Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
<u>Define:</u>
Let the number of messages Dale sent= x
The number of messages Yolanda sent = x + 6
The number of messages Tony sent = 3(x + 6)
<u>Equation:</u>
x + (x + 6) + 3(x + 6) = 114
x = 19
<u>Answer:</u>
Dale = 19
Yolanda = 25
Tony = 75
Answer:
B.) You think about how your choice of narrator will affect the story before you begin writing, should be the most correct choice given. I hope this helps.
Given:
The inequalities are:
or
To find:
The solution for the given inequalities and graph the solution.
Solution:
We have,
or
Solve the above inequalities separately.
Divide both sides by -5.
...(i)
And,
Divide both sides by 2.
...(ii)
From (i) and (ii). we get
or
The interval notation of the solution is .
The graph of the solution is shown below.
Number 1 is 6 number two is -8 and number three is -10
