Number of Years Since 2009
Based on this information, which function best models the number of game consoles sold in
millions x years since 2009?
A 9(x) = 0.6(25.5)
09(x) = 25.5(0.6)
c g(x) - 6.12(25.5)
D 9(x) = 25.516 Y
The graph is an illustration of an exponential function
The equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]
How to determine the equation of the graphFrom the graph, we have the following ordered pairs
(x,y) = (0, 25.5), (1, 15.3) and (2, 9.18)
An exponential function is represented as:
[tex]y = ab^x[/tex]
When x = 0, we have:
[tex]25.5 = ab^0[/tex]
[tex]a = 25.5[/tex]
When x = 1, we have:
[tex]15.3 = ab^1[/tex]
[tex]15.3 = ab[/tex]
Substitute 25.5 for a
[tex]15.3 = 25.5b\\[/tex]
Solve for b
[tex]b = 0.6[/tex]
So, the exponential equation is:
[tex]y = 25.5 * 0.6^x[/tex]
Hence, the exponential equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]

g(x) =25.5(0.6)ˣ function best models the number of game consoles sold in millions x years since 2009?
From the given graph we can observe three ordered pairs which are (0, 25.5), (1, 15.3) and (2, 9.18).
We have to find the function which best models the number of game consoles sold in millions x years since 2009.
This we can find by using exponential function.
y=abˣ
When x = 0, we have:
a=25.5
When x=1, then y should be 15.3
15.3=ab
Substitute 25.5 for a
15.3=25.5b
Divide both sides by 25.5:
b=0.6
So the function is g(x)=25.5(0.6)ˣ

This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.
The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.

Answer:
f = 2.75p
Step-by-step explanation:
You can see that the amount of flour for 6 cakes is double the amount for 3 cakes, so the amount of flour is proportional to the number of cakes. An equation for a proportional relationship will have the form ...
f = kp
We can find the value of k from any column in the table.
8.25 = k(3) . . . . using the values in the first column
8.25/3 = k = 2.75 . . . . . divide by 3
The equation is ...
f = 2.75p

Additional comment
If the input doubles, but the output does not, then the relationship is not proportional. We ordinarily expect recipes to have proportional relationships.

investment after 20 years equals 130000. original investment was 50000. What was the interest rate?
Step-by-step explanation:
The formula states that
S. I=P*R*T/100
R=S. I*100/P*T
Simple Interest= Amount - principal
Simple Interest = 130000 - 50000
Simple Interest = 80000
R= 80000*100/50000*20
R= 800000/100000
R=8%

how can i solve -8/x-11=-2?
Answer:
See below
Step-by-step explanation:
-8/x - 11 = -2
First add 11 to both sides
-8/x - 11 + 11 = -2 + 11 simplifies to -8/x = 9
Now multiply both side by x
( -8/x) X ( x ) = ( 9 ) X ( x ) which simplifies to -8 = 9x
Divide each side by 9
-8/9 = (9x)/9 which simplifies to -8/9 = x or x = - 8/9

5x + 3y = 14
Answer: (-2, 8)
Explanation:
Plug x = -2 into the second equation. Isolate y.
5x+3y = 14
5(-2)+3y = 14
-10+3y = 14
3y = 14+10
3y = 24
y = 24/3
y = 8
We have x = -2 lead to y = 8.
Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.

Rita makes and sells necklaces. The materials to make each necklace cost $2. 75. Last week she made 8 necklaces and wants to make a total profit of $78. Using the equation 8 (x 2. 75) = 78, Rita determined that she needs to sell each necklace for $7 to make a total profit of $78. Which error did Rita make? Although she has the correct equation, she needs to sell each necklace for $12. 50. Although she has the correct solution, she should have used the equation 8 (x minus 2. 75) = 78. The equation should be 8 (x minus 2. 75) = 78, and she needs to sell each necklace for $12. 50. The equation should be StartFraction 1 over 8 EndFraction (x minus 2. 75) = 78, and she needs to sell each necklace for $75. 25.
Profit function gives the profit earned for given input. Thus, Rita has correct solution, that is, she needs to make 7 necklace to get $78 profit.
How to find the value of unknown variable in a linear equation?It might not be always possible. But for simple cases, we can try using addition or subtraction or such operations in linear equations if there is single variable with single equation.
For the given case, the profit $78 for x necklace manufactured is
[tex]8(x + 2.75) = 78[/tex]
(remember that many times, when using letters or symbols, we hide multiplication and write two things which are multiplied, close to each other. As in [tex]2 \times (x + 3) = 2(x + 3)[/tex])
Solving this equation, we get:
[tex]8(x + 2.75) = 78\\\\\text{Dividing by 8 on both the sides}\\\\(x + 2.75) = \dfrac{78}{8} = 9.75\\\\\text{Subtracting 2.75 from both the sides}\\\\x = 9.75 - 2.75 = 7[/tex]
Rita has correct solution, that is, she needs to make 7 necklace to get $78 profit.

Are the two triangles similar? Why or why not?
Answer:
(c) Similar by AA~
Step-by-step explanation:
The outside segments are marked parallel, so the angles formed where the transversals meet them are congruent. That is ∠CBD ≅ ∠EDB, and ∠CED ≅ ∠ECB. (The vertical angles where the lines cross are congruent, as well.)
So, the angles in one triangle are congruent to the angles in the other triangle. The triangles are similar by the AA~ postulate.
