There are 5 letters in the word "prime"
Imagine we had 5 slots to fill. They are empty initially.
Slot 1 has 5 choices to pick from
Once we pick a letter, we have 4 choices left over for slot 2
Slot 3 will have 3 choices
Slot 4 will have 2 choices
Slot 5 will have 1 choice
We have this countdown: 5,4,3,2,1
which multiplies out to 5*4*3*2*1 = 120
There are 120 unique ways to arrange the letters. Order matters. Because order matters, this is a permutation.
The correct answer is
Inequality: n>-10
Interval Notation: (-10,infinity)
Hi there!
Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.
Step 1) Add 8y to both sides.
Step 2) Divide both sides by 6.
Final Answer -
Hope this helps! :D
