If you multiply 3 and 3 and 3
Answer:
A
Step-by-step explanation:
Table:
it says that x is the amount of tickets, so that would be 1, 2, 3, etc.
It says that y is the money spent and also tells us that one ticket is $3, so obviously the money would be increasing by thirds: 3, 6, 9
This all goes with the first table (table A)
Graph:
As for the graph-
X = # of tickets (1, 2, 3)
Y = $ spent (3. 6, 9)
The answer would be graph A, because when looking at it you can tell that the starting point is at $0 for 0 tickets, unlike for graph b, which shows $3 for 0 tickets, which does not make any sense. But when you continue on when graph A, you can tell that this answer choice is correct, because every time, the y value is 3 times the x value which means: y=3x
Answer:
0.08
Step-by-step explanation:
Please use parentheses to indicate which operations must be done first. I 'm choosing to believe that you meant 7^(3x-1) and 5^(x-1).
Taking the common log of both sides, we get:
(3x-1)log 7 = (x-1)log 5
Then 3x·log 7 - log 7 = x log 5 - log 5
Grouping the x terms:
x(3·log 7 - log 5) = log 7 - log 5. We combine log 7 and log 5, obtaining log (7/5).
Then x(3·log 7 - log 5) = log (7/5).
Solving for x:
log (7/5)
x = ---------------------
3·log 7 - log 5
0.1461
x = ------------- = 0.08
1.0363
This agrees with the 3rd answer choice.
A) 3.5
B) 9.8666
Hope this helps
