Hey i was wondering can i move +7 from inside the absolute value in the left side to -7 outside the absolute value on the right
side? for example in the question below is the answer right is the answer zero ?
2 answers:
The statement is false for any value of x because the absolute value function is always positive or 0.

Answer:
<u>Skills needed: Angle Geometry</u>
Step-by-step explanation:
1) First, let's see what we should know prior to solving.
---> We have to find the value of , and looking at that diagram, we have to create an equation.
---> The angle measure of a straight line is 180 degrees, otherwise known as a straight angle (a straight angle is 180 degrees).
---> When you add , you can set that sum equal to 180. This is because the two angles marked
added together make a straight line, which is a straight angle.
(Note: In geometry, ONE OF THE THINGS WE CAN ASSUME is that there is a straight line there.)
-------------------------------------------------------------------------------------------------------------
2) Now, the equation would be:
--> Combining
and
(3+3 = 6)
--> Dividing by 6 on both sides, to get
by itself.
--->
is 30, so
is equal to 30.

The request is to find the intersection of the two sets. By definition, the intersection of two sets is another set, composed by all the elements appearing in both sets.
In other words, is the set of all elements that P and Q have in common.
P contains all the numbers from 0 to 9, V contains all the odd numbers between 1 and 19. So, their intersection will be the odd numbers between 0 and 9, i.e.
