Answer:
<em>Explanation to the answer below... (Answers in the Explanation</em><em>)</em>
Step-by-step explanation:
We Know that our rule is y = 
, which means we can use this rule to find y from x. Since we don't know what X, is, we have to assume numbers like 1, to 7. And there is no space to write on the graph, I'll put a virtual copy of a graph.
1st Point,
2nd, point
3rd Point
4th Point
5th Point
6th Point
7th Point (Last Point)
Let's now plot them on the Graph, the values are so big, the graph might look a little odd.
Always remember that we can continue the points infinitely, and there is no stop, The Graph is attached below...
Answer:
EACH TIE COSTS 7.43
Step-by-step explanation:
If 13.35x13=173.55 then that means the ties total is 189.46 now devide that by 22 it equals 13.35
Let the two numbers are x and y
Let larger number = x
and smaller number = y
it means
x-y = 0.77
Now it says larger number is increased 5 times
So it now becomes 5x
So second equation becomes
5x -y =77
Now we have to solve these two equations
x-y = 0.77 and 5x-y = 77
multiply first equation by -1 and then add both equations
-x+y = -0.77
Now on adding we get
-x+5x +y -y = 77-0.77
4x = 76.23
Divide both sides by 4
x=19.0575
We get the larger number , now subtract 0.77 from this , we will get the smaller number
y=19.0575-0.77=18.2875
y=18.2875
Hence the larger number = 19.0575
Smaller number = 18.2875
Answer:
(b) √5
Step-by-step explanation:
The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...
The integer 5 is not on that list, so its square root will be irrational.
√5 is irrational
