3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtrcted by 6
Answers
Answer:
x = -0.5
Step-by-step explanation:
Here we have the sentence:
"3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtracted by 6"
The first part:
"3 to the power 2x+3 is subtracted by 9..."
This can be written as:
[tex]3^{2x + 3} - 9[/tex]
"... is equal to 2 times 9 to the power x+1 and is subtracted by 6"
[tex]3^{2x + 3} - 9 = 2*9^{x + 1} - 6[/tex]
Let's solve this for x.
First, we can add 9 in both sides:
[tex]3^{2x + 3} = 2*9^{x + 1} - 6 + 9 = 2*9^{x + 1} + 3[/tex]
We also know the relations:
[tex]a^n*a^b = a^{n + b}[/tex]
and
[tex](a^n)^m = a^{n*m}[/tex]
We can write the left part as:
[tex]3^{2x + 3} = 3^{2x}*3^3 = (3^2)^x*3^3 = 9^x*27[/tex]
And the right side as:
[tex]2*9^{x + 1} + 3 = 2*9^x*9 + 3 = 18*9^x + 3[/tex]
Then the equation becomes:
[tex]27*9^x = 18*9^x + 3[/tex]
Now let's move both terms with 9^x to the left side:
[tex]27*9^x - 18*9^x = 3\\[/tex]
[tex](27 - 18)*9^x = 3[/tex]
[tex]9*9^x = 3[/tex]
[tex]9^x = 3/9 = 1/3[/tex]
Now remember that:
Ln(a^b) = b*Ln(a)
Then if we apply the Ln( ) function to both sides, we get:
[tex]Ln(9^x) = Ln(1/3)[/tex]
[tex]x*Ln(9) = Ln(1/3)[/tex]
[tex]x = \frac{Ln(1/3)}{Ln(9)} = -0.5[/tex]
anyone know this equation ????

The lowest elevation in Nevada is about 65
meters below sea level. The lowest elevation in
Florida is about 2/5the value of the lowest
elevation in Nevada. Which value best represents
the lowest elevation, in meters, in Florida?
Answers
Answer:
-26 meters
Step-by-step explanation:
first do 65/5 because it is asking how much less florida´s elevation is than nevada´s. and because it is a fraction you do it divided by 5.
65/5=13
so now because the fraction was 2/5 do 13+13
you get 26. so florida´s lowest point is -26 meters.

The same mothers responded to both questions. The results are shown in the first table.
Of the 43 mothers with 3 or more children 26 of them own a minivan.
Complete the two way frequency table to represent the correct mothers for each cell of the table.
Answers
Answer:
To draw a two way table for the own a mini van table as it says 26 own a minivan for people with 3 or more children is subtraction from the given full total 37;
37 - 26 = 11 and finding two or more children is 51- ?= ? see below ans 51- 11 = 40 for those that don't own a mini van.
Then its quick addition to find 40+17 = 57
See given answers in question already easy to answer in bold before doing the sums.
one or 2 children | 3 or more children Total
Do own a mini van 11 26 = 37
Do not own a mini van 40 17 = 57

All sides of a right triangle are different lengths.
The shortest being the leg in which is opposite to the smallest angle on the standard right triangle (30 degrees). The side with the longest length is always the hypotenuse (point a-c).
Therefore, both answer a and b are eliminated considering two sides of the triangle have equivalent lengths.

In the year 2000, the population of a city was 600,000 citizens. The population increases at a rate of 1.8% per year.
a. Create and graph a function to model the population, y , (in thousands), x years after 2000.
b. In complete sentences, interpret the relationship between the rate of change of the function and its graph.
c. Predict the population of the city in the year 2012.
In your final answer, be sure to include your model, graph, interpretation, and prediction of the function.
Answers
Answer:
a) 600,000 (1.018)ᵗ, the graph is below:
* "t" is the years. 2000 is the first year, so "t" would be 1. 2012 is the 12th year so "t" would be 12.
b) As the years go by, the population increases. The years (X), and population (Y) both increase together. The graph shows that when the years increase the population increases.
c) In 2012, which would be 12 years later, I predict the population would be around 743,232 people.
