constant of variation k = 10 when y=12 and x = 1.2
Step-by-step explanation:
We are given If y varies directly as x, and y is 12 when x is 1.2, what is the constant of variation for this relation?
y = 12
x = 1.2
Constant of variation = k = ?
We know that if y varies directly as x then:
We need to find k:
Putting values:
So, constant of variation k = 10 when y=12 and x = 1.2

Answer:
D
Step-by-step explanation:
Let's see if the lengths of these two segments are the same or not. We will use the distance formula, which says that for two points and , the distance between them is: .
For AB, is (-9, 12) and is (3, -6). So, the distance is:
For A'B', is (-3, 4) and is (1, -2). So, the distance is:
We can see that is 3 times of , which means that AB (the original) is 3 times the length of A'B' (the transformed).
Since the length has changed, we know that it must be some sort of dilation because that's the only kind of transformation that will change the length. We see that the segment has also shortened, which means that its scale factor must be less than 1.
The only answer that matches is D.
Hope this helps!
Answer:
Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph. The easiest way to think of them is if you drew more than one function on a graph, and you just erased parts of the functions where they aren’t supposed to be (along the ’s); they are defined differently for different intervals of . So is defined differently for different values of ; we use the to look up what interval it’s in, so we can find out what the is supposed to be. Note that there is an e…
