1 answer:

4 0

Numbers are those integers used in a certain equation. For example: 5, 10, 5/4, 11, .1542, -100; these are all numbers despite its differences, may it be negative or positive number, may it fraction or decimals.
Variables refer to the letters used in a certain equation. For example, 5x, x is the variable used. This is usually used to represents unknown numbers.
And lastly operation and symbols, Operations are used to add, subtract, divide and multiply the given equation. Symbols are used to get the square root of a given number and more.

Round your answer to two decimal places.

Answer:

The correct answer is Hypotenuse = 3.61 units (Rounding to two decimal places)

Step-by-step explanation:

We can use the Pythagoras theorem formula for solving this questions. It can be expressed symbolically as follows:

Hypotenuse² = First leg² + Second leg²

"The amount of units comprising the hypotenuse squared is equal to the addition of the measure of both legs squared."

Hypotenuse² = First leg² + Second leg²

Hypotenuse = √(First leg² + Second leg² )

Replacing with the real values:

Hypotenuse = √(3² + 2² )

Hypotenuse = √(9 + 4 )

Hypotenuse = √13

Hypotenuse = 3.60555

Hypotenuse = 3.61 units (Rounding to two decimal places)

Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15

tatuchka [14]

Answer:

$\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right]$

Step-by-step explanation:

When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:

a column for the values of x in each equation
a column for the values of y in each equation
a column for the independent values of each equation

since our system of equations is:

$3x-5y=12\\ 4x-2y=15$

we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:

$\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right]$

Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:

$\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right]$

Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:

$\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right]$

usually there is a line separating the columns for the values of x and y, and the independent values:

$\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right]$

this is the matrix of the system of equations
