Answer:
f(n) = a+200(n -1)
Step-by-step explanation:
The constant difference between terms indicates the sequence is an arithmetic one. The explicit formula for an arithmetic sequence is ...
an = a1 + d(n -1)
where a1 is the first term and d is the common difference.
Your first term is "a", and your common difference is 200, so the n-th term of the sequence is ...
an = a + 200(n -1)
Written as a function of n, this is ...
f(n) = a + 200(n -1)
_____
Based on the problem description, we cannot tell how n relates to time, so we have created an f(n) that gives the same result as the recursive definition of f(n).
4x + y = 12
Get y by itself
Subtract 4x
y = -4x + 12
Since you know what y is, you can plug the value into the second equation
6x + 2(-4x + 12) = 18
6x - 8x + 24 = 18
-2x = -6
x = 3
Plug the value 3 into x for y = -4x + 12 in order to find y
-4(3) + 12 = y, y = 0
Solution: x = 3, y = 0

Answer:
3/4
Step-by-step explanation:
2/3 = 4/6 so 5/6 plus 4/6 = 1 3/6 then divide by 2, it will give u 0.75 in decimal form which is simplifyed to 3/4, so 3/4 is the answer.
