\circ} F$ .

Discussion

The given options are A. 7257 and 7659 and B. $685^{\circ} F$ . However, the correct solution is $71.5^{\circ} F$ and $73.5^{\circ} F$ , which does not match any of the given options. Therefore, the correct answer is not among the given options.

Additional Tips and Tricks

When solving absolute value equations, it's essential to consider two cases: one where the expression inside the absolute value is positive, and one where it's negative. By isolating the variable and simplifying the equation, we can find the solution to the equation.

Common Mistakes to Avoid

When solving absolute value equations, it's common to make mistakes such as:

Not considering both cases
Not isolating the variable
Not simplifying the equation

To avoid these mistakes, make sure to carefully read the equation and consider both cases. Isolate the variable and simplify the equation to find the solution.
