What i xant understand ined pic
To encode a message, James first replaces each letter within the message with its
corresponding number, where A = 1, B = 2, · · · , Y = 25, and Z = 26. Next, James
multiplies each number by 3 and then subtracts 5, and continues this process a total
of n times. For example, when n = 2 the letter D is encoded to the number 16.
If James encoded a four letter message to the four numbers 367 205 853 1339, what
is the value of n that he used?
(A) 2 (B) 3 (C) 4 (D) 5 (E) 6
The value of n is 4. That means, the process is applied 4 times.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
To encode a message,
James first replaces each letter within the message with its corresponding number, where A = 1, B = 2, · · ·, Y = 25, and Z = 26. Next, James multiplies each number by 3 and then subtracts 5, and continues this process a total of n times.
To find the value of n:
We use process inversely.
Let m be the given number.
For example,
m = 16
The inverse process;
add 5 and then divide by 3 until we get the whole number.
So, first time
(16 + 5)/3 = 21/3 = 7,
Second time applying process,
(7+5)/3 = 4.
And the corresponding letter is D.
And the value of n is 2.
Now, m = 367
Applying process inversely,
First time,
(367 + 5) / 3 = 124
Second time,
(124+5)/3 = 43
Third time,
(43+5)/3 = 16
Fourth time,
(16+5)/3 = 7
m = 205
Applying process inversely,
First time,
(205+ 5) / 3 = 70
Second time,
(70+5)/3 = 25
Third time,
(25+5)/3 = 10
Fourth time,
(10+5)/3 = 5
m = 853
Applying process inversely,
First time,
(853+ 5) / 3 = 286
Second time,
(286+5)/3 = 97
Third time,
(97+5)/3 = 34
Fourth time,
(34+5)/3 = 13
m = 1339
Applying process inversely,
First time,
(1339+ 5) / 3 = 448
Second time,
(448+5)/3 = 151
Third time,
(151+5)/3 = 52
Fourth time,
(52+5)/3 = 19
We applied the process 4 times.
Therefore, the value of n is 4.

I don't understand this
plz answer 3,4 and 5
Answer:
3. Since it asked us to write question 3 in the from y=mx + c
m is the gradient
c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).
Now to find m.
Pick points on the line
Say (1,6) and (2,3)
Gradient = m = y2 - y1/(X2 - X1)
x1 = 1
y1 =6
x2 = 2
y2 = 3
Substituting into that formula
m = 3 - 6/2 - 1
m= -3/1
m= -3.
Since we've gotten what we need
y=mx + c
Y= -3x + 9.
4. 4x + 2y = 12
Rearranging by making y subject to suit the eqn...y=mx + c
you have
m is the gradient and c is the intercept.
2y = -4x + 12
Divide through by 2
y= -2x + 6
y=mx + c
By comparing...
m==gradient = -2
c== Intercept = 6
5). Doing the same thing we did above
-6x + 3y =21
Making y subject
3y = 6x + 21
Divide through by 3
y= 2x + 7
y=mx + c
m==gradient =2
c==Intercept =7.
Hope this helps.

Answer:
382 is the answer for the addition.
Step-by-step explanation:
you don't really need the side panel, however it seems it was included in the problem itself. however simply adding the first numbers together will give you the correct answer, and adding the 3 seperate numbers on the bottom will give you the same: 382.

Answer:
Yes, Fiona is correct
Step-by-step explanation:
WHen the pythagorean theorem is applied to the side lengths (2^2 + 4^2 = c^2), the result for c^2 is 20. The correct answer would be sqrt.20. But Fiona is also correct becuase sqrt of 20 can be simplified to sqrt.4 * sqrt.5; which equals 2*sqrt.5

Which of the following are needed to make an expression?
A. variable(s)
B. number(s)
C. equal sign
D. operation(s)
Answer:
variables is the correct answer
Answer:
ALL OF THE ABOVE
Step-by-step explanation:
An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.
It can be all of the above too. because everything is needed to make an expression.

What does the point (200,90) represent?
Answer:
It represents 20 every 9
Step-by-step explanation:
(200,90) The 200 is on the x axis (horizontal, hotdog style), the 90 is on the y axis (vertical). Take whatever you have written on the bottom of the x axis (like feet) and whatever you have on the y axis like (time) and put them together into a sentence. Something like - "after 90 minutes (time) the whatever u r talking about traveled 200 feet (distance.)" <--- THIS IS JUST AN EXAMPLE DO NOT USE THIS.
It is difficult to answer this question without more context. Check the axes and write your answer based on whatever they say.
Which equation represents a linear function?
A. y= 1/2 x to the second power - 5
B. y= 1/2 x to the third power - 5
C. y= 1/2 x + 5
D. y=(1/2) to a power - 5
Answer:
C. y = 1/2x + 5
Step-by-step explanation:
For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.
For D. it doesn't even have x in it, so basically y equals a number.
C. is a linear equation, y = 1/2x + 5
Which value is equivalent to the expression 2 to the 3rd power + 3 to the 4th power??

Step-by-step explanation:
2^3 + 3^4
