Q. An inverse variation includes the points (4,1) and (2,n). Find n. Write and solve an inverse variation equation to find the answer.n=_____
Understand Inverse Variation: Understand the concept of inverse variation.In an inverse variation, the product of the two variables is constant. This means if y varies inversely with x, then xy=k for some constant k.
Find Constant k: Use the given point (4,1) to find the constant k. Substitute x=4 and y=1 into the inverse variation equation xy=k. 4×1=kk=4
Use Point (4,1): Use the constant k to find n when x=2.We know that k=4 and the inverse variation equation is xy=k. Substitute k=4 and x=2 into the equation to find n.2⋅n=4
Find n for x=2: Solve for n.Divide both sides of the equation by 2 to isolate n.n=24n=2
