Answer:
E) x=0 or y=-5
Step-by-step explanation:
The slope field will have vertical segments when dy/dx is undefined, that is, dy/dx is a division by 0.
We have that
dy/dx=(3y)/(xy+5x)
So the slope field will have vertical segments when
This is when x = 0 or y = -5.
So the correct answer is:
E) x=0 or y=-5
Answer:
x = 11
Step-by-step explanation:
Using Secants ad Segments Theorem we can say;
(x + 7) (7) = (15 + 6) (6)
7x + 49 = (21) (6)
7x + 49 = 126
7x = 77
x = 11

Answer:
20/3 ounces of water is added.
Step-by-step explanation:
how many ounces of pure water should be added to 20 ounces of 40% solution of muriatic acid to obtain a 30% solution of muriatic acid?
--------------
The acid is 40% of 20 ounces = 8 ounces.
0.4*20 = 8
----------
That same 8 ounces is to be 30%. The water will be the other 70%.
8/30 = x/100
30x = 800
x = 80/3, the total amount of the solution.
We started with 20, so 80/3 - 20 = 20/3
20/3 ounces of water is added.
