What is the constant of proportionality in the equation y =2.5xy=2.5 xy

2.5

Step-by-step explanation:

We know that the constant of proportionality is the ratio between two directly proportional quantities.

The equation of direct variation between two quantities x and y is given by :-

, where k is the constant of proportionality,

The given equation : -

When we compare to the general direct variation equation , we get

hence, the constant of proportionality in the equation  2.5

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

i pretty sure it is
