Question

X=2/5y +3 how does y change when X increases from 1 to 2
​

Answer 1

Answer:

Y also doubles

Step-by-step explanation:

$x = \frac{2}{5y} + 3$

When x=1

$1 = \frac{2}{5y} + 3 \\ \frac{2}{5y} = - 2 \\ y = \frac{ - 1}{5}$

When x=2

$2 = \frac{2}{5y} + 3 \\ \frac{2}{5y } = - 1 \\ y = \frac{ - 2}{5}$
