PLSSS NEED TO PASS LOL What is the value of x? Show your work.

4x-4=20

or, 4x=20+4

or,4x=24

or,x=20/4

tgerefore,x=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

y=mx+b

step-by-step explanation:

m slope, b y-intercept
