Answer:
D. -1
Explanation:
Parallel lines will always have the same slope
Y^2 - (y+5)^2 = 20
starting with (y+5)^2 that's y^2 + 5y + 5y + 25
then you change the signs and get
y^2 - y^2 - 10y - 25 = 20
so -10y = 45 >> 10y = -45 >> y = -4,5
answer: A
Answer:
Converges
Step-by-step explanation:
g(x) = 1/eˣ = (1/e)ˣ
This is a geometric series. │1/e│< 1, so the series converges.
f(x) = 1 / (√x + eˣ), so f(x) < g(x). Therefore, if g(x) converges, then f(x) also converges.
