Challenge Problems
Push your limits with advanced challenges
A recipe calls for 2 cups of flour and 3 cups of sugar. If your budget allows for a linear relationship of total cost as \(C(x) = 5x + 10\) where \(x\) is the number of batches, how will the total cost change with additional batches?
💡 Hint: Consider how each added batch impacts the overall cost in a linear manner.
If two lines are given by their equations \(y = 3x + 4\) and \(y = -\frac{1}{3}x + 2\), determine if they are parallel, perpendicular, or neither.
💡 Hint: Calculate the slopes and check the relationship.
