Answer:
3/5
Step-by-step explanation:
The formula for inverse variation is y = k/x.
We are to find k by subbing -6 for y and -2 for x: -6 = k(-2), or k = 3.
So, we have the inverse relationship y = 3/x.
Now, if x = 5, y = 3/5.

Answer:
7 : 9
Step-by-step explanation:
Let the first mat has a length of the sides 7x, 7y, and 7z and the second mat has a length of the sides 9x, 9y and 9z.
{Since the scale factor of the two triangular mats is }
Hence, the perimeter of the first mat will be (7x + 7y + 7z) and the perimeter of the second mat will be (9x + 9y + 9z).
Therefore, the ratio of the perimeters of the two mats will be (7x + 7y + 7z) : (9x + 9y + 9z) = 7(x + y + z) : 9(x + y + z) = 7 : 9. (Answer)
Answer:
angle A + angle B = 180 degrees is correct
Step-by-step explanation:
Answer:
Only the second one represent a function because the x does not repeat.
For the first and last functions the x is repeating; therefore they are not functions.
