The first song performed during a concert was more than 60 seconds longer than the final song. The first song was 190 seconds lo
ng. The inequality 190 > 60 + f represents the situation when f is the length of the final song, in seconds. f is in the center of a line. Which value should point f on the number line be?
1. 250
2. 190
3. 130
Which best describes the appearance of the graph?
1. open circle at f, shaded right
2. open circle at f, shaded left
3. closed circle at f, shaded right
4. closed circle at f , shaded left

Answer:
Step-by-step explanation:
So first, let's get rid of the parentheses. We can multiply it out to get . We know that the square root of 16 is ±4, so now our equation is ±4 -
=11. I'm guessing since the problem only has one solution it's most likely only positive 4, so let's revise our equation to 4 -
=11. We can use inverse operations to make the a little easier to solve: -7=
. We divide both sides by
to get
, which we can rationalize (remove the square root from the denominator so that it's a proper answer) by multiplying by
(which is equal to one so we can use it) which is equal to
. Let's finish this by simplifying it.
(2x
). We can simplify it further by simplifying the 2, making it
.
Hope this wasn't too confusing! I'll answer any questions.
