Answer: First off, what answer are you looking for? it's hard for me to answer something without specification.
Step-by-step explanation:
8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
Answer and Step-by-step explanation:
The signs didn't really "swap". Instead, the whole function was divided by -1, or we could say the function was divided by -3. That would turn:
-18x² - 15x + 3 = 0
into
(-18 / -3)x² - (15 / -3)x + (3 / -3) = 0
6x² + 5x - 1 = 0
And that gives the "swapped signs".
