Answer:
(-4,8)
Step-by-step explanation:
solved with substitution method.
D.6x^2+3x+3, to find your answer combine like terms. ex: x^2 and 5x^2 have ^2 in common so combine to get 6x^2.
1. Correct answer is a (since when you are not given the n values, it is implied that the first value is 1).
3. Correct answer is a (a(n)=-3+4(1-1)=-3).
7. The pattern is to reduce the previous value by 4, thus the 12th term of the sequence is -24 (a(n)=20 - 4(n-1)=20 - 4(12-1)=-24).
8. Missing term is 26 (32+20=52; 52/2=26).
10. Pattern is 625/1=625; 625/5=125; 125/5=25; 25/5=5, thus. the 10th term is 1/3125 (answer a).
The correct answer is B) $3,250, because if you add up the numbers consecutively you get that.
