Y2-25=0 solve for factoring

y=5

or

y=25/2

depending on what you meant by the question

Step-by-step explanation:

Do you mean 2y, or y^2? I'll solve both ways I guess

If you meant 2y:

2y-25=0

Add 25 to the other side

2y=25

divide both sides by two

y=25/2

if you meant y squared:

y^2-25=0

add 25 to the other side

y^2=25

take the square root of both sides

y=5

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )
