When x = 2, y = 50 and when x = 4, y = 100. which direct variation equation can be used to model this function?

xy = 100
xy = 400
y = 25x
y = 100x

The answer is y=25x

bc 25x2=50 and 25x4=100

b

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
