Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
Answer:97.1

Answer:
X = 36/17
y = -8/17
Step-by-step explanation:
Since they both equal y, you could use them equal to each other.
(5/2)x-4=(-1/3)x+2
Then solve for x by combining like terms. X should be 36/17. Plug in x to find y in one of the equations. I will use the top one. (5/3)(36/17)-4=y. That should simplify down to (60/17)-4=y. Y would finally equal -(8/17).
Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
