Answer:
The constant of variation is k = -2 ⇒ (B)
Step-by-step explanation:
The equation of the direct variation is y = k x, where
- k is the constant of variation
- The constant of variation k =
![\frac{y}{x}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D)
The given table has 4 points (-1, 2), (0, 0), (2, -4), (5, -10)
We can use one of the points <em>[except point (0, 0)]</em> to find the value of k
∵ (-1, 2) is a given point
∴ x = -1 and y = 2
∵ k = ![\frac{y}{x}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D)
→ Substitute the values of x and y in the relation above
∴ k = ![\frac{2}{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B-1%7D)
∴ k = -2
The constant of variation is k = -2
Answer:
c
Step-by-step explanation:
Answer:
Step-by-step explanation:
=4/7-3/7
=4-3/7
=1/7
Lets find out...
a^2 + b^2 = c^2
27^2 + 79^2 = 84^2
729 + 6241 = 7056
6970 = 7056....incorrect....no, it is NOT a right triangle
Answer:
36
Step-by-step explanation:
Divide 108 by 3 to get your answer, since the denomintors are the same.
103/3 = 36
