Exploring STAAR Algebra 1 EOC Released Exam Questions 11-15

The video tutorial covers problems 11 to 15 from a released Algebra 1 exam. It begins with solving problem 11 using a calculator to find the correct answer from a table of values. Problem 12 involves calculating the volume of a rectangular prism using a formula. Problem 13 focuses on graphing and understanding the slope of a line. Problem 14 requires calculating the pay difference between senior and junior employees. Finally, problem 15 discusses the concepts of independent and dependent variables in the context of burning calories over time.

What is the first step in solving problem 11 using a calculator?

• Input the entire equation and solve for x

• Convert the equation to a simpler form

• Cross out incorrect options based on the table

• Use the 'second graph' function to find a table of values

What does plugging in 5 into the equation in problem 11 yield?
