The ordered pair (1, 12) lies on the graph of the exponential function f(x) = 3(2)2x. which is the correct answer would be option (A).
The graph of an exponential function of the form f(x) = abˣ is a curve that passes through the point (0, a), where a is the initial value of the function.
In the given equation, the initial value is 3, so the graph of f(x) passes through the point (0, 3).
To find other points on the graph of f(x), we can plug different values of x into the equation and solve for the corresponding value of y.
For example, if we plug x = 3 into the equation, we get:
f(3) = 3(2)² × 3
= 3(16)
= 48
Therefore, point (3, 48) does not lie on the graph of f(x).
Similarly, if we plug x = 1 into the equation, we get:
f(1) = 3(2)² × 1
= 3(4)
= 12
Thus, point (1, 12) lies on the graph of f(x).

13. Identify the table that does not represent a function.
Answers
The four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e : ( 2, 3 ) , ( 2, 5 ) , ( 2, 7 ).
What is Function?
Function is a relation which each member of the domain is mapped onto exactly one member of the codomain.
There are many types of functions in mathematics such as :
Linear Function → f(x) = ax + b
Quadratic Function → f(x) = ax² + bx + c
Trigonometric Function → f(x) = sin x or f(x) = cos x or f(x) = tan x
Logarithmic function → f(x) = ln x
Polynomial function → f(x) = axⁿ + bxⁿ⁻¹ + ...
If function f : x → y , then inverse function f⁻¹ : y → x
Let us now tackle the problem!
According to the definition above, it can be concluded that a function cannot have the same x value.
Of the four tables available in choices, table option D is not a function. This is because there is the same x value, x = 2 i.e :
( 2, 3 ) , ( 2, 5 ) , ( 2, 7 ).

How to Find the Inverse of a Function?Any function can be solved for by substituting one variable for another to discover the inverse of that function.
Below is an example to help you understand.
Find the inverse of h (x) = (4x + 3)/(2x + 5)
Solution
H (x) should be changed to Y.
h (x) = (4x+3)/(2x+5) y = (4x + 3)/(2x + 5)
Change the order of x and y.
⟹ x = (4y + 3)/ (2y + 5).
The following formula should be used to solve for y in the equation above:
⟹ x = (4y + 3)/ (2y + 5)
Divide both sides by (2y + 5)
⟹ x (2y + 5) = 4y + 3
Distribute the x evenly.
⟹ 2xy + 5x = 4y + 3
isolate y.
⟹ 2xy – 4y = 3 – 5x
⟹ y (2x – 4) = 3 – 5x
Divide through by 2x - 4 to obtain;
⟹ y = (3 – 5x)/ (2x – 4) (2x – 4)
Finally, swap out y for h - 1. (x).
⟹ h – 1 (x) = (3 – 5x)/ (2x – 4) (2x – 4).

Answers
The net pay of Billy after 8% taxes and 10% retirement policy is $1600.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, From Billy's salary of $2000 8% of his paycheck goes to income taxes, and 10% automatically goes into retirement.
So, To obtain a net salary of Billy we'll subtract the percentage amount of 8% and 10% from the base of $2000.
Therefore, Net pay of Billy is {2000 - (8/100)×2000 - (10/100)×2000}.

What value of P makes this equation true
2p=-3p-6/4
Answers
Answer:
The answer is p = -6/3. This is the value of p that makes the original equation true.
Step-by-step explanation:
To solve this equation, we must first isolate the variable p on one side of the equation. To do this, we can use the properties of equality to add or subtract the same value from both sides of the equation.
First, we can subtract 2p from both sides of the equation to get rid of the 2p term on the left side. This gives us 0 = -3p - 6/4.
Next, we can add 6/4 to both sides of the equation to get rid of the constant term on the right side. This gives us 6/4 = -3p.
Finally, we can multiply both sides of the equation by -4/3 to get rid of the coefficient -3 on the right side. This gives us -6/3 = p.
Therefore, the value of p that makes the equation true is p = -6/3.

The excel cable company has a monthly fee of $32 an additional charge of $8 for each premium channel. The best cable company has a monthly fee of $26 and an additional charge of $10 for each premium channel. The Horton family is deciding which of these 2 cable companies to subscribe to.
(A) For what number of premium channels will the total monthly subscription fee for the excel and best cable companies be the same?
The Horton family decides to subscribe to 2 premium channels for a period of one year.
(B) Which cable company should they subscribe to in order to spend less money, Excel or Best? Explain your reasoning.
(C) How much money will the Hortons save in one year by using the less expensive company?
Answers
The Horton family subscribes to 3 premium channels. The total monthly subscription fee for the excel cable company is 48 dollars. The Horton family will save 24 dollars in one year by using the less expensive company.
(A) To find the number of premium channels for which the total monthly subscription fee for the excel and best cable companies will be the same, we set these two expressions equal to each other and solve for x:
32 + 8x = 26 + 10x
8x - 10x = 26 - 32
-2x = -6
x = 3
Therefore, the Horton family subscribes to 3 premium channels.
(B) The total monthly subscription fee for the excel cable company is 32 + 8 × 2 = 48 dollars if the Horton family subscribes to 2 premium channels. The total monthly subscription fee for the best cable company is 26 + 10 × 2 = 46 dollars if the Horton family subscribes to 2 premium channels.
Since the total monthly subscription fee for the best cable company is less than the total monthly subscription fee for the excel cable company, the Horton family should subscribe to the best cable company in order to spend less money.
(C) If the Horton family subscribes to the best cable company for one year, they will save 48 - 46 = 2 dollars per month. Over the course of one year, they will save 2 × 12 = 24 dollars.
Therefore, the Horton family will save 24 dollars in one year by using the less expensive company.

Answer: They must mix __ Kilograms of the 20% chocolate and __ Kilograms of the 60% chocolate.
Answers
Using a system of equations to solve the problem, the candy distributor must mix 190 Kilograms of the 20% chocolate and 10 Kilograms of the 60% chocolate to create 200 Kilograms of a 22% fat-content chocolate.
What is a system of equations?A system of equations means two or more equations solved simultaneously.
They are known as simultaneous equations and can be solved graphically, by elimination, by substitution, or matrix.
The fat-content of one of the chocolate blend = 20%
The fat-content of the second chocolate blend = 60%
The expected mixture will have a fat-content = 22%
The total kilograms of the end mixture = 200 kilograms
Let the 20% fat-content chocolate = x
Let the 60% fat-content chocolate = y
x + y = 200 ... Equation 1
Solving for x, x = 200 - y
0.2x + 0.6y = 0.22(200) ... Equation 2
By substitution in Equation 2:
0.2(200 - y) + 0.6y = 44
40 - 0.2y + 0.6y = 44
40 + 0.4y = 44
0.4y = 4
y = 10
x = 200 - y
x = 190 (200 - 10)
Based on the system of equations, 190 kilograms of the 20%-fat-content chocolate must be mixed with 10 kilograms of the 60% fat-content chocolate.
