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 =
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 =
→ Substitute the values of x and y in the relation above
∴ k = 
∴ k = -2
The constant of variation is k = -2
Answer:
Yes for 1st and 4th, No for the 2nd, 3rd and 5th.
Step-by-step explanation:
You need to plug the first number in each set of brackets into x and the second number into y. The first equation asks if y is the greater than -x. The only ones this is true for are the 1st, 3rd, and 4th answers, so the 2nd and 5th are no. Now check the 1st, 3rd and 4th to see if the answer is less than or equal to 2 when plugging in x and y. This is true for the 1st and 4th answers, so move those to yes and the 3rd to no.
Answer: Yes for 1st and 4th, No for the 2nd, 3rd and 5th.
Answer:
if a is perpendicular to b then four 90 degree angles are formed
Step-by-step explanation:
if a line is perpendicular to another that means that it forms a 90 degree angle on all of the angles
