If point is the image of (3,4) if it is reflected over the y axis, then the resulting point is (-3,4) (option c)
When a point is reflected over the y-axis, its x-coordinate changes sign while the y-coordinate remains the same. In other words, if we have a point (x, y), its image after reflection over the y-axis will be (-x, y).
Let's apply this rule to the given point (3, 4). When we reflect it over the y-axis, the x-coordinate changes sign, but the y-coordinate remains the same. Therefore, the image of (3, 4) after reflection over the y-axis will be (-3, 4).
So, the correct Answer: C. (-3, 4)

Question 4 (Worth 90 points)
Given the function g(x) = 6(4)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
Part A: Find the average rate of change of each section. (4 points)
Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points)
Part 1 (or a if you prefer):
f(x) = 5^x
f(x) = 5^0 = 0
f(x) = 5^1 = 5
Use this formula to solve: f(b) - f(a)/b - a
5 - 0 / 1 - 0 = 5/1 = 5
--
f(x) = 5^2 = 25
f(x) = 5^3 = 125
125 - 25 / 3 - 2 = 100/1 = 100
Average rate of change:
Section A: 5
Section B: 100
Part 2 (or b if you prefer):
Section B is 20 times greater then A
This is because Section B is increasing in the equation. Thus, Section B is of greater value than Section A.
Hope this assists you and future students.
(a) A certain solution has a hydrogen ion concentration of 0.00000914 moles per liter. Write this number in scientific notation.
(b) A humpback whale can weigh up to ×1.1105 pounds. Write this number in standard notation.
The hydrogen ion concentration can be written in scientific notation as 9.14 x 10-6 M. The weight of a humpback whale can be written in standard notation as 11,105 pounds.
Explanation:(a) The given hydrogen ion concentration of 0.00000914 moles per liter can be written in scientific notation as 9.14 x 10-6 M. To convert the number to scientific notation, we move the decimal point to the left until there is one non-zero digit to the left of the decimal point and multiply by the corresponding power of 10.
(b) The weight of a humpback whale, which is given as ×1.1105 pounds, can be written in standard notation as 11,105 pounds. To convert from scientific notation to standard notation, we move the decimal point to the right or left by the power of 10 indicated by the exponent.

Simplify 7x + 7 + 6x - 9.
13x - 2
13x + 2
11x
Answer:
x = -2/13
Step-by-step explanation:
This is a first degree polynomial. To solve it, you need to follow these steps:
Step 1: Equate the polynomial to zero
7x + 7 + 6x - 9 = 0
Step 2: Separate all numbers that have variable "x" on one side of equality and real numbers on the other side
7x + 6x + 7-9
Note: Remember that if you are going to pass a number from side to side the equality is reversed.
Step 3: Add Both Sides
13x = -2
Step 4: Isolate the "x" Variable
x = -2/13

Ervin sells vintage cars. Every three months, he manages to sell 13 cars. Assuming he sells cars at a constant rate, what is the slope of the line that represents this relationship if time in months is along the x-axis and the number of cars sold is along the y-axis?
Answer: [tex]4.33\text{ cars per month.}[/tex]
Step-by-step explanation:
Given : Ervin sells vintage cars. Every three months, he manages to sell 13 cars.
[tex]m=\dfrac{\text{change in y}}{\text{change in x}}[/tex]
If time in months is along the x-axis and the number of cars sold is along the y-axis
Change in months : 3
Change number of cars : 13
The slope of the line that represents this relationship will be :-
[tex]m=\dfrac{\text{Change in cars}}{\text{Change in months}}\\\\=\dfrac{13}{3}=4.33333\approx4.33\text{ cars per month.}[/tex]
Hence, the slope of the line = [tex]4.33\text{ cars per month.}[/tex]

How do you write 180% as a fraction or mixed number in simplest form?
To write 180% as a fraction or mixed number in simplest form, convert the percent to a fraction with a denominator of 100 and simplify the fraction. The simplified fraction is 9/5 or the mixed number is 1 and 4/5.
Explanation:To convert a percent to a fraction or mixed number in simplest form, we need to write the percent as a fraction with a denominator of 100 and then simplify it. In this case, 180% can be written as 180/100. To simplify, we divide both the numerator and denominator by their greatest common divisor, which is 20. So, the simplified fraction is 9/5. This fraction can also be expressed as a mixed number by dividing the numerator by the denominator. Since 9 is greater than 5, the mixed number is 1 and 4/5.

A) a-b=1
B) -b+c=1
C) a+b+c=1
D) a-b+c=1
Please help ;(
The correct option will be "option D".
It is given that in the x-y plane, parabola with equation y=ax² + bx + c , passes through point (-1,1).
We have to check which equation is most suitable.
What is parabola ?
The graph of a quadratic equation in two variables (y=ax² + bx + c) is called a parabola.
Parabola has the equation ,
y = ax² + bx + c --------- Equation (1)
At point (−1, 1)
x = -1 and y = 1
Substitute the values of x and y in the equation (1).
i.e., y = ax² + bx + c
1 = a × (-1)² + b× (-1) + c
1 = a × (1) - b + c
1 = a - b + c
Thus, in x-y plane at point (1,-1) , equation will be , a - b + c = 1.

A total of 210 people attended the opening night of a school musical. Student tickets cost $3.00 each while general admission tickets cost $7.50 each. If total sales were $1296, how many general admission tickets were sold?
To determine the number of general admission tickets sold, two equations were formed using the total number of attendees and total sales. By applying the elimination method to solve the system of equations, it was found that 148 general admission tickets were sold.
To solve this problem, we can set up two equations based on the number of people and the total sales. Let x represent the number of student tickets sold at $3.00 each, and let y represent the number of general admission tickets sold at $7.50 each. We are given that a total of 210 people attended, so:
1) x + y = 210
We are also given that the total sales were $1296, so:
2) 3x + 7.5y = 1296
We can solve this system of equations using the substitution or elimination method. For this example, I will use the elimination method. To eliminate one variable, we can multiply the first equation by 3, which gives us:
3x + 3y = 630
Now, by subtracting this new equation from the second equation, we eliminate x:
7.5y - 3y = 1296 - 630
4.5y = 666
Dividing both sides by 4.5, we find that:
y = 148
So, 148 general admission tickets were sold on the opening night of the school musical.
