F(1) is saying the value of x is 1
Look at the graph where x is 1 and find the y value of where the line is.
At x = 1, the line is at y = 1 ( there is actually a dot showing you the location.
The answer is 1
Answer:
It is not arithmetic, so therefore there is no common difference
Step-by-step explanation:
An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. There is no constant term in the above pattern.
Answer:
Step-by-step explanation:
-3.1+7-7.4x=1.5x-6(x-1.5)
We move all terms to the left:
-3.1+7-7.4x-(1.5x-6(x-1.5))=0
We add all the numbers together, and all the variables
-7.4x-(1.5x-6(x-1.5))+3.9=0
We calculate terms in parentheses: -(1.5x-6(x-1.5)), so:
1.5x-6(x-1.5)
We multiply parentheses
1.5x-6x+9
We add all the numbers together, and all the variables
-4.5x+9
Back to the equation:
-(-4.5x+9)
We get rid of parentheses
-7.4x+4.5x-9+3.9=0
We add all the numbers together, and all the variables
-2.9x-5.1=0
We move all terms containing x to the left, all other terms to the right
-2.9x=5.1
x=5.1/-2.9
x=-1+1/1.31818181818
THIS IS UR ANSWER... THANK YOUU
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
