Answer:

Yes, set K is a function.

Step-by-step explanation:

Given K = {(x, y) | x - y = 5}

we have to find is above set is a function or not.

Functions are relations that give one output for each input, or one x- value gives only one value of y.

As, x-y=5

⇒ y=x-5

The above set is a function because every x-value produces a different y-value i.e K satisfies the definition of what it meant for a relation to be  function.

Hence, set K is a function.

Which of the following statements is true according to the measurements in the diagram?
e-lub [12.9K]

Let's look at the corresponding ratios:

\frac{AB}{ED}=\frac{24}{30}=\frac{4}{5}\\\frac{BC}{DC}=\frac{16}{20}=\frac{4}{5}\\\frac{AC}{EC}=\frac{21}{28}=\frac{3}{4}\\

And we see that the three aren't equal.

Hence, $\Delta ABC$ and $\Delta EDC$ are not similar.
