Answer:
The explicit formula is 15 + (n-1) -4
Step-by-step explanation:
The formula for an explicit formula is an = First number of the sequence (15) + (n-1)(times the amount of integers separating two different sequential numbers) which is -4.
For instance, since 15 is the first number, it will be a1 or 15. Next will be + (n-1) which is the same for every explicit sequence and the multiplier will be the difference between each number, which is -4 in the recursive sequence. As a result, the answer is 15 + (n-1) -4.
Answer:
(1, 2) and (-1, -2)
Step-by-step explanation:
Since y = 2x, the first blank tells you
2x = 2
x = 1
____
Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.
Answer:
40 degrees, 60 degrees, and 80 degrees
Step-by-step explanation:
2+3+4=9
180/9=20
20*2= 40
20*3 = 60 and
20*4=80
y = mx + b, where b is the y intercept.
D, or "12" is the answer.
Best of luck.
