To find the point of symmetry:
⇒ must find where the distance between the original point and the
line of symmetry and reflected point and the line of symmetry are
equally distant from each other
Based on that knowledge:
⇒ the image appears to be entirely reflected horizontally
⇒ when the line of symmetry is the y-axis
⇒ A, A' equal distant from line of symmetry
⇒ B, B' equal distant from line of symmetry
⇒ C, C' equal distant from line of symmetry

Answers
just do 1.2*number of students in 2012 to get the answer
Answer:
432 9th grade a students
Step-by-step explanation:
so In 2012 there the percentage was 11th grade 11% and 12th grade 12% and 9th grade 30% and 10th grade 47%
total is 1200
in 2014 their is 1.2*1200 students as that is adding on 20%
which is 1440
so then do 0.3*1440=432 9th grade a students as that give your 30%

An equation is formed of two equal expressions. The equation that can be used to represent the graph is y=50x+300.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) The rate of change, in this case, signifies the number of followers Zora is gaining per hour. It can be found using any two coordinates of the line.
(x₁ , y₁) = (0,300) = coordinate of point 1,
(x₂ , y₂) = (2,400) = coordinate of point 2,
Now, the rate of change or the slope will be equal to,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1} = \dfrac{400-300}{2-0} = 50[/tex]
Hence, the rate at which Zora will gain followers is 50 followers/hour.
B.) The y-intercept is the value of y when the value of x is 0. Therefore, the y-intercept of the function is 300.
The y-intercept of the graph is 300, which means at the very initial stage Zora will have 300 followers.
C.) The graph is represented by a line, and the general equation of a line is represented by y=mx+c. To know the value of the constant c, substitute the value of the slope and any coordinate in the equation.
[tex]y=mx+c\\300=50(0)+c\\c=300[/tex]
Hence, the equation that can be used to represent the graph is y=50x+300.

For a particular peculiar pair of dice, the probabilities of rolling 1, 2, 3, 4, 5, and 6 on each die are in the ratio $1:2:3:4:5:6$. What is the probability of rolling a total of 7 on the two dice
Answers
Step-by-step explanation:
$ 1: 2: 3: 4: 5: 6: 7: 7: in ratio
probability on two dice
1, 2, 3, 4, 5, 6, 7, 7.
The probability of rolling a total of 7 on the two dice is 8/63 if in the particular peculiar pair of dice, the probabilities of rolling 1, 2, 3, 4, 5, and 6 on each die are in the ratio 1:2:3:4:5:6.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Let x be the probability of rolling a 1.
Ratios are 1:2:3:4:5:6
Then,
x + 2x + 3x + 4x +5x + 6x = 1
21x = 1
x = 1/21
The possible combinations of two rolls that total 7 are:
{(1,6) ; (2,5) ; (3,4) ; (4,3) ; (5,2) ; (6,1)}
The probability P of rolling a total of $7$ on the two dice is equal to the sum of the probabilities of rolling each combination.
[tex]\rm P = \dfrac{1}{21}\cdot\dfrac{6}{21}+\dfrac{2}{21}\cdot\dfrac{5}{21}+\dfrac{3}{21}\cdot\dfrac{4}{21}+\dfrac{4}{21}\cdot\dfrac{3}{21}+\dfrac{5}{21}\cdot\dfrac{2}{21}+\dfrac{6}{21}\cdot\dfrac{1}{21}\\\\=\dfrac{8}{63}[/tex]
Thus, the probability of rolling a total of 7 on the two dice is 8/63 if in the particular peculiar pair of dice, the probabilities of rolling 1, 2, 3, 4, 5, and 6 on each die are in the ratio 1:2:3:4:5:6.

The equivalent function of f(x) = 16x^2 - 1 is f(x) = (4x + 1)(4x -1)
How to determine the equivalent function?The function is given as:
f(x) = 16x^2 - 1
Express 16 as 4^2 and 1 as 1^2
f(x) = (4x)^2 - 1^2
Apply the difference of two squares
f(x) = (4x + 1)(4x -1)
Hence, the equivalent function of f(x) = 16x^2 - 1 is f(x) = (4x + 1)(4x -1)

Mary wants to take group fitness classes at a nearby gym, but needs to start by selecting a membership plan. With the first membership plan, Mary can pay $70 per month, plus $1 for each group class she attends. Alternately, she can get the second membership plan and pay $10 per month plus $4 per class. If Mary attends a certain number of classes in a month, the two membership plans end up costing the same total amount. How many classes per month is that?

What is a Linear Equation?A linear equation can expressed in slope-intercept form, as, y = mx + b.
m = unit rate/slopeb = initial value/y-interceptLinear equation for the first membership plan:
b = 70
m = 1
x = number of classes
y = total amount
Equation for the first membership plan: y = x + 70
Linear equation for the second membership plan:
b = 10
m = 4
x = number of classes
y = total amount
Equation for the second membership plan: y = 4x + 10
The system of equations are:
y = x + 70
y = 4x + 10
The solution is the point at which the line for both equations intersect on the graph as shown in the image attached below, which is: (20, 95).

The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
How to rotate the triangle?
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
