what is the relation ships for 1 2 3 4 5 and n please help
To find the relationship you:
1. The relation can be the difference between every term in the sequence:
In the first sequence you have between every term a diferencen of:
Where n is the term
Youn can notice that the relationship is the way you get that term and is equal to the previous term plus an odd number (3,5,7,9), as the sequences do not have a constant difference the sequence is a non-regular succession. But as the set of differences (1,3,5,7,9) Follows a regular succesion of (2n-1) you have quadratic sequences that have the next formula:
1. First sequence:
[tex]n^2+10[/tex]2. Second sequence:
[tex]n^2-4[/tex]Find the values of x and y. (90 - 4y)° (50 - 2x)° (х +5y)° (2x+3y)°
1) According to the Vertical angle Theorem
We can state that
50-2x =90-4y
-2x +4y=90
2x -4y = -90
In addition to that, since those three angles make up a straight angle:
2x +3y + x +5y +50 -2x = 180º Combine like terms
x+6y =180º
2) Now, we can set this linear system:
x +6y = 180 x-2 To eliminate x
2x -4y = -90
-2x -12y =-360
2x -4y = -90
----------------
-16y = -450
16y= 450
y = 28.12
y ≅ 28
x + 6(28)=180
x+168=180
x=12
Stella rewrites -2 1/2 plus 3.7 using commutative Property of addition. Which expression did she write?
The rule for the commutative property of addition is:
a + b = b + a
Stella writes:
[tex]-2\frac{1}{2}\text{ plus 3.7}[/tex]This can be expressed mathematically as:
[tex]-2\frac{1}{2}+3.7[/tex]Which according to the property of commutativity can also be written as:
[tex]\begin{gathered} 3.7\text{ + (-2}\frac{1}{2}) \\ 3.7\text{ - 2}\frac{1}{2} \end{gathered}[/tex]The expression Stella wrote based on the commutative property of addition is therefore:

Answer:
8
Step-by-step explanation:
Counting up from 1 to 10 you go:
1 2 3 4 5 6 7 8 9 10
As you can see the eight is further to the right meaning it has more value.

What are irrational numbers?Proceeding from definition of rational numbers we say that rational numbers are real numbers that can be expressed as a fraction.
hence such numbers can have areal number in the numerator and a real number in the denominator.
Irrational numbers are the opposite of rational numbers such that when numbers cannot be expressed as fraction such number is said to irrational number.

Given:
The number of games played by 15 players are,
22, 123, 104, 150, 121, 162, 79, 151, 155, 142, 156, 144, 123, 87, 130.
The objective is to find five number summary for the number of games.
Explanation:
The five number summary are minimum value, quartile 1, median, quartile 2 and maximum value.
Increasing order:
The increasing order of the given data is,
22, 79, 87, 104, 121, 123, 123, 130, 142, 144, 150, 151, 155, 156, 162.
Minimum and Maximum value:
By considering the increasing order of the data, the minimum value is 22 and the maximum value is 162.
To find median:
The median can be calculated as the middle term of total number of data.
Since, the total number of data is 15, which is odd, then the median can be calculated as,
[tex]\begin{gathered} \text{Median}=\frac{15+1}{2} \\ =\frac{16}{2} \\ =8th\text{ term} \end{gathered}[/tex]Thus, the 8th term of increased order is 130.
To find Q1:
The quartile 1 can be defined as the middle term of the left side of the median.
Since, the left side of the median contains 7 terms, which is odd, then the quartile 1 can be calculated as,
[tex]\begin{gathered} Q1=\frac{7+1}{2} \\ =\frac{8}{2} \\ =4th\text{ term (left)} \end{gathered}[/tex]Thus, the 4th term on left side of median is 104.
To find Q3:
The quartile 3 can be defined as the middle term of the right side of the median.
Since, the right side of the median contains 7 terms, which is odd, then the quartile 3 can be calculated as,
[tex]\begin{gathered} Q3=\frac{7+1}{2} \\ =\frac{8}{2} \\ =4th\text{ term (right)} \end{gathered}[/tex]Thus, the 4th term on right side of median is 151.
Hence, the five number summary are,
Min: 22
Q1: 104
Median: 130
Q3: 151
Max: 162.
what are the x and y-intercepts of the line described by the equation? 3x - 9y = 10.8A) x-intercept = 1.2 y-intercept = 3.6B) x-intercept = -3.6 y-intercept = 1.2C) x-intercept = 1.2y-intercept -3.6D) x-intercept = 3.6 y-intercept = -1.2
we have the equation
3x - 9y = 10.8
Remember that
x-intercept ----> value of x when the value of y is zero
so
For y=0
substitute
3x-9(0)=10.8
3x=10.8
x=3.6
y-intercept -----> is the value of y when the value of x is zero
For x=0
3(0)-9y=10.8
-9y=10.8
y=-1.2
therefore
the answer is option DChoose the equation that satisfies the data in the table. in pic
Question:
Solution:
Note that if we evaluate x = -1, 0, and x=1 in the last equation we get:
y = 3(-1)+ 3 = -3+3 = 0
y = 3(0)+3 = 3
y = 3(1)+3 = 6
So that, we can conclude that the correct solution is
D. y =3x + 3

