Answer: True
Step-by-step explanation:
Inverse variation means y=k/x (direct variation is y=kx)
You are given a point, so you can solve for the constant k...
2=k/15
k=30 so the function is:
y=30/x
Answer:
Step-by-step explanation:
Method
The smallest the third side can be is something just larger than 2
You get 2 by subtracting10 and 8. The third side is just a bit larger. 8 and 2 will make up the length of 10 so you cannot use 2 itself
The largest value possible is just under 18. You get 18 by adding 8 and 10 together. So to get a triangle, you need just under 18.
Answer
2<s<18
A
For this equation, you simply plug in the number 5 every time you see an n. So T(5)=5-7, which equals -2
