10ax - 5ay + 2bx - by
=10ax + 2bx - 5ay - by
=2x(5a + b ) - y(5a + b )
=(2x - y )(5a +b)
-2.7 because -3.9 plus 1.2 is -2.7
N(20/100)(20/100)=20
n(1/5)(1/5)=20
n/25=20
n=500
Answer:
f(x) = 2x / (x - 1)
Step-by-step explanation:
One such function would be:
2x
f(x) = -----------
x - 1
f(x) is undefined at x = 1, so has a vertical asymptote at x = 1.
As x increases without bound, f(x) approaches (2x) / (x), or just 2. Thus, f(x) has the horiz. asy. y = 2.
