The correct option C: y = (x + 2)(x -3)²(x - 1)² is function which correctly represents the given graph.
What is defined as the graphing?A diagram that depicts the relationship between quantities, particularly one in which lines, bars, as well as proportional areas portray how a quantity depends on it or changes with the other. A curve or line depicting a mathematical function or eq, usually drawn in Cartesian coordinates.In mathematics, a graph is characterized as a pictorial representation or diagram that organizes data or values.The graph's points frequently depict the connection between two or more variables.For the given graph;
Select one coordinate of the curve from the graph.
Point (0, 18); in which y is 18 for x = 0.
Now, go by option and put the value of x = 0 and find the correct value of y.
Option C: y = (x + 2)(x -3)²(x - 1)²
Put x = 0
y = (0 + 2)(0 -3)²(0 - 1)²
y = (2)(-3)²(- 1)²
y = 18
We, get the correct coordinates (0, 18).
Thus, the correct option is C, which satisfies the given graph.

Altred is saving up money for a down payment on a house. He currently has $4739, but knows he can get a loan at a lower interest rate if he can put down $5336. If heinvests the $4739 in an account that earns 5.1 % annually, compounded monthly, how long will it take Alfred to accumulate the $5336? Round your answer to two decimal places, if necessary.
Given the word problem, we can deduce the following information:
Principal amount = $4739
Future amount = $5336
Interest = 5.1 % =0.051
To determine the time to accumulate the $5336, we use the compound interest formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]A=Future amount=$5336
P=Present amount=$4739
r=interest rate = 0.051
n=number of compounding periods =12
t=time in years
We also note that the number of compounding periods must be 12 since the investment is compounded monthly.
We plug in what we know:
[tex]\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ 5336=4739(1+\frac{0.051}{12})^{12t} \\ Simplify\text{ and rearrange} \\ 5336=4739(\frac{12.051}{12})^{12t} \\ 12t=\frac{\ln\frac{5336}{4739}}{\ln\frac{12.051}{12}} \\ t=\frac{\operatorname{\ln}\frac{5,336}{4,739}}{12\operatorname{\ln}\frac{12.051}{12}} \\ Calculate \\ t=2.33 \end{gathered}[/tex]Therefore, the answer is 2.33 years.

Answer:
The answer should be x=2.6
Step-by-step explanation:
9x-9=3x+7
-first you should move the numbers so you can get all your x values on one side and all your regular numbers on the other like this
9x-3x=7+9
-What i basically did was i passed the 3x from the right side to the left side of the equation, since in adding the 3x originaly, when i pass it to the left side itll be subtracting. then i passed my -9 to the right side of my equation, since i was subtracting originaly ill have to now switch it to adding
-after you do this you are going to want to want to combine like terms
6x=16
-then you are going to want to devide on both sides so you can get x alone
x=2.6

Which of the following statements is true about the graph shown?
The equation y = 4.5x is correctly represented by the graph.
The graph is incorrect and the line should go through the point (3, 13.5).
The graph is incorrect and the line should go through the point (4.5, 4.5).
The graph does not show a proportional relationship.
Answer:
B. The graph is incorrect and the line should go through the point (3, 13.5)
Step-by-step explanation:
The equation is y = 4.5x
y = the y-axis/dependent variable
x = the x-axis/independent variable
4.5 x 1 = 4.5
4.5 x 2 = 9
4.5 x 3 = 13.5
Therefore the written ordered pairs would look like this.
(1, 4.5)
(2, 9)
(3, 13.5)
In the graph, (3, 13.5) is graphed as (13.5, 3) making the graph incorrect.
The statement which is true about the graph shown is that: the graph is incorrect and the line should go through the point (3, 13.5).
How to interpret the graph?Generally speaking, the graph of any linear function is always modeled by a straight line and it indicates a proportional relationship because it starts from the origin (0, 0).
Mathematically, a proportional relationship can be represented or modeled by the following linear equation:
y = kx
Where:
k represents the constant of proportionality.x and y represents the data points, variables, or coordinates.At data point (4.5, 4.5), we have:
y = 4.5x
y = 4.5(4.5)
y = 20.25 (incorrect).
At data point (3, 13.5), we have:
y = 4.5x
y = 4.5(3)
y = 13.35 (correct).
Therefore, we can logically deduce that this graph is incorrect because its line didn't pass through the data point (3, 13.5).

