Determine whether the ratios 2 over 5 and 20 over 50 are proportional.

They are proportional

Step-by-step explanation:

Solve by cross multiplication :)

Since we have 2/5 & 20/50, we multiply 2 by 50 and 5 by 20.

2 ✕ 50 = 100

5 ✕ 20 = 100

I hope this helped!

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
