Question

Help please variations questions

Answer 1

Explanation:

first graph

height=constant* width ( direct variation describes a linear relation between 2 variable )

6=8x ⇒ x=6/8=0.75

h=0.75w

constant is 0.75

second graph:

height=constant/width ( inverse variation)

15=x/4 ⇒x=4*15 ⇒x=60

constant=60

For two quantities with inverse variation, as one quantity increases, the other quantity decreases. k(constant)=xy
