Answer:
11 is the common difference of the given sequence.
Step-by-step explanation:
Here the given sequence is
Terms 1 2 3 4
Sequence -12 -1 10 21
Now we know the arithmetic sequence is -12, -1, 10, 21.........n terms
common difference of an arithmetic sequence is represented as difference of nth term and (n-1)th term.
Therefore common difference d = -1 - (-12) = -1 +12 = 11
common difference 11 is the right answer.
Answer:C
Step-by-step explanation:
Area = 1/2 b h
Area = 1/2 * 9 * 9 = 40.5 sq cm
It would be the first graph because 150/5 is 30, so the boat costs $30 per hour as shown.
Answer: B-A
Step-by-step explanation:
We know that it is -A - (-B)
The negative sign on the A stays as it is, eliminating choices A-B and A+B.
For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.
Therefore, the answer is -A+B, or B-A. Hope it helps!
