Answer:
For the First one, 2 + 9 = 11. And 11 - 3 + (-19) = -11
Step-by-step explanation:
This expression is a perfect square trinomial. It has two answers but they don't have to be different. In this case it has to be the same - because it is a perfect square trinomial.
The answer is B. It’s not too difficult
Answer:
Top left
Step-by-step explanation:
In order for it to be a function, it has to pass the vertical line test. So draw a line down the middle of the graphs. If it passes once, then it is a function, if it passes more than once it is not.
Given the differential equation

The solution is as follows:
