It is night where I am. I am doing great as well. Good night.

I am pretty sure it is 25.

5 * 5 = 25.

Well, let's look at the equation.

We have -3(y-1) = 9.

Divide both sides by -3 and get y-1 = -3.

Add 1 to both sides to get y= -2.

Now we have to find the value of (1/2)*y.

We know y is -2, so -2*(1/2) = -1

The answer is -1.

Oreo?

Oreo!

It simplifies to (a^2)/xy

Sorry Alan.

Hey...I was wrong. (Again.)

Sorry Boseok.

To put it simply, in linear equations, if an equation is y= (any real number), then it is horizontal. For example, y=2 is horizontal, and it has an undefined slope. x=3 is actually a vertical line. Its slope is 0.

Correct me if I'm wrong.

y=-2.

Because the line is horizontal, the slope is undefined.

Thanks, Melody.

Oops, sorry. On my computer screen, it came out as ^ for some reason. I had to reload the page a couple of times.

Sorry.

I think that is an exponent sign

Ex: 2^2 is 2 to the power of 2.

Oh...it's a V?

I thought it was a root sign.

Anyway, if it was meant to be a root sign, then the answer would be 1/144 because there are no brackets.

If there were brackets - sqrt(1/144) - then the answer would be 1/12.

It is -0.0714285714285714.
