Answer:
- 1/2 or - 1.5
Step-by-step explanation:
I would suggest using a table
x y
2 -1
0 0
from -1 to 0, you add 1
from 2 to 0, u subtract 2
so y/x
1/-2
Your slope will be -1/2 or -1.5
Hope this helped!
Exponential decay is the answer
Your answer is 4/5, which is 80% or 0.8
If there are 20 marbles in total in the bag, and 4 blue ones, that means that the probability of taking a blue one is 4/20.
This means that the probability of not taking a blue one is 1 - 4/20, or 20/20 - 4/20, which equals 16/20 = 4/5
I hope this helps! Let me know if you have any questions :)
Answer:
1) x=0.465
2) option A.
Step-by-step explanation:
1) The given equation is:
We rewrite this as logarithm to get:

The change of base formula is:

We apply the change of base formula on the RHS to get:



Group similar terms:

2)
From the graph, the logarithmic function approaches negative infinity as x approaches -6.
Therefore the vertical asymptote is x=-6
The graph touches the x-axis at x=-5, therefore the x-intercept is x=-5.
The correct answer is A.
