How to find the point of intersection between the lines?The graph represents the given parameter
On the graph, we can see that there are two lines with the following properties:
Line 1: A slant line that extends indefinitelyLine 2: A vertical line that extends indefinitelyLine 3: A horizontal line that extends indefinitelyThe above properties means that:
Line 1: Has a defined slope i.e. the line ALine 2: Has an undefined slopeLine 3: Has a slope of 0From the graph, we can see that the lines A and the other line meet at a point
The point where these lines meet is referred to as the point of intersection

Mr. rivas bought 12 tickets to the high school drama production and spent $40. he purchased a combination of child tickets for $2 each & adult tickets for $6 each, write a system of equations to determine the number of child’s tickets (x) and adult tickets (y) he bought , the solve this system using any method you’d like.
Answer:
x = 8, y = 4
This can also be written as an ordered pair: (8, 4)
Step-by-step explanation:
First, set up a system of equations:
x + y = 12, $2x + $6y = $40
The first equation shows that there are a total of 12 tickets, and the other shows that the total of money for all the tickets adds to $40.
Then, solve by elimination by subtracting twice the first equation from the second to isolate y:
2x + 6y = 40
- (2x + 2y = 24)
0 + 4y = 16
And now we can solve for y:
4y = 16
y = 4
Then, put this back into the original equation to solve for x:
x + y = 12
x + 4 = 12
x = 8

Kate paid 2.50 for 8 juice boxes how much should kate be expected to pay for 24 juice boxes
====================================================
Work Shown:
(2.50 dollars)/(8 juice boxes) = (x dollars)/(24 juice boxes)
2.50/8 = x/24
2.50*24 = 8x
60 = 8x
8x = 60
x = 60/8
x = 7.50
----------------
Another approach:
She paid $2.50 for 8 juice boxes. The unit price is 2.50/8 = 0.3125 dollars per juice box. Multiply this by 24 to get 24*0.3125 = 7.50
----------------
Yet another method:
We know the cost for 8 juice boxes is $2.50
We want to know the cost for 24 juice boxes.
The jump from 8 to 24 is "times 3". So we'll multiply the $2.50 cost by 3 to get 3*2.50 = 7.50
We can think of it like this
[tex]\frac{2.50 \ \text{dollars}}{8 \ \text{juice boxes}}=\frac{3*2.50 \ \text{dollars}}{3*8 \ \text{juice boxes}}=\frac{7.50 \ \text{dollars}}{24 \ \text{juice boxes}}[/tex]

The graph illustrates a normal distribution for the prices paid for a particular model of HD television. The mean price paid is $2000 and the standard deviation is $75.
The approximate percentage of buyers who paid between $1925 and $2075 is; 68%
The approximate percentage of buyers who paid between $1925 and $2000 is; 34%
How to Interpret Normal Distribution Graph?We are given;
Mean = $2000
Standard Deviation = $75
1) We want to find the approximate percentage of buyers who paid between $1925 and $2075
The formula that is used to calculate the z-score of a a normal distribution is;
z = (x' - μ)/σ
where;
z is z-score
x' is sample mean
μ is population mean
σ is standard deviation
For a payment of 1925;
z = (1925 - 2000)/75 = -1
For a payment of2075;
z = (1925 - 2000)/75 = 1
Thus, this is 1 standard deviation from the mean.
Thus, this is a percentage of 68%
2) We want to find the approximate percentage of buyers who paid between $1925 and $2000?
For a payment of 1925;
z = (1925 - 2000)/75 = -1
For a payment of 2000;
z = (2000 - 2000)/75 = 0
This translates to a percentage of (1/2) * 68% = 34%

When $\dfrac{2}{13}$ is written as a decimal, what is the $2000^\text{th}$ digit after the decimal point?
The 2000th digit after the decimal point is 5. See the explanation below.
What is the explanation that resolved the above problem?
First, we divide the fraction to get the decimal number.
2/13 = 0.15384615384
Paying close attention, you'd notice that after the 6th number forms the decimal point, the number forms a loop that repeats again. That is:
0.153846 153846 154...
Hence, to detect the 2000th number,
we divide 2000/6
we are left with 2
(that is 333 x 6 = 1998)
Hence we count two from the decimal and that gives us the 2000th digit.

how could you use a graph of a proportional relationship to find any ratio in the the proportional relationship why does this work?
It should be emphasized that a connection is proportional if its graph is a line that passes through its origin.
How should the information be illustrated?If the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to achieve this, the ratio is not proportional.
The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a connection is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional.
Additionally, if anything is not linear, it is not proportional.

The opposite interior angles are another name for the remote interior angles. Where can I determine a triangle's outer angle? In a triangle, how can I determine the interior and outside angles?
Take the total of two interior angles of a triangle that are known and deduct it from 180 to find the internal angle of the triangle.
Simple addition of the triangle's two opposite internal angles will yield the triangle's external angle. 180° minus the inside angle equals each exterior angle. Using this formula requires the knowledge of the corresponding internal angle. Exterior angle = Total.

the value of P(E and F) is equal to 0.175 when E and F are independent events with P(E) = 0.25 and P(F) = 0.7.

Find an equation to represent a line that goes through (1, 10) and (2, 8).
y = -2x + 12 is the linear equation of the line that passes through the coordinates of points (1, 10) and (2, 8).
What is the equation of line with the given coordinates?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
The slope of a line is expressed as change in y over change in x.
Slope m = (y₂-y₁)/(x₂-x₁)
Given the data in the question;
Point 1 ( 1, 10 )
x₁ = 1y₁ = 10Point 2 ( 2, 8 )
x₂ = 2y₂ = 8First, we determine the slope of the line.
Slope m = (y₂-y₁)/(x₂-x₁)
Slope m = ( 8 - 10 )/( 2 - 1 )
Slope m = (-2)/( 1 )
Slope m = -2
Now, determine the y-intercept b, by substituting the slope and the coordinates of one point into the equation of line formula.
y = mx + b
10 = -2(1) + b
Solve for b
10 = -2 + b
b = 10 + 2
b = 12
Now that we have the slope m and y-intercept b, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = -2(x) + 12
y = -2x + 12
