What is system of equation?A system of equations are the set of equations where the solution for these equations are the intersecting point between the equations.
The systems of equations are given below are given below,
(a) -2x + 3y = 1(using elimination method)
2x+6y= 2
eliminating x term we get,
9y = 3
⇒y=3.
(b) y = x + 4 ---(1)(using substitution method)
x = -3y---(2)
Substitute (2) in (1) we get,
y = -3y+4
⇒4y=4 ⇒y=1
(c) 3x - y = 7 (using graphing method)
y = 3x - 2
This system has no intersection point
So this system has no solution.
( The graph is attached below.)
(d) x + 2y = 1-----(1) (using elimination method)
3x + 5y = 8-----(2)
For eliminating x we have to the multiply equation(1) by 3,
we get 3x+6y=3
eliminating 3x we get, y=-5/3 substitute y in (1) we get x=49 /3
Hence, the equations are solved using graphing, elimination, substitution methods.

The Drama club is selling tickets to a play for x dollars each for each ticket they sell the school receives x dollars and the drama club receives the remaining amount the drama club sells 108 tickets for a total of (108x+972) how much money does the drama club receive for each ticket they sell i need to show work thanks !!! your are the best
Answer:
The drama club receives $9 for each ticket they sell.
Step-by-step explanation:
The total amount of money the drama club receives from selling 108 tickets is the difference between the total amount collected and the amount donated to the school.
Total amount collected = 108x + 972
Amount donated to the school = 108x
Amount received by the drama club = (108x + 972) - 108x = 972
Therefore, the drama club receives a fixed amount of $972 for selling 108 tickets.
To find how much money the drama club receives for each ticket sold, divide the total amount received by the number of tickets sold:
972/108 = $9
Therefore, the drama club receives $9 for each ticket they sell.

what is the morse fall scale
The Morse Fall Scale (MFS) is a standardized tool used to assess a patient's risk of falling. It is used by healthcare professionals in a variety of clinical settings, including hospitals, long-term care facilities, and home care.
The MFS was first developed in 1987 by Dr. Morse and her colleagues as a way to identify patients at high risk for falls and to implement fall prevention measures. The MFS is a quick and simple tool that assesses six different risk factors for falls. These risk factors include history of falling, secondary diagnosis, ambulatory aids, intravenous therapy, gait, and mental status. The MFS assigns points to each risk factor based on the severity of the risk, with a maximum score of 125. Patients who score higher on the MFS are considered to be at higher risk for falls and require more intensive fall prevention interventions. The MFS is useful for healthcare professionals in identifying patients at risk for falls and in developing an individualized fall prevention plan. The MFS is also useful in measuring the effectiveness of fall prevention interventions by allowing healthcare professionals to track a patient's progress over time. However, it is important to note that the MFS is only one tool in a comprehensive fall prevention program and should not be used in isolation.
In summary, the Morse Fall Scale is a standardized tool used to assess a patient's risk of falling. It is a simple and quick tool that assesses six different risk factors and assigns points based on the severity of the risk. The MFS is useful in identifying patients at risk for falls and in developing an individualized fall prevention plan.

write a boolean expression that is true if the value of x is equal to zero.
The boolean expression that is true if the value of x is equal to zero is:
x == 0
Let's us first learn about Boolean expression.
A boolean expression is an expression that evaluates to either true or false. It can be created using comparison operators, such as == (equal to), != (not equal to), < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to). These operators compare two values and return a boolean result.
In this question, the double equal sign (==) is the comparison operator for equality in many programming languages, and it returns true if the values on both sides are equal, and false otherwise.
So in this case, the expression "x == 0" would return true if x is equal to zero, and false otherwise.

11. A) A mobile price is tagged Rs 5,000. If a customer gets 12% discount and adding certain
percent VAT reaches as Rs 4,972, find out the VAT percentage.
The VAT percentage of a mobile price is tagged Rs 5,000 with a 12% discount and adding a certain percentage of VAT reaches Rs 4,972 is a 13% VAT Percentage.
The solution to the problem is as follows:
Step 1: Find the price of the mobile after the discount. The discount is 12% of the original price, which is Rs 5,000. So, the discount amount is:
12% of Rs 5,000 = (12/100) * 5000 = Rs 600
Step 2: Subtract the discount amount from the original price to get the price after the discount:
Rs 5,000 - Rs 600 = Rs 4,400
Step 3: Now, we need to find the VAT percentage that was added to the price after the discount to get the final price of Rs 4,972. Let the VAT percentage be x%. Then the equation is:
Rs 4,400 + x% of Rs 4,400 = Rs 4,972
Step 4: Simplify the equation and solve for x:
4400 + (x/100) * 4400 = 4972
4400 + 44x = 4972
44x = 4972 - 4400
44x = 572
x = 572/44
x = 13

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
1 roll = 3 feet of ribbon
So, 5 rolls = 5 x 3 = 15 feet of ribbon
and, 1 foot = 12 inches
Then, 15 feet = 15 x 12 = 180 inches
The dressmaker has 180 inches of ribbon in total.

how to calculate hexagon sum of interior angles
Answer:
Step-by-step explanation:
The sum of the interior angles in a polygon can be calculated using the following formula:
(n - 2) * 180 degrees
where n is the number of sides in the polygon.
To understand why this formula works, let's consider a single interior angle in the polygon. Each interior angle is split into two equal angles that form a straight line. The sum of these two angles is 180 degrees. Now, if we look at all the interior angles in the polygon, we can see that they are divided into (n - 2) pairs of angles that form straight lines. This means that the sum of all the interior angles in the polygon is (n - 2) * 180 degrees.
For a hexagon, which has 6 sides, we can plug in n = 6:
(6 - 2) * 180 = 4 * 180 = 720 degrees
So, the sum of the interior angles in a hexagon is 720 degrees.
