Rearrange the equation so w is the independent variable.

−2u+6w=9

Step-by-step explanation:

we have

Solve for u

That means ------> isolate the variable u (dependent variable)

Subtract 6w both sides

Divide by -2 both sides

u = -9/2 + 3w

Step-by-step explanation:

Hi, An Independent Variable in an Equation is a variable that may have its value freely chosen without considering values of any other variable. Is also known as the input value of a function.

So, to rearrange we have to isolate u:

-2u+6w=9

-2u =9 -6w

2u = -9 +6w

u= (-9 +6w)/2

u = -9/2 + 3w

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
