There are 364 solutions to the given inequality: x1 + x2 + x3 <= 11.
To get the solution of the inequality x1 + x2 + x3 <= 11, we first need to include an additional variable in the inequation to write in as an equation.
Therefore, let the additional variable be x4.
Thus, equation is x1 + x2 + x3 + x4 = 11
The number of solutions of an equation can be calculated by the formula,
[tex]( \left \ {{n+ r - 1} \atop {n}} \right.)[/tex], where n is the constant value of the equation and r is the number of variables in the equation.
In this case, n = 11 and r = 4
Therefore,
[tex]( \left \ {{n+ r - 1} \atop {n}} \right.)[/tex] = [tex]( \left \ {{11+ 4 - 1} \atop {11}} \right.)[/tex] = [tex]( \left \ {{14} \atop {3}} \right.)[/tex]
= 14 * 13 * 12 * 11!/(3 * 2 * 1 * 11!)
=2184/6 = 364
Therefore, there are 364 possible solutions of the inequality.

The solution to the system of equations is y equals 1. 5 x 4 and y equals negative x is-= (1.6,-1.6)
In this case option A is correct
The coordinates of the ordered pair (s) that satisfy all of the equations in the system are the solution set to a system of equations. To put it another way, those x and y values will make the equations true. As a result, when a system of equations is graphed, the intersection points of the graphs are the system's solution.

Max puts a stopper in the bathtub and turns on the faucet at t = 0.
After 5 minutes, there are 11 gallons of water in the tub and after 10 minutes, there are 22 gallons in the tub.
Write an equation that relates the number of gallons, g, to the time, t.
Does the relationship represent a linear function? Justify your response.
The equation is y = 2.2x. Yes, it represents a linear function.
What is a linear function?
A linear function is one that has the highest degree of 1 possible. This indicates that there are no variables in a linear function with exponents greater than 1. Such an equation on the graph, forms a straight line.
We are given that
Stopper is applied at t = 0
At t = 5 minutes ; water in tub = 11 gallons
At t = 10 minutes ; water in tub = 22 gallons
We know that a general form of a linear function is y = mx + c.
Where c is the intercept ; m is the Slope ; y and x are dependent and independent variables respectively
Here, the intercept is gallon of water at t = 0 ;
Since, it is not mentioned, therefore it will be taken as 0.
Slope = change in y / change in x
Slope = (22 - 11) / (10 - 5)
Slope = 11 / 5
Slope = 2.2
Therefore, the equation becomes
y = 2.2x + 0
y = 2.2x

Why are complex fractions called complex?.
Complex fractions are called complex because they contain one or more fractions within the numerator and/or denominator of the fraction. These fractions within the fraction make the fraction more complex or difficult to simplify than a regular fraction, which only has a single numerator and denominator.
The term "complex" in mathematics often refers to something that is composed of multiple parts or layers, and that requires more steps or understanding to work with or solve.
In this case, the presence of one or more fractions within the fraction makes it more complex than a regular fraction, hence the name "complex fraction."
Another reason for the term complex is that the fractions in the numerator and denominator may have different or even the same variables, making it difficult to cancel them or simplify the expression.

A large concrete block is used for the cornerstone of a building. The block is 18 yd deep, 23 yd wide, and 16 yd long. What volume of concrete is needed to make this block?
Answer:
Step-by-step explanation:
To find the volume of concrete needed to make this block, you need to calculate the volume of the block using the formula:
Volume = Length x Width x Height
In this case:
Volume = 18 yd x 23 yd x 16 yd = 7,648 cubic yards
So, 7,648 cubic yards of concrete are needed to make this block.
Alternatively, you can use the formula:
V=LWH, where V is the volume, L is the length, W is the width and H is the height.
How many solutions does Y =- 3x 5 have?.
The given equation y = -3x + 5 has infinitely many solutions.
We have linear equation y = -3x + 5
We need to encounter how many solutions can satisfy the given equation.
We know that,
y = -3x + 5 is a linear equation in two variables in the form ax + by + c = 0
For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.
For x = 1, y = -3 × 1 + 5 = 2. Therefore, (1, 2) is another solution.
For y = 0, -3x + 5 = 0, x = 5/3. Therefore, (5/3, 0) is another solution.
Clearly, for different values of x, we get different values for y. Thus, any value substituted in the place of x in the given equation will form another solution for the given equation. So, there is no limitation to the number of different solutions obtained by substituting real values for x in the given linear equation. Thus, a linear equation in two variables can have infinitely many solutions.
Thus, y = -3x + 5 has infinitely many solutions.

In the word problem the number of the adult ticket is 225.
What is word problem?
Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a word problem in computational mathematics.
Here total number of tickets = 516.
Which is contains adult and students tickets. Then let us take x is number of adult ticket and y is number of student tickets then,
=> x + y = 516 ------> 1
Now there were 66 more student tickets sold than adult tickets then
=> y = x+66 -----> 2
Now put 2 into 1 then
=> x+66+x = 516
=> 2x = 516-66 = 450
=> x = 225.
Now put x = 225 into then
=> y = 225+66 = 291.
Hence the number of adult tickets is 291.

Will the quotient of the division problem shown below be positive or negative?
(-8) ÷ (-4)
Answer: Positive
Hope this helps :)
Step-by-step explanation:
When multiplying or dividing with two negative numbers, the product/quotient will always be positive.
-8/-4 = 2
Answer: Positive
Step-by-step explanation:
Example for multiplication:
Imagine 4 friends that owe you $8 each.
Each friend that pays you back represents their payback as -$8.
-$8 * 4 friends = -$32 that they owe you.
The moment they give it back, you now have +$32. The Debt was taken away.
Example for Division:
Imagine splitting 8 dollars in debt with 4 friends, each friend then has $2 in debt. Each payback means you have +$2.
Another visual way to think of this is with Number Lines.
On a number line, when you multiply by a larger absolute value the numbers get bigger and go farther away from 0. So, taking a negative and multiplying it by a positive makes it MORE negative, as opposed to multiplying it by negative and then it reflects the number line,

How do you graph inverse operations?.
The inverse operations can be graphed by determining the inverse of the function by swapping the x and y variables,
Not all functions have inverses, and in order for a function to have an inverse, it must be a one-to-one function that is, there must not be repeated output for many inputs which indicates that not all functions have inverses. The various steps to graph inverse functions can be noted as -
By switching the x and y variables, first determine the function's inverse, and then solve for y. The inverse function, for instance, will be x = f-1 if the original function is y = f(x) (y).By switching the original function's x and y values, plot the inverse function's points. For instance, if the original function is y = 2x + 1, the inverse function would be x = (y-1)/2, and instead of plotting the point (0,1), you would plot (1,0), (2,-1) and so on (-1,2)Over the line y = x, reflect the original function's graph. You will then be shown the inverse function's graph.Lastly, it is required to correctly identify the axes and the points.Read more about inverse operations on:

Attendance i decreaing at a rate of 0. 5% per year. If there are 1200 people attending now how many will be attending in 4 year?
So, in 4 years, there will be 1176 people attending.
To find out how many people will be attending in 4 years, you need to determine the total decrease in attendance over that time period. The attendance is decreasing at a rate of 0.5% per year, so over 4 years, the decrease in attendance will be 4 years x 0.5% = 2%
To find out how many people will be attending in 4 years, you can then subtract the 2% decrease from the current attendance of 1200 people:
