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
The exact answer is 12 root 2, but you can also say approximately 17.
I got this by finding the square root of 369, and then 81. After finding these values, you get the equation...
a^2 + 9^2 = 369
a^2 + 81 = 369
a^2 = 288
And then I just found the square root of 288
Answer:
8(x/2) + 8(3/8) = 1(8)
8(x/2)..the two cancels out and you are left with 4x
8(3/8)..the 8 cancels and leaves with 3
1(8)=8
4x+3=8
Subtract the 3 from both sides to get the x term alone
4x=5
Divide both sides by x to get alone
x=5/4
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
y = 15 - 3x
0 = 15 - 3x
15 - 0 = 3x
x = 5
AB = 12
BC = 5
AC = 3
To find AC, we can use the pythagoras theorem, square root of 12 power of 2 + 5 power of 2 and we can get 12. Hope this help!
