Does anyone know how this works or the answer to this?

The two square pyramids are similar. find the total volume of both pyramids if the ratio of their surface areas is 9/16

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
