You should first find out what lines are what,
Like for example, If you had 5 - 10 - 15 as the Y Lines and the bar was between 5 and 10 then your best bet would be to estimate what the middle of 5 and 10 is which would be 7 or 8.
For question 6 the answer is 100 because a quarter of a circle is 90 degrees
The correct answer to this question would be B)
this is because there are some sides that are longer than others
By definition, if
is the least upper bound of the set
, it means two thing:
In other words, the least upper bound of a set is greater than or equal to every single element of the set, but it is "close enough" to the elements of the set, because you guaranteed to find elements in the set between
and 
For example, pick
. Obvisouly, the least upper bound is
. In fact, every number in
is smaller than 10, but as soon as you take away something from 10, say 0.01, you get 9.99, and there are elements in
greater than 9.99, say 9.9999.
So, the claim is basically proven by definition: if
, let
. By definition, there exists
.
Answer:
No solution
Step-by-step explanation:
7x - 3 = 7 + 7x
Subtract 7x from both sides of the equation.
7
x
−3−7x=7 rewrite as
7x-7x-3=7
-3=7
