Answer:

<h2>y = 4.5</h2>

Step-by-step explanation:

\dfrac{15}{y}=\dfrac{40:4}{12:4}\\\\\dfrac{15}{y}=\dfrac{10}{3}\qquad\text{cross multiply}\\\\10y=(15)(3)\\\\10y=45\qquad\text{divide both sides by 10}\\\\\dfrac{10y}{10}=\dfrac{45}{10}\\\\y=4.5

Adding which of the following ordered pairs to the set [(0, 1), (2, 4), (3,5)) would make it not a function?
Kitty [74]

Answer:

(0,7)

Step-by-step explanation:

For a set of ordered pairs to be a function, there needs to be "ONE" value of y for each unique x value.

Thus, we see that the 3 ordered pairs given have x values of 0, 2, and 3.

Now, we look in the answer choices and find which ones are 0, 2, or 3 in x-coordinate.

That would be only (0,7). Now the original set has x = 0 corresponding to y = 1

Is that true for (0,7)?? NO!

x = 0 will now correspond to "TWO" values of y.

THis will make this NOT A FUNCTION.

So, (0,7) is correct.

40! When you add all four angles of a quadrilateral together, you will always end up with 360. So, 360-75-120-125=40 :) have a great day!
