Answer:
B) One solution: x=1, y=4
Step-by-step explanation:
The number of points of intersection mark how many solutions there are. In this case, the two lines only intersect at one point, hence one solution. This point is located at (1, 4).
First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.
Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.
To find them combined, multiply:
1/2 * 1/10
1/20
0.05

Answer: It is proportional because 195/3 equals 65 and 325/5 equals 65 as well, so it is proportional.

Answer:
Step-by-step explanation:
Add 2 to both sides
Simplify
Subtract 
from both sides
Simplify
Multiply both sides by 
(reverse the inequality)
Simplify
Divide both sides by 
Divide the numbers: 
Divide the numbers: 
Apply fraction rule: 
Divide the numbers: 
Log5 x=4 logx 5
Ln x/ln5=4(ln5 / ln x) logx z=ln x / ln z
least common multiple=ln5 * ln x
ln²x=4ln²5
√(ln² x)=√(4 ln²5)
ln x=2ln 5
x=e^2ln5=25
Answer: x=25.
