Answer:
negative 16
Step-by-step explanation:
the numbers skip by 20
Answer:
-4
Step-by-step explanation:
If you look at the table closely for the value of x decreases by 2 like the first value is 7 then it goes to 5 then it goes to 3 then to 1, and if you look at the values of y it decreases by 20 like the first number is 66 then 46 then 26 then 6.
But in the table it asks the missing value of y when x is 0 not -1 so for difference of 1 instead of the usual 2 in the pattern the value of y would decrease by 10 instead of 20 so 6-10 would be -4
so the missing value of y is -4

characterize the slope of the line in the graph
Answer:
Please check the attached graph.
Step-by-step explanation:
Note: You did not add the graph; so I am taking a sample graph to clear the concept anyway. Please check the referred graph attached below.
The slope on the graph basically tells us the time rate of change.
In other words, it describes the steepness of a straight line.The slope can also be termed as:
Slope = rise / runFrom the attached graph, taking twp points
(0, 3)(-1, 0)Finding the slope between (0, 3) and (-1, 0) using the formula
[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-3}{-1-0}[/tex]
[tex]m=3[/tex]
Thus, the slope of the given line on the graph = m = 3

What is the 10th term of the sequence 729, 243, 81, 27...? Enter any rational answer
in the form a/b or round to the nearest thousandth.
Help please.
Answer:
The 10th term of the sequence is:
[tex]a_{10}=\frac{1}{27}[/tex]Step-by-step explanation:
Given the number
729, 243, 81, 27...
A geometric sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_0\cdot r^{n-1}[/tex]
Computing the ratio of all the adjacent terms
[tex]\frac{243}{729}=\frac{1}{3},\:\quad \frac{81}{243}=\frac{1}{3},\:\quad \frac{27}{81}=\frac{1}{3}[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=\frac{1}{3}[/tex]
also
[tex]a_1=729[/tex]
Therefore, the nth term is computed by:
[tex]a_n=729\left(\frac{1}{3}\right)^{n-1}[/tex]
Putting n = 10 to find the 10th term
[tex]a_{10}=729\left(\frac{1}{3}\right)^{10-1}[/tex]
[tex]=729\cdot \frac{1}{3^9}[/tex]
[tex]=\frac{1\cdot \:729}{3^9}[/tex]
[tex]=\frac{729}{3^9}[/tex]
[tex]=\frac{3^6}{3^9}[/tex]
[tex]=\frac{1}{3^3}[/tex]
[tex]a_{10}=\frac{1}{27}[/tex]
Therefore, the 10th term of the sequence is:
[tex]a_{10}=\frac{1}{27}[/tex]

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).

Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 2x + 1
y =
Okay!
Whenever a line is parallel to another, that means they ALWAYS have the same slope!
So the slope of our new line is -2 as well !
Now let's use point C (2, 8) to find the y-intercept!
This is easy! All we need to do is plug the point in our new equation!
Remember that in point C, 2 = x and 8 = y
Time to plug in all these numbers in y = mx + b
8 = -2 (2) + y intercept
→ the 8 is in the y's place
→the -2 is in the slope place
→2 is in the x place
Now we solve for the y-intercept using basic math!
8 = -2(2) + y-intercept
8 = -4 + y-intercept
8 + 4 = y-intercept
We did it! We found the y-intercept
The y-intercept is 12!
Now let's create our final equation ...
y = -2x + 12

Step-by-step explanation:
In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.
The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.
Basically:
[tex]x^2 + y^2 = h^2[/tex]
Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:
[tex]x^2 = h^2 - y^2[/tex]
[tex]x=\sqrt{h^2 - y^2}[/tex]
Then plug in the values:
[tex]x = \sqrt{16^2 - 10^2} = \sqrt{256-100}=\sqrt{156} = 2\sqrt{39}=12.489996[/tex]

Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
He has 72 pencils and 24 calculators and he must use all of the pencils and calculators.
If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer: 3 Pencils
Step-by-step explanation:
In order to know how many packages Zayed can make, we need a number that is a factor of 72 and 24, so that the 72 pencils and the 24 calculators can be divided evenly.
So, if there wre 2 packages, there would be 72 / 2 = 36 pencils 24/ 2= 12 calculators in each package. This creates packages, but isn't the gratest number of packages!
To find the greatest number of identical packeges, we want to found the greatest common factor of 72 and 24
To do so, lets find the factors of 72 and 24
72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
24: 1, 2, 3, 4, 6, 8, 12, 24
the gratest common number factor of 72 and 24 is 24. in math notation this looks like:
gcf (72, 24)=24
the gratest number of identical packages can make is 24
To find the umber of pencils in each pacage, we need to dovide the total number of pencils by the number of pakages:
72 / 24 = 3.
there will be 3 pencils each package
