GrogVix [38]

Answer:

(2x-3)(-3+2x),(16-x^2)(x²-16),4y^2+25)(25+4y^2)

Step-by-step explanation:

I know that the rest of the products didn't make a perfect square cause they don´t aren´t squared,I also know that they are the odd ones out among the rest of the product so yeah,I am not too sure if I got it right...sorry if I didn´t.

the time (y) that it takes a machine to produce a batch of items is directly proportional to the number of items in the batch (x
mars1129 [50]

ANSWER

A. y=3.4x

EXPLANATION

It was given that, the time (y) is directly proportional to the number of items (x).

We can write this mathematically as:

y \propto \: x

If we introduce the constant of proportionality, we obtain;

y = kx

If y=17 and x=5, then,

17 = 5k

k = 3.4

Hence the equation that models the situation is;

y = 3.4x
