Key Concepts

These are the key concepts you need to understand to accurately answer the question.

solving equations

When solving equations, the goal is to find the value of the variable that makes the equation true. Let's break down the process:


  • Understand the Equation: First, carefully examine the given equation. Notice both sides and identify all components, like exponents or roots.

  • Step-by-Step Approach: Solve the equation step by step, performing one operation at a time. This ensures you don't miss any details or make mistakes.

  • Maintain Balance: Always remember to perform the same operation on both sides of the equation to maintain balance. This is crucial for accurate solutions.

exponents

Exponents indicate how many times a number (the base) is multiplied by itself. In our example, we encounter a fractional exponent:


  • Fractional Exponents: The expression \( (1-2m)^{-5/3} \) features a fractional exponent, where -5/3 means taking the cube root and raising to the power -5.

  • Influence of Negative Exponents: A negative exponent indicates taking the reciprocal of the base. For instance, \( a^{-n} = \frac{1}{a^n} \).

  • Simplifying Exponents: To solve equations with exponents, you often need to re-write them, simplify, and isolate the variable by removing exponents through reciprocal operations.

simplifying expressions

Simplifying expressions is about making them easier to work with. Here’s a guide on simplifying:


  • Combining Like Terms: Combine terms that have the same variables to simplify the expression.

  • Reduction: Reduce fractions, exponents, and radicals to their simplest forms.

  • Example: When solving \( (1-2m)^{-5/3} = -\frac{1}{32} \), approach simplification by raising both sides to the power that cancels the initial exponent, resulting in: \( (1-2m) = (-\frac{1}{32})^{3/5} \).

isolating variables

Isolating variables means getting the variable alone on one side of the equation:


  • Operations: Use addition, subtraction, multiplication, or division to isolate the variable step by step. Each operation must be done on both sides of the equation.

  • Example: For \( 1-2m = value \), subtract 1 from both sides, then divide by -2 to solve for m.

  • Final Check: Always substitute back the value of the variable into the original equation to verify the solution is correct.

Booming Business When Computer Recyclers opened its doors, business started booming. After a few months, there was a temporary slowdown in sales, after which sales took off again. We can model sales for this business with the function $$N=8 t^{3}-133 t^{2}+653 t$$ where \(N\) is the number of computers sold in month \(t(t=0\) corresponds to the opening of the business). a. Use a graphing calculator to estimate the month in which the temporary slowdown was the worst. b. What percentage drop in sales occurred at the bottom of the slowdown compared to the previous high point in sales?
