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>
Square root of 1001=10.0033
square root of 1000=10
so 10.0033-10=0.0033
1/10=0.1
so, 1/10 is bigger than square root of 1001- square root of 1000
Answer:
42000
Step-by-step explanation:
First of all, we need to find 20 percent of 35000.
35000×20 / 100 = 7000
now we increase the bed cost by 20 percent.
35000 + 7000 = 42000
Answer:
x(x-5)(x-8)
or
x=5
x=8
Step-by-step explanation:
x(x^2-13x+40)
x(x-5) (x-8)
The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!
