How many solutions you can obtain for a system of linear equations in 2 variables?

The result of this calculation is -20xyz. This answer can be verified by taking 5x, which is 5 times x, and -4xyz, which is -4 times xyz, and multiplying them together. This gives -20 times x times y times z, which is -20xyz.

The product of 5x and -4xyz is -20xyz.

-20xyz

5x * (-4xyz) = 5x * (-4) * xyz = -20xyz

Multiplying 5x and -4xyz together yields -20xyz. To calculate this, first take the 5x and multiply it by -4. Then take the answer and multiply it by xyz. The result of this calculation is -20xyz. This answer can be verified by taking 5x, which is 5 times x, and -4xyz, which is -4 times xyz, and multiplying them together. This gives -20 times x times y times z, which is -20xyz.

Answer:

The expression. 7 plus the sum of a number x and 5 will be written as 7 + (x + 5).

Step-by-step explanation:

From the information given, the phrase is written as 7 plus the sum of a number x and 5. Therefore, the expression will be:= 7 + (x + 5).

Let's say x is 2. The the value will be:= 7 + (2 + 5)

= 7 + 7 = 14 

In conclusion, the correct option is 7 + (x + 5).

The quotient when (x³ + 8) is divided by   (x+2) is (x² - 2x + 4)

A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates. x² + 4x + 7 is an illustration of a polynomial with a single indeterminate x.

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

The degree of a polynomial is the highest or biggest exponent of the variable in the polynomial. Using Descartes' Rule of Signs, the degree is used to calculate the greatest number of polynomial problem solutions.

The polynomials are (x³ + 8) and (x+2)

                         dividing  (x³ + 8) by  (x+2) we get,

                                     x + 2 ) x³ + 8 ( x² - 2x + 4

                                              - x³ - 2x²

                                                    -2x² + 8

                                                     2x² +4x

                                                              4x + 8

                                                             -4x - 8

                                                                  0

The table that shows a proportional relationship is Table D.

Please find attached the graph of Table D created with MS Excel

The variables x and y in a set of ordered pair (x, y), are proportionally related, when the ratios of the x and y values for of all data points in the set are equivalent, such that a proportional relationship can be expressed in the form; y = k·x

Where;

k = The constant of proportionality

Therefore; k = y/x

The ratio of the y-values to the corresponding x-values in the table that shows a proportional relationship is therefore a constant.

Analyzing the Table C, we get;

The points are; (2, 1), (4, 3), (6, 5), (8, 7)
x/y for each data point is therefore;

1/2 ≠ 3/4 ≠ 5/6 ≠ 7/8

Table C does not show a proportional relationship

The coordinate points in Table D are; (2, 1), (6, 3), (8, 4), (10, 5)

The ratio, x/y at each point in the table are therefore;

1/2 = 3/6 = 4/8 = 5/10 = 1/2

The ratio, x/y at each point in the table is constant, therefore, Table D ahows a proportional relationship.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The first box has a base that measures 8 inches by 10.5 inches with a height of 6.25 inches

8=length, 10.5=width and height=10.5

The probability that at least one psychologist is chosen is 5/9 and the probability that exactly three psychologists are chosen is 16.3.

Total number of Attendants in a certain conference are 54

There are 24 psychiatrists and 30 psychologists

Total number of attendants = 24 + 30= 54.

Therefore total number of cases is 54

1 ) Since there are 30 psychologists, the number of favorable outcomes is 30.

So P ( 30 psychologists) =Number of favorable cases/ Total number of cases

= 30/54

= 5/9.

So probability of at least one psychologist is 5/9.

2 ) If we have to choose 3  psychologist favorable outcomes are

Answer: The measure of an angle is the same as the measure of its reference angle in the first or fourth quadrant. Since, m∠884° is in the 8th quadrant, we can use the reference angle in the first quadrant, which is m∠4°.

So, m∠1 = m∠4°

To find the measure of the angle m∠3, we can use the fact that angles in different quadrants that share a terminal side have measures that add up to 180°.

m∠3 = 180° - m∠1

m∠3 = 180° - m∠4°

m∠3 = 180° - 4° = 176°

Therefore, m∠1 = m∠4° and m∠3 = 176°.

Surface area of a 9 by 4 foot space is equal to 36 feet2.

So,

Surface area of a room measuring 6 by 6 feet is 6 x 6.
