So when you have a -(-) then you make that a positive so that would mean - (+) so the two - - are positive and just one - is still negative, which would mean that the answer is -3. Because if the negative is greater that the positive then it is still a negative, in your mind you should make 13 positive minus 10 and then add the negative to make things easier if you want to.
To formulate an equation to represent this, you must simply break apart each section and understand it. The equation is
10(1/2x+6)=9
We can get the "10" because it says "10 times the."
The "1/2x" because it says "half a number"
You will find the "+6" because it said "the sum of half a number and 6"
Is will almost always mean equals, as with this case. Therefore, because it says "is 9" we know it equals 9.
Answer:
A positive correlation is a relationship between two variables in which both variables move in tandem (the same direction)
The perimeter is 11.12.
We use the distance formula to find the length of each segment that makes up the quadrilateral:
For RS:
For ST:
For TU:
For UR:
This gives us a perimeter of 2+3+2+4.12 = 11.12
