1. y=6
2. y=-12
Step-by-step explanation:
<u>1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.</u>
It is given that
y varies inversely as x
IT will be written as:
y∝1/x
Removing the proportionality symbol
y=k/x
Given
y=3 , x=-2
Putting the values
3=k/-2
k=3*-2 = -6
The equation will be:
y=-6/x
So,
When x=-1
![y=\frac{-6}{-1}\\y=6](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-6%7D%7B-1%7D%5C%5Cy%3D6)
<u>2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4</u>
y is directly proportional to x
y∝x
y=kx
Given
y=15, x=-3
Putting the values
![y=kx\\15=-3k\\k=\frac{15}{-3}\\k=-5\\The\ equation\ will\ be:\\y=-3xNow,\\x=4\\y=-3(4)\\y=-12](https://tex.z-dn.net/?f=y%3Dkx%5C%5C15%3D-3k%5C%5Ck%3D%5Cfrac%7B15%7D%7B-3%7D%5C%5Ck%3D-5%5C%5CThe%5C%20equation%5C%20will%5C%20be%3A%5C%5Cy%3D-3xNow%2C%5C%5Cx%3D4%5C%5Cy%3D-3%284%29%5C%5Cy%3D-12)
Hence,
1. y=6
2. y=-12

Hi!
It doubles in size, it says 6 wool cards for 3 ore cards, that's twice as much, so then for 4 ore cards Jillian needs to trade 8 wool cards.
Hope this helps!
