Now, we can just multiply it and obtain the result

I used law presented on this example
The answer is -8
I found my answer by using desmos. It is the best app for graphing. I wrote the equation and then I looked for the point 18 on the y axis and then I looked where it was on the x axis
that is how I found my answer.
Answer:

Answer:
subtraction property
Step-by-step explanation:
because you subtracted 12x from 16x to get 4x+5=-6
This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents. When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1.
