The answer is -1 because when cross simplifying you get 0/2-2/0 which =-2/2 and that simplified is -1
The answer is -1
Answer:
90720 ways
Step-by-step explanation:
Since there are 9 letters, there are 9! ways to arrange them. However since there are repeating letters, we have to divide to remove the duplicates accordingly. There are 2 ‘s’ and 2 ‘i’ hence:
Number of way to arrange ‘dissipate’ = 9! / (2! x 2!) = 90720 ways
Hence there are 90720 ways to have the number of dissipate in the letter.
Answer:
The closed linear form of the given sequence is 
Step-by-step explanation:
Given that the first term
and 
To find the closed linear form for the given sequence
The formula for arithmetic sequence is
(where d is the common difference)
The above equation is of the given form 
Comparing this we get d=0.75
With
and d=0.75
We can substitute these values in



Rewritting as below

Therefore 
Therefore the closed linear form of the given sequence is 
Answer:
yes this is a function
Step-by-step explanation:
simple method to find if something is a function
if you can draw a vertical line at any point on the graph and get two intersections, it is not a function
Answer:
D 21
Step-by-step explanation: x/7 = 3
isolate x by multiplyig both sides by 7: (7)(x/7) = (3)(7)
x = 21
