Graph the equation by plotting three
points. If all three are correct, the line
will appear.
2y = 3x + 11
pls input the 3 points
Answers
The three points to plot for the equation 2y = 3x + 11 are (0, 5.5), (1, 7), and (-1, 4).
To graph the equation 2y = 3x + 11, we can choose any three points that satisfy the equation. Let's select three points and plot them on a coordinate plane:
Point 1:
Let's set x = 0 and solve for y:
2y = 3(0) + 11
2y = 0 + 11
2y = 11
y = 11/2 = 5.5
So, the first point is (0, 5.5).
Point 2:
Let's set x = 1 and solve for y:
2y = 3(1) + 11
2y = 3 + 11
2y = 14
y = 14/2 = 7
The second point is (1, 7).
Point 3:
Let's set x = -1 and solve for y:
2y = 3(-1) + 11
2y = -3 + 11
2y = 8
y = 8/2 = 4
The third point is (-1, 4).

Please draw the ray diagram! A 3.0 cm-tall object is placed at a distance of 20.0 cm from a convex mirror that has a focal length of - 60.0 cm. Calculate the position and height of the image. Use the method of ray tracing to sketch the image. State whether the image is formed in front or behind the mirror, and whether the image is upright or inverted.
Answers
The image is formed behind the mirror, and the image is upright.
Given data: Object height, h = 3.0 cm Image distance, v = ? Object distance, u = -20.0 cmFocal length, f = -60.0 cmUsing the lens formula, the image distance is given by;1/f = 1/v - 1/u
Putting the values in the above equation, we get;1/-60 = 1/v - 1/-20
Simplifying the above equation, we get;v = -40 cm
This negative sign indicates that the image is formed behind the mirror, as the object is placed in front of the mirror.
Hence, the image is virtual and erect. Using magnification formula;M = -v/uWe get;M = -(-40) / -20M = 2Hence, the height of the image is twice the height of the object.
The height of the image is given by;h' = M × hh' = 2 × 3h' = 6 cm Now, let's draw the ray diagram:
Thus, the position of the image is -40.0 cm and the height of the image is 6 cm.
The image is formed behind the mirror, and the image is upright.

Jesse and Janie are playing a game. On the table in front of them, there are 50 coints. They take turns removing some of these coins from the table. At each turn, the person moving can remove either 1,2,3,4,5 or 6 coins (they cannot remove 0 or 7 etc). The person to remove the last coin wins. Suppose Janie is the first player to have a turn. 1) In the subgame perfect equilibrium, Janie begins by taking ______coins.
Answers
In the subgame perfect equilibrium, Janie should begin by taking three coins.
To determine Janie's optimal move, we need to work backwards from the end of the game. If there is only one coin left on the table, the next player (Jesse) will have to take it and Janie wins. Therefore, Janie's goal is to force the game to end with only one coin remaining.
If Janie takes one or two coins at the beginning, Jesse can always mirror her move and take the remaining coins on his turn, leaving one coin for Janie and guaranteeing his victory. If Janie takes four, five, or six coins, Jesse can simply mirror her move and force Janie to be the one left with one coin.
Janie should take three coins initially. This move forces Jesse into a losing position since he can only take between one and six coins. No matter how many coins Jesse takes, Janie can mirror his move and leave him with one coin on his turn, ensuring her victory in the subgame perfect equilibrium.

Answers
the completed multiplication table is: 40 45 50 ,72 54 60 and 56 90 70 .by using common factor logic we can solve this question.
what is common factor ?
A common factor is a number that divides evenly into two or more other numbers. For example, the common factors of 12 and 18 are 1, 2, 3, and 6, because all of these numbers divide evenly into both 12 and 18.
In the given question,
From the given table, we can see that:
The first row reads 40, 45, 50 (which are multiples of 5).
The second row has an unknown number (let's call it x), 54, and 60.
The third row reads 56, an unknown number (let's call it y), 70 (which are also multiples of 7).
To find the missing numbers, we can use the fact that multiplication is commutative, meaning that the order of the factors does not matter. Therefore, we can fill in the missing numbers by looking for factors that are common to both the row and column headers.
Starting with the second row, we can see that the common factor between x and 54 is 9, since 9 x 6 = 54 and 9 x x = ?. So, the missing number in the second row is 9 x 10 = 90.
Moving on to the first column, we can see that the common factor between 40 and 56 is 8, since 8 x 5 = 40 and 8 x 7 = 56. So, the missing number in the second row, first column is 8 x 9 = 72.
Finally, we can find the missing number in the first row, second column by finding the common factor between 45 and 60, which is 15, since 15 x 3 = 45 and 15 x 4 = 60. So, the missing number in the first row, second column is 15 x 5 = 75.
Therefore, the completed multiplication table is:
40 45 50

How many pounds means in 1 kg?
Answers
1 kilogram is equal to 2.20462 pounds.
Pounds (lbs) and kilograms (kg) are both units of measurement for weight, but they are not directly interchangeable. To convert a measurement of weight from kilograms to pounds, you will need to use a conversion factor.
So 1 kilogram is equal to 2.20462 pounds. The conversion factor between kilograms and pounds is 1 kg = 2.20462 lbs.
To convert a measurement of weight from kilograms to pounds, you will multiply the number of kilograms by the conversion factor of 2.20462.
For example, if you have a measurement of 3 kilograms, you would multiply 3 x 2.20462 to get 6.61386 pounds. So, 3 kg = 6.61386 lbs.
It's important to note that when measuring weight, it's important to use the same system of measurement as the requirement, as using the wrong measurements can greatly affect the outcome of the calculation. It's always good to know the conversion factors to make your calculations easier.

Answers
The equation x^2 - y^2 - 2x + 16y = 31 represents a hyperbola.
To determine the conic section represented by the equation, we analyze the coefficients of the variables and the constant term. By completing the square for the x and y terms, we rewrite the equation as (x - 1)^2 - (y - 8)^2 = -32. Since the coefficients of both the x and y terms have opposite signs, the equation represents a hyperbola.
The equation can be rewritten as (x^2 - 2x) - (y^2 - 16y) = 31.
Completing the square for the x and y terms, we get:
(x^2 - 2x + 1) - (y^2 - 16y + 64) = 31 + 1 - 64.
Simplifying further, we have:
(x - 1)^2 - (y - 8)^2 = -32.

what the metric system of measurement is based on the number?
Answers
The metric system of measurement is based on the number 10.
This system is also known as the International System of Units (SI) and is used in most countries around the world. In the metric system, various units of measurement are defined as multiples or fractions of a base unit, which is defined for each quantity being measured. For example, the base unit for length is the meter, and the base unit for mass is the kilogram. Prefixes such as kilo-, centi-, and milli- are used to indicate multiples or fractions of the base unit, based on factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and a milligram is 1/1000 of a gram. This makes the metric system easy to use and convert between units, as well as consistent and universally recognized.
