Remainders and Function Patterns

The video tutorial covers four math problems, each focusing on different concepts. Problem 24 involves identifying flaws in a solution procedure for an equation. Problem 25 explores pattern recognition in geometric figures, specifically the number of squares added in a sequence. Problem 26 requires determining a function from a table of values, focusing on algebraic patterns. Finally, Problem 27 involves interpreting graphs to understand remainder functions when dividing whole numbers by 10.

What is a major flaw in the procedure of solving the equation -3x + 25 = 4?

• Confusing subtraction with addition

• Using the equal sign incorrectly

• Making an arithmetic error

• Reversing the order of operations

What is the function w in terms of x and y based on the table?

• w = 8y + 5x

• w = 8x + 5y

• w = 5y + 8x
