If y varies directly as x, and y is 20 when x is 4, whats this relation?

1 answer:

Y α x

y = kx

20 = k*4

20 = 4k

20/4 = k

5 = k

k = 5

Relation is y = kx , that is y = 5x

Well $19\sqrt{ $1143.8} = 19\sqrt{1143.8}$

Simplified would be: 642.58213482

642.58213482 = 642.58 = $642.58

Answer: 642.58

Hope this helps!
