If you are an Algebra 2 or Pre-Calculus teacher, you know the moment when students finally master Direct and Inverse variation... and then you throw "Joint" and "Combined" into the mix. That’s when things get tricky.
), and inversely with the number of open filtration valves ( Step 1: Find the Constant. At a temperature of and a volume of valves open, the pressure is Step 2: Solve the Mission. If the temperature rises to , the volume increases to , and you open valves, what will the new pressure be? Quick Reference for Solving For any problem on this "worksheet," follow these steps: Write the general equation: joint and combined variation worksheet kuta
( y ) varies directly as ( x ) and inversely as the square of ( z ). ( y = 12 ) when ( x = 8 ) and ( z = 2 ). Find ( y ) when ( x = 5 ) and ( z = 4 ). Mastering Joint and Combined Variation: How to Use
)Use the first set of numbers the problem gives you to find the constant of variation, Example: If varies jointly as Equation: Formula: ( y = kx ) As (x) increases, (y) increases
