Answer 1

The solutions of the given system of Equations are (5/2, 41/2).

What are the Solutions of Equations:

The set of values for each variable in a system of linear equations is referred to as the solution set.

The intersection or meeting points of the lines or planes used to illustrate the linear equations are also known as the solutions.

The elimination method is one way of resolving a system of linear equations. To obtain the equation in one variable using this technique, simply add or subtract the equations.

Here we have

y = 9x-2 --- (1)

y = 7x+3 --- (2)

From (1) and (2)

=>  9x - 2 = 7x + 3

=>  9x - 7x = 3 + 2

=> 2x = 5

=> x = 5/2

Substitute x = 5/2 in (1)  

=> y = 9(5/2) - 2  

=> y = (45/2) - 2

=> y = (45 - 4)/2

=> y = 41/2

Therefore,

The solutions of given system of Equations are (5/2, 41/2).

choose an equivalent expression for [(2/3)^4 (2/3)^3]^2

Answers

By using exponent properties, we will find the equivalent expression:

[(2/3)^4*(2/3)^3]^2 = (2/3)^14

How to find an equivalent expression?

There are two exponent properties that we can use here, these are:

a^x*a^y = a^{x + y}

(a^x)^y = a^{x*y}

Now we have the expression:

[(2/3)^4 (2/3)^3]^2

If we use the first property, we can rewrite the expression as:

[(2/3)^4 (2/3)^3]^2 = [(2/3)^{4 + 3}]^2

[(2/3)^{4 + 3}]^2  =  [(2/3)^7]^2

Now we can use the second property to get:

[(2/3)^7]^2 = (2/3)^{7*2} = (2/3)^14

That is the equivalent expression.

We have "No Solutions" or "Infinite Solutions" case.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the unit cost of Craft paper be x.

let the unit cost of boxes of markers be y.

let the unit cost of glue sticks be z.

So, the system of equations are

The total cost to transport 12 tons of sugar is $9600.

Whet is the equation to find the total cost to transport 12 tons of sugar?

From the information, Sugar Sweet company is going to transport its sugar to the market. It will cost $7500 to rent trucks, and it will cost an additional $175 for each ton of sugar transported.

Let C represent the total cost ( in dollars)

Let s represent the amount of sugar.

The equation to find the total cost to transport 12 tons of sugar will be:

C = 7500 + (175 × s)

C = 7500 + 175s

C = 7500 + (175 × 12)

C = 7500 + 2100

What is the solution set of the equation( 6/m)+2 = (m+3)/(m−1)?

Answers

Solution set of the equation is -3,-1, and 2 by simplifying the equation we get m³+2m²-5m-6 = 0

What is equation ?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Mathematical algebraic equations typically have one or more variables.

Given equation is: (6/m)+2 = (m+3)(m-1)

multiply with m both sides,

⇒6+2m = m(m²+2m-3)    

⇒m³+2m²-3m = 6+2m

So we get,

m³+2m²-5m-6 = 0

Solving we get, m = -3, m = -1, m = 2 as solution of given equation.

One of the easiest methods for resolving a system of linear equations is graphing. Simply plot each equation as a line on a graph and identify the point or points where the lines converge to find the value. These equations are simple to graph because they are already expressed in slope-intercept form.

m = -(4+m)+2

m = -4 -m + 2

m = -2 - m

m + m = -2

What are the linear functions?

The slope-intercept definition used to define a linear function from it's graph is given as follows:

y = mx + b.

In which the coefficients are listed as follows:

m is the slope, representing by how much y changes when x is increased by one.b is the y-intercept, representing the value of y when the graph of the function crosses the y-axis.

For the red line, two points are given as follows:

(0,4) and (1,0)

Hence the parameters are of:

b = 4, a when x = 0, y = 4.m = -4, as when x increases by one, y decays by 4.

Thus the equation is of:

y = -4x + 4.

For the blue line, the equation is of:

y = x - 2.

As:

When x = 0, y = -2.When x increases by 2, y also increases by 2, hence the slope is of m = 2/2 = 1.

The IQR represents the variation between Q3 and Q1. We use the median to summarize a typical value rather than the mean when a data collection contains outliers or extreme values. The interquartile range, which is the difference between the first and third quartiles, is a statistic that is frequently used to summarize variability in data sets with outliers.

Here,

The first and third quartiles would need to be located initially. Then, to obtain the IQR, you would divide the third quartile by the first.

The mean of the temperatures is 29°C, which corresponds to answer B.

A rectangular box of sand measures 4 inches by 12 inches by 16 inches. When resting on its smallest face, the level of the sand is 4 inches from the top of the box. How many inches from the bottom of the box will the sand level reach when the box is placed on its largest face?

Answers

The level of the sand in the box when the box is placed at the largest face will be 3 inches.

What is volume?

Volume is the scalar quantity of any object that specified occupied space in 3D.

Volume has units of cube example meter³,cm³, etc.

The volume of the cube = side³.

The volume of sand when placed on a small face (4 x 12) will be as follows,

Volume = 4 x 12 x (16 - 4) = 4 x 12 x 12

When the box was kept at the largest face (16 x 12) the volume was still the same.

Let's say it goes up to h.

h x 16 x 12 = 4 x 12 x 12

h = 12/4 = 3 inches

Hence "The level of the sand in the box when the box is placed at the largest face will be 3 inches".

Compute mean for list of values and return mean for python

Python is a dynamic, high-level, free open source, and interpreted programming language.

What are basics of Python?So let's begin by looking at them:Properties. Python is implicitly and dynamically typed, so you do not have to declare variables. ...Data types. Let's move ahead to data types. ...Strings. Let's move on to strings. ...Flow control statements. ...Functions. ...Classes. ...Exceptions. ...File I/O.Python 3 was used for the above code.Each function in the above code is defined starting with the keyword def, the name of the function (mean, median, mode, main) and a pair of parentheses containing the parameter.The various defined functions in the module are saved as stats.py in the text editor.

What amount will reduce the amount due on an invoice of $ 9410.25 by $ 842 if the terms of the invoice are 5/10, n/30 and the payment was made during the discount period?

Answers

The required amount of $799.90 will reduce the amount by $842.

Given that,
The amount will reduce the amount due on an invoice of $ 9410.25 by $ 842 if the terms of the invoice are 5/10, n/30 and the payment was made during the discount period is to be determined.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
For 5/10  and n /30
The discount would be 5% if paid in the 30-day span,
Amount = amount invoiced [1 - 5%/100]
Amount = $842[0.95]
Amount = $799.9

Thus, the required amount of $799.90 will reduce the amount by $842.
