Please helppp<br> solve for y
erastovalidia [21]

Answer: y=\frac{-x}{w-3}

Step-by-step explanation:

To solve for y, we want to isolate y.

w=\frac{3y-x}{y}             [multiply both sides by y]

yw=3y-x         [subtract both sides by 3y]

yw-3y=-x      [factor out y]

y(w-3)=-x     [divide both sides by (w-3)]

y=\frac{-x}{w-3}

Now, we know that y=\frac{-x}{w-3}.

What is the missing constant term in the perfect square that starts with x^2-20xx 2 −20xx, squared, minus, 20, x ?
tangare [24]

Answer:

Missing constant: 100

Step-by-step explanation:

perfect square  (a - b)^2 = a^2 - 2ab + b^2

In this case

20x = 2 * x * 10

and

10^2 = 100

so

(x - 10)^2 = x^2 - 20x + 100
