Respuesta :

Answer:

The correct option in both cases is None of these

Step-by-step explanation:

(1.5x , 1.5y)

means we had (x,y) before

we only had to multiply each of the two by 1.5

So the percentage enlargement will be;

(1.5x-x)/x * 100

= 0.5x/x * 100

= 0.5 * 100 = 50%

The answer is none of these

for the second one, we have

(0.7x-x)/x * 100%

= -0.3x/x * 100%

= -30%

This is a 30% reduction

The answer here too is none of these