What is defined as the system of equations?When two or more equations are solved together in algebra, the solution should satisfy all of the equations with in system. The amount of equations must equal the amount of unknowns for a system to produce a unique solution. Even so, no solution is guaranteed. If there is a solution, the system has been consistent; otherwise, it is inconsistent.For the given system of equation,
4x + 6y =24 ......eq 1
and 2x + 3y = 8 ..... eq2
use elimination method.
Multiply eq 2 with 2 and subtract from eq 1.
0 = 16
But 0 ≠ 16, the system of equation becomes untrue.
As, the values o f the variables x and y are getting cancelled. So, the there is no solution existed for the given system.
Also,the ratio of 4x/2x = 2 and 6y/3y = 2 is same thus, no solution is possible for the system.
Now, when the we triple each side of the first equation 4x+6y=24, we have 12x+18y=72.
The new system 12x+18y=72 and 2x+3y=8
Then, also 12x/2x = 6 and 18y/3y = 6 is also same. Then, also the system of equation does not have any solution of the system.

The cost of attending an amusement park is $15 for children and $35 for adults. On a particular day, the attendance at the amusement park is 25,000 attendees, and the total money earned by the park is $600,000. Use the given matrix equation to solve for the number of children’s tickets sold. Explain the steps that you took to solve this problem.
The number of children's tickets sold is 13750.
Let the number of children be x and the number of adults be y.
The total number of attendance at the amusement park is 25,000.
So we have an equation
x + y = 25000 ......(i)
The cost for children is $15 and the cost for adults is $35, and the total money earned by the park is $600,000.
So we have another equation,
15x + 35y = 600,000
3x + 7y = 120,000 ......(ii)
Multiplying equation (i) with 3 we get
3x + 3y = 75000
3x + 7y = 120,000
Now subtract both the equation we have,
4y = 45000
y = 11250
Now put the value of y in equation (i) we get
x + 11250 = 25000
x = 13750
Where x is the number of children's tickets sold.
Therefore the number of children's tickets sold is 13750.

Part A: Given the function
g(x) = |x - 5| describe the graph of the function, including the vertex, domain, and range.
Part B: If the parent function
f(x) = |x| is transformed to
h(x) = Ix| + 3, what transformation occurs from f(x) to h(x)? How are the vertex and range of h(x) affected?
Part A: The vertex, domain, and range of the function g(x) = |x-5| is
( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).
Part B: The function f(x) = |x| is vertically shifted by 3 units to get the function h(x) = |x| + 3. The y - coordinate of the vertex is shifted by 3 units.
In Part A:
The given function is;
g(x) = | x - 5 |.
Now, The x - coordinate of the vertex will be:
x - 5 = 0
x = 5
Therefore, the y- coordinate of the vertex will be:
y = g(x) = | x - 5 |
y = g(7) = | 5 - 5|
y = 0
So, The vertex of the absolute function is ( 5, 0 ).
Since, All real numbers fall under the expression's domain, with the exception of cases where it is undefined. In this case, the phrase is defined even if there is no real number.
Hence, In Interval Notation the domain is;
⇒ ( - ∞ , ∞ )
And, The set of all legitimate y values is the range.
Hence, In Interval Notation the range is:
⇒ [0, ∞ )
Now, In Part B:
Function h(x) = |x| + 3 is the transformed version of the parent function
f(x) = |x|.
For the parent function f(x) = |x|, the vertex is ( 0, 0).
Since, The range of an absolute function in the form c( | ax + b | ) + k is
f(x) ≥ k.
Therefore, The range of the function f(x) = |x| is f(x) ≥ 0 and in interval notation is [ 0, ∞ ).
For the transformed function h(x) = |x| + 3.
The vertex of the function is ( 0, 3 ).
The range of function is h(x) ≥ 3 and in interval notation is [3, ∞ ).
Hence, the y coordinate of the vertex is transformed by 3 from f (x) to h(x).
So, Part A: The vertex, domain, and range of the function g(x) = |x-7| is
( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).
Part B: The function f(x) = |x| is vertically shifted by 2 units to get the function h(x) = |x| + 3. The y coordinate of the vertex is shifted by 3 units.
