Step-by-step explanation:

Let x be sister

equation = (x + 2x) = 36

classify each polynomial by degree and number of terms.

Answers


Polynomials can be classified two different ways - by the number of terms and by their degree.

1. Number of terms.

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2


Practice classifying these polynomials by the number of terms:

1. 5y

2. 3x2-3x+1

3. 5y-10

4. 8xy

5. 3x4+x2-5x+9

Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial

2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Answer:

1) Monomial

2) Trinomial

3) Binomial

4) Monomial

5) Polynomial

Find the cardinal number of set A = { a, b, c, d, e, f}
if answered correctly and answer is explained I will give brainliest!!!!

Answers

Answer:

What is the cardinal number of a set?

The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’.

For example:

(i) Set A = {2, 4, 5, 9, 15} has 5 elements.

Therefore, the cardinal number of set A = 5. So, it is denoted as n(A) = 5.

(ii) Set B = {w, x, y, z} has 4 elements.

Therefore, the cardinal number of set B = 4. So, it is denoted as n(B) = 4.

(iii) Set C = {Florida, New York, California} has 3 elements.

Therefore, the cardinal number of set C = 3. So, it is denoted as n(C) = 3.(iv) Set D = {3, 3, 5, 6, 7, 7, 9} has 5 element.

Therefore, the cardinal number of set D = 5. So, it is denoted as n(D) = 5.

(v) Set E = {   } has no element.

Therefore, the cardinal number of set D = 0. So, it is denoted as n(D) = 0

Step-by-step explanation:

Using the cardinality concept, it is found that the cardinal number of the set is of 6.

------------------------------------------------------

The cardinality of a set is given by the number of unique elements in the set.For example: set {a,a,a} has cardinality 1, as there is only one unique element, which is a.set {a,b,c} has cardinality 3, as there are three unique elements, which are a,b and c.set {a,a,b} has cardinality 2, as there are two unique elements, which are a and b.

------------------------------------------------------

set {a,b,c,d,e,f} has cardinality 6, as there are 6 unique elements, which are: a, b, c, d, e and f. Thus, the cardinal number of the set is of 6.

Answers

Answer:

-9

Step-by-step explanation:

18÷x = -2

18 = -2×x

18 = -2x

-9 = x

x = -9

Answer:

-9

Step by step explanation:

it can also be written as; 18 over x is equal to -2 over 1

you cross multiply to get 18 = -2x

then multiply through with -2; 18 over -2 = -2x over -2

you cross out; -2 cancels itself and -2 goes into 18 , -9 times

Therefore; the answer is -9

What is the value of y if x is 8 in the linear equation graphed?

A) 4
B) 5
C) 7
D) 13

Answers

Answer:

When x = 8, our y-value is equal to 13.

Step-by-step explanation:

We are given a graph that shows a linear relationship between our variables x and y.

In math, the slope-intercept form of an equation is written as:

[tex]\bullet \ y=mx+b, \text{where m is our slope and b is our y-intercept.}[/tex]

We also can note that there is another way to state a function: [tex]f(x)[/tex]. This replaces the y in the slope-intercept form and they can be used interchangeably.

[tex]\bullet \ f(x) = mx + b[/tex]

So, when we look at our graph, we can see that we have x-values on the bottom horizontal axis and y-values on the left vertical axis.

When we check this, we see that our x-values range from 0 to 9 and our y-values range from -2 to 14.

Therefore, we can see that since x is supposed to be equal to 8, we are going to draw a vertical line from x = 8 and see what point this intersects.

We see that the line would intersect the rightmost point and it is located between y = 12 and y = 14.

Therefore, we can just take the median of these two values and find our y value.

[tex]\displaystyle 12 + 14 = 26\\\\\frac{26}{2} = 13[/tex]

Therefore, y is equal to 13 and our answer is Choice D.

It is recommended that you work this out on graph paper to help answer the questions. Sean plots the locations of 4 places on a coordinate grid as given below (It is recommended that you work this out on graph paper to help answer the questions.): His house is at (−4, 5). His school is at (−4, 3). The community center is at (6, 3). The grocery store is at (−4, −9). Part A: Use absolute values to calculate the distance in units from Sean's house to his school. Show your work. (4 points) Part B: Is the total distance from Sean's house to the school to the grocery store greater than the total distance from Sean's house to the school to the community center? Justify your answer.

Answers

Formula of finding the distance : absolute value (x2-x1)^2 + (y2-y1)^2
Distance from house to school : (Under Absolute value) (x2-x1)^2 + (y2-y1)^2
( -4 - (-4) )^2 + (10 - 3 )^2 = 0 + 49 = Radical 49 = 7
Distance from house to grocery store : (using the same method) you get = Radical 1200 = 60
Distance from house to community center : (using the same method) =
Radical 85
Yes, the distance from her house to grocery store is greater then to community center

The points are

[tex]H(-4,5)[/tex]

[tex]S(-4,3)[/tex]
