Radda [10]

Answer:

It's gonna be 12 servings of 1 1/2 cups in 18 cups.

Step-by-step explanation:

1.5+1.5+1.5+1.5+1.5+1.5+1.5+1.5+1.5+1.5+1.5+1.5=

you have 12 whole 1's, so there's 12. Plus, 12 .5's so add all of the halves together.

.5+.5=1+.5+.5=2+.5+.5=3+.5+.5=4+.5+.5=5+.5+.5=6.

So, now you have 6. You add the 6 to the 12, and now you have 18.

So, 12 servings of 1 1/2 or 1.5 is 18 cups.

Hope this helps you! (:

Which of the following rational functions is graphed below
Rudik [331]

Answer:

D

Step-by-step explanation:

This graph shows two vertical asymptotes, one at x = +3, the other at x = 4.  Thus, we omit the first two answer choices.  Next, we substitute 0 for x and determine the y value in Answer Choice C:  F(0) = 0.  Does the graph go through (0, 0)?  Yes, it does.  Next, evaluate F at x = 3.5 (halfway between x =  3 and x = 4); that is, evaluate function D at x = 3.5.  Does the y value come out to be -4 as shown in the graph?  Yes, it does.    So D is the correct function to match this graph.
