What is the exact solution to the equation 2x 2=52x?

x = 0 OR x = 26

Step-by-step explanation:

i'm going to assume that second 2 on the left side of the equation is supposed to be an exponent?

start by getting the x term on only one side:

2x^2=52x

2x^2-52x = 0

factor:

2x (x - 26) = 0

according to the zero factor principle (ab = 0 means a=0 or b=0):

x=0 or x-26=0

final answers: x = 0 or x = 26

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
