Question 961826: Ive been given a test and i have one question wrong. I dont know how to solve it, but i have the correct answer, and i seriously do not get whet to do. The question is:
"if y varies inversely as x and y= 194 when x= -13, find y when x=50. round your answer to the nearest hundredth if necessary."

You can put this solution on YOUR website!
"if y varies inversely as x and y= 194 when x= -13, find y when x=50. round your answer to the nearest hundredth if necessary."
:
"if y varies inversely as x"
y = 1%2Fx
:
and y= 194 when x= -13, find y when x=50. round your answer to the nearest hundredth if necessary."
We can write a ratio equation for inverse relationships
y1%2Fy2 = x2%2Fx1
x1=-13, y1=194
x2=50; y2= ?
:
194%2Fy2 = 50%2F%28-13%29
crosss multiply
50*y2 = 194 * -13
y2 = %28-2522%29%2F50
y2 = -50.44
