An example of an extraneous solution in math is solving the equation 1/(x−2) + 1/(x+2) = 4/(x−2)(x+2) for x.

An extraneous solution is a root of a transformed equation that is not the root of the original equation because it was excluded from the domain of the original equation.

Solve the equation 1/(x−2) + 1/(x+2) = 4/(x−2)(x+2) for x

1/(x−2) + 1/(x+2) = 4/(x−2)(x+2)

(x−2)(x+2)/(x−2) + (x−2)(x+2)/(x+2) = 4(x−2)(x+2)/(x−2)(x+2)

(x−2) + (x+2) = 4

2x = 4

x = 2

But 2 is excluded from the domain of the original equation because it would make the denominator of one of the fractions zero--and division by zero is not allowed. Therefore, it cannot be the root of the original equation. So, 2 is an extraneous solution. So, the equation has no solutions.

The measure of segment UY from the given triangle WUY is 90 units.

The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side.

Given that, VX is a midsegment of ΔUWY.

UY=13p-1 and VX=20p-95.

Since, VX is a midsegment of a triangle, we have

VX= 1/2 (UY)

20p-95 =1/2 ×(13p-1)

40p-190=13p-1

27p=189

p=189/27

p=7

So, UY=13p-1

UY=13(7)-1

UY=90 units

Therefore, the measure of segment UY is 90 units.

The required value of z in the given system of equations is 4. Option D is correct.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
3x + 5y - z = 15 - - - - (1)

x + 2y = 8 - - - - -(2)

x - 3y + 2z = - 9 - - - - (3)

Simply multiply the number of moles by 24 to obtain the volume of gas in dm3 at standard pressure and temperature.

According to the chemical formula 2 C2H6 + 7 O2 → 4 CO2 + 6 H2O + 3120 kJ, the full combustion of ethane releases 1559.7 kJ/mol, or 51.9 kJ/g, of heat along with carbon dioxide and water. Amorphous carbon and carbon monoxide can be produced when combustion doesn't involve too much oxygen.

Exothermic reactions, such as the combustion of hydrocarbons, provide heat energy. To find the volume of gas in dm3 at room temperature and pressure, simply multiply the number of moles by 24.

The typical scenario is that you are following a recipe that, for instance, calls for a 0.5 molar solution of NaOH. As you are aware, "0.5 M" refers to 0.5 moles per liter.

What is average of a data?

Averages are used to condense a large number of data points into a single value. It is a visual representation of all the data set's available numbers. By adding up all the data values and dividing them by the total number of data points, the average is calculated. To determine the average age of the students in a class, the ages of all the students are taken into account and an average is calculated.

Given that the average salary of Chicago Bulls players was $5,950,435.

The median salary was only $1,669,178.

A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it.

Since the median represents the mid-value of the data. The salary of some players may be very low. Thus median is less than the average salary.

Answer:

Step-by-step explanation:

The kind of system and equation that has many solutions is a linear system of equations with infinitely many solutions.

Equation is an expression that states the equality of two things. It is usually written using mathematical symbols, and it typically contains an equals sign (=). An equation is used to describe a relationship between two or more variables, such as the relationship between the circumference of a circle and its radius, or the relationship between a certain amount of money and the amount of interest it will generate. Equations are used to solve problems in mathematics, chemistry, physics, engineering, and other disciplines.

This means that any combination of values for the unknowns that satisfies the equation will provide a solution. A linear system of equations can be written in the form of ax + by = c, where a, b, and c are all real numbers, and x and y are the unknown variables. When the equation has infinitely many solutions, it means that for any given value of a, b, and c, there is an infinite number of possible values for the unknowns x and y. This can be seen by looking at the graph of the equation, which will be a straight line that passes through the origin, and the line will have an infinite number of points on it.

Barbara has 6 nickels, 8 dimes and 5 quarters in her purse

An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

We know that the number of dimes is three less than the sum of the numbers of nickels and quarters, so:

d = n + q - 3

2.35$ is equal to 235 cents and nickels are worth 5 cents each, dimes 10 cents each, and quarters are 25 cents each. So the values of her coins are:

5n = value of the nickels

10d = value of the dimes

25q = value of the quarters

5n + 10d + 25q = 235

Solving the equations we have:

n +d + q = 19                 (1)

d = n + q - 3                  (2)

5n + 10d + 25q = 235  (3)

By ordering the variables in the (2) equation we have:

d = n + q - 3

d - n - q = - 3

- n + d - q = -3

n      + d      + q =      19            (1)

- n    + d       - q =      -3            (2)

5n + 10d + 25q =   235            (3)

Substitute (d) for n + q - 3  in (1) and (2) equations.

n + n + q - 3 + q = 19

2n  + 2q = 22

2(n+q) = 22

n+q = 22/2

n  + q  = 11        (4)

In (2) equation:

5n + 10(n + q - 3) + 25q = 235

5n + 10n + 10q - 30 + 25q = 235

15n + 35q = 265  (5)

We now have two equations in two unknowns instead of 3 unknowns:

n +    q =   11         (4)

15n + 35q = 265  (5)

Multiply (4) equation by -15 and add:

-15n  - 15q  = -165

15n  +35q  =  265

         20q  = 100

q = 100/20

q = 5

Substitute for (q) in (4)

n + 5 = 11

n = 11-5

n = 6

Substitute (q) and (n) value in (1)

n +d + q = 19  

6 + d + 5 = 19

d = 19 - 6 - 5

d = 8

Therefore, Barbara has 6 nickels, 8 dimes and 5 quarters
