The variables x and y vary inversely, and x = 12 when y = 6. Use the inverse variation formula, k = xy, to find y when x = 3.
1 answer:
Answer:
24
Step-by-step explanation:
xy = k
Filling in given values, we have ...
12·6 = k = 3·y
y = 12·6/3 = 24
y is 24 when x is 3.

Answer:
x = 8
Step-by-step explanation:
AN = NC,
4x - 7 = 5x -15,
-7 = x -15,
8 = x
Here is your answer
a) 5x-2y= 1
REASON:
6-2(x-y)=3x+5
6-2x+2y= 3x+5
3x+2x-2y= 6-5
5x-2y= 1

-1 or option c is correct. Use the given functions to set up and simplify f(−2).
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
