How do you do this question?
stealth61 [152]

Answer:

E

Step-by-step explanation:

dy/dt = y² − 1

When -1 < y < 1, dy/dt is negative.  So the solution is decreasing between y = -1 and y = 1.

Only one graph is consistently decreasing in that range, and that's the last graph.

Using the quadratic formula to solve x? + 20 = 2x, what are the values of x?
Sergio [31]
I am not sure if the “+” was supposed to go there or if that was just a typo, so I do apologize if this is wrong... but if it doesn’t belong in the equation at all, 20 = 2X is a fairly simply multiplication problem. You are to divide both sides by the 2 and you should get X = 10, because 2 goes into 20, 10 times; and the 2 goes into 2 only once, therefore the 2 now gets cancelled out.

Answer: 20 divided by 2 = 2x divided by 2 is now 10 = X.

Really hope this helps you, have a good day :)
