18+8x=-2y
18+8x/-2=-2y/-2
-8-4x=y

To help further, this equation is in Standard Form:

Ax+By=C
8x-2y=18

Using the literal equation (the one with variables) you can simplify down into Slope-Intercept Form, y=mx+b, and you end up with this:

y=(-A/B)x+(C/B)

Therefore, you can substitute m with -A/B and b with C/B. Even though you already have the answer, I hope this helps you in future use.

Evaluate the expression (ab)2 for a = 4 and b = 3. A. 36 B. 24 C. 81 D.144

Answer:

Option D = 144

Step-by-step explanation:

First, you are not putting the expression correctly. I'm assuming you are mean to say (ab)². This is because if you want to multiply by 2, the 2 usually goes first like this 2ab. But it's not case, so, it should be as I said.

Now, let's replace the values for a and b into the expression:

(ab)² = (4 * 3)² = (12)² = (12*12) = 144

That's is why is option D.
