Answer:
In the given expression the constant of proportionality is k = 8.
Step-by-step explanation:
The quantity P is said to be directly proportional to Q if they vary in proportion to each other.
Here, P ∝ Q ⇔ P = kQ : k = Proportionality Constant
Now, here given y ∝ x and x = -2, y = -16
Now, y ∝ x ⇒ y = kx
or, (-16) = k (-2)
or, k = 16/2 = 8
⇒ k = 8
So, for k = 8, y ∝ x
Hence, in the given expression the constant of proportionality is k = 8.
Answer:
336 purple tiles
Step-by-step explanation:
384 in all
6 times 8 is 48 so u subtract 48 by 384 and get 336
To prove the circles (or any polygon) are similar you need to establish a proportion between them that is multiplied or divided. Scale factors are products not sums, so A is out. We aren't translating, so B is out. We aren't flipping, so D is out.
Thus, the third choice of using a scale factor is best.
