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]
fill in the blank 3(2+7a)=6+
Answer:
[tex]3(2+7a)=6+[/tex]
[tex]6 + 21a = 6[/tex]
[tex]21a + 6 = 6 + 21a[/tex]
answer is 21a
Data collected for 300 fish for north atlantic. The length of the fish (in cm) is summarized in the histogram below.
Answer:
The lower class limit of the first class is 40
Step-by-step explanation:
Given
See attachment for histogram
Required
The lower limit of the first class
The attached histogram has overlapping interval, and the intervals are:
40 to 60, 60 to 80, 80 to 100, and so on....

what is the cube root of 8
Answer:
its 2
Step-by-step explanation:
because 2*2*2 is 8
The scatter plot suggests a relationship between time and the distance from the destination. The equation of the line of best fit is y=-0.6x+15, and the correlation coefficient is -0.8. Which best describes the correlation between the two variables?
a. weak positive
b. strong positive
c. weak negative
d. strong negative
Answer:
Strong Negative
Step-by-step explanation:
We already know that the answer is between c and d because the correlation coefficient negative.
We just have to figure out whether it is strong or weak.
In general, anything between -.7 and -1 is considered to have a strong correlation. -.8 is in between -.7 and -1 therefore the correlation is best described as strong negative.
What is the solution to the inequality? 2x-5<17
Answer:
[tex]x<11[/tex]
Step-by-step explanation:
Hi there!
[tex]2x-5<17[/tex]
Add 5 to both sides
[tex]2x-5+5<17+5\\2x<22[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} < \frac{22}{2} \\x<11[/tex]

Brackets go first, 5 (y) - 4 (x) = 1. Now, 3 x 1 = 3, you do this because of the 3 next to the brackets. Now add them together.
For the past week, your restaurant revenue was $28,675 and your food cost was $9,274. Calculate your gråss margi
percentage (revenue - food cost)lrevenue). Remember to round to the nearest percent.
a) 63%
b) 68%
C) 73%
d) 78%
Answer: b) 68%
Step-by-step explanation:
Gross margin is used to calculate the amount left of revenue after the costs of goods sold is accounted for.
The formula is:
= (Revenue - Cost) / Revenue
= (28,675 - 9,274) / 28,675
= 0.67658
= 68%

What are two step equations that equal 17?
Answer:
5x+7=17
Step-by-step explanation:
5x+7=17
-7 -7
----------------
5x=10
5 5
x=2
5(2)+7=17
10+7=17
17=17
The two step equations that equal 17 are:
1) 3x + 5 = 17
2) 2y - 8 = 17
The two examples of two-step equations that equal 17:
1) 3x + 5 = 17
To solve this equation, we subtract 5 from both sides:
3x + 5 - 5 = 17 - 5
3x = 12
Finally, we divide both sides by 3:
3x/3 = 12/3
x = 4
So the solution to the equation is x = 4.
2) 2y - 8 = 17
To solve this equation, we add 8 to both sides:
2y - 8 + 8 = 17 + 8
2y = 25
Next, we divide both sides by 2:
2y/2 = 25/2
y = 12.5
So, the solution to the equation is y = 12.5.
