50/80 = 0.625
100 - 0.625 = 0.375
0.375 = 37.5% (move the decimal point to the right 2 spaces)
37.5% decrease is your answer
hope this helps
Choose number 2, it is divisible by 2,

but it is not divisible by 4, because

but

.
Answer:
The first one is the answer.
Step-by-step explanation:
It's an arithmetic sequence. It has a common difference.
d = an - a_n-1
an = -12x + 12
a_n-1 = - 7x + 8
d = -12x + 12 - (-7x + 8)
d = -12x + 12 + 7x - 8
d = -5x + 4
Try it. Let's try for the third term
-12x + 12 - 5x + 4
- 17x + 15 which is exactly what the third term is.
Yes it is the right answer. Nice job.
The range is the set of possible y values of a function. All you need to do is list off the y coordinates of the points shown. The points on the graph are
(1,2), (5,1), (6,3), (2,5)
in no particular order.
The y coordinates of those points are: {2, 1, 3, 5} which sorts to {1,2,3,5}

numbers one two and three are correct
