Ordered pairs that work for this direct variation are (4, 3), (8, 6) and (12, 9).
In order to find these, we must first find the value of the direct variation coefficient. We can do that using the base equation y = kx and then by plugging in to find k.
y = kx
12 = k(16)
3/4 = k
Now that we have k, we can model the equation as y = 3/4x. We can also find any number of ordered pairs by using the x value and finding the y value. All of the above answers work.
Answer:
11<em>i</em>
Step-by-step explanation:
first you have to get a postive root.
then you solve the square roots from there, keeping in mind the imaginary number answer to the square root of -1, <em>i</em>.
0.64,-3.14 I’m not really sure about the -3.14. (Sorry).
The domain is {0≤x≤200}.
This is because the domain is x, the number of cakes. The smallest number of cakes she can bake is 0.
Since she is buying enough materials to make 200 cakes, this number is the largest number of cakes she can bake.
