Answer: -48
Step-by-step explanation:
When your subtracting negatives you go farther from zero. When you add negatives still go farther from zero but, when you have a negative number with a positive number it will be a 50% chance you'll get a positive number.
For example: -2 - (-5) = -7
Example 2: -10 + 20 = -10
How? 20 is more than -10 therefore when you count 20 from -10 u get 10.
Answer:
48√7
Step-by-step explanation:
Start with f(x) = (x-9)/(x+5) and g(x) = (-5x-9)/(x-1). To obtain f(g(x)), throw out each appearance of x in f(x) = (x-9)/(x+5) and replace it with <span>g(x) = (-5x-9)/(x-1):
f(g(x)) = [</span>(-5x-9)/(x-1) - 9] / [<span>(-5x-9)/(x-1) + 5]
Now simplify the algebra. If your result equals just x, then you have proven that f and g are inverses of one another. Need help with the fractions? If so, do what you can and share it here; I'd then be glad to give you feedback on your work.</span>
