8 goes with 3/5: 10 goes with n (n being the number of cups)
Use cross products and we get 8n = 6
Now divide by 8
<u>8n</u> = <u>6
</u><u />8 8
n= 6/8 or 3/4 of a cup of flour.

The value of x when y = 2 is x = 36
Step-by-step explanation:
The equation that we have in this problem is:
In order to find the value of x when y is equal to
y = 2
We need to re-arrange the equation making x the subject.
We proceed as follows:
1) We add +7 on both sides:
2) Now we multiply both sides by 4:
3) Now we can substitute y = 2 and find the value of x:

So there is a hole or an asymptote at x = 3 and x = -1 and we know, that answer B) is wrong.
2. Asymptotes:
We have only one asymptote at x = -1 (and hole at x = 3), thus the correct answer is A)