One simple method to predict adult height is to average the parents’ heights in inches and then add 2.5 inches if the child is a boy or subtract 2.5 inches if the child is a girl. This method can be fairly accurate, but can also be as much as 5 inches above or below the child’s eventual height.Use the variable D, which means height of dad and M, which means height of mom1. Write the formula for a boy’s adult height.(5 points) 2. Write the formula for a girl’s adult height.(5 points)
We are given that a boy's height is predicted by adding 2.5 inches to the average of the height of the parents. If "D" is the height of the father and "M" is the height of the mother then the average is determined by adding the two heights together and dividing by 2, like this:
[tex]\frac{D+M}{2}[/tex]Since the height of the boy is determined by adding 2.5 inches to this average, this means that the height of the boy "B" is:
[tex]B=\frac{D+M}{2}+2.5[/tex]The height of a girl "G" is determined by subtracting 2.5 to the average, therefore we have:
[tex]G=\frac{D+M}{2}-2.5[/tex]The Associative Property applies to which operations? Check all that apply. A. divideb -c.xD+

An organism is losing half of its weight each day. The function y=(0.5)^x represents the percent (in decimal form) of the original weight of the organism. where x is the number of days since the organism began to lose weight A. Describe the domain and range of the function. Then graph the function.B. Find and interpret the y interceptC. What percent (in decimal form) of the original weight does the organism weigh on the 5th day?
the domain of this function is:
[tex]x\in\lbrack0,\infty)[/tex]because we count the days.
The range is
[tex]y\in(0,1_{}\rbrack[/tex]because the maximum value of the percentage of wait is 100% = 1
the y- intercept in this case is when the organism has not lose any weight. So the percentage of weight is 100% (1 in decimal form)
after 5 days we get

graph CDE and its image reflection in the given line
C (3,4)
D (2,-1)
E (0,-5)
reflection line: y-axis
If we locate these three points on a graph, we will obtain the following:
now, the reflection points in the y-axis are calculated by multiplying x * -1 ,
for example: the new location for point C is C' = (3*-1 , 4) , therefore, C ' = (-3,4), following the same logic,
D(2,-1) -> D' (-2,-1)
E(0,-5) -> E' (0,-5)
notice that E does not change its location, since it is located on the y-axis, so it doesn't have a relfection.
Now, the graph with the points reflected is the following:

Define fraction.A fraction is a number that is a component of a whole. By breaking a whole into a number of parts, it is evaluated. For instance, the symbol for half of a complete number or item is 12. The components of a whole or group of items are represented by fractions. A fraction consists of two components. The numerator is the figure at the top of the line. It details the number of equal portions that were taken from the total or collection. The denominator is the figure that appears below the line. A fractional equation is one in which one or more of its terms have the unknown as their denominator.
