Y is inversely proportional to x. If y= 400 when x =2 find y when x= 200
1 answer:
Answer: 4
<u>Step-by-step explanation:</u>
Inversely proportional means xy = k, where k is the constant of proportionality
First, find k when x = 2 and y = 400 ----> 2(400) = k --> 800 = k
Then, find y when x = 200 (knowing that k = 800)
200y = 800
y = 4

The answer is D. y = 1/2(x+2)^2 -3
Step-by-step explanation:
I just put each answer choice into a graphing calculator and chose the one that was equivalent, D. came out to be right
X - y = 3
x + y = 13
Adding both equations
2x = 16
x = 8
y = 5
What equation are you suppose to solve in your question?
