Answer:
Yes , it is separable
Step-by-step explanation:
We are given that DE
We have to find the the given DE is separable or not.
When the DE is separable then it can be written as
Given DE is in Separable form.Therefore, it is separable.
Answer:
6
Step-by-step explanation:
so simply look at the you know that (ax)(4x)=4a*
= 24
,
4a = 24 => a = 6
Done.
Remark
The very first thing you should do with a question like this is get the graph. Then you will know what you are looking for. I have provided you with such a graph. Your table should center around -2 ≤ x ≤ -1
So let's set up a table and see what we get. Start with y = x + 5
x x + 5
-1 4
-1.25 3.75
-1.5 3.5
-1.75 3.25
-2 3
Do the same thing for - (3)^x + 4 See below to see how this is entered your calculator
x -(3)^x + 4
-1 3.66
-1.25 3.75
-1.5 3.8
-1.75 3.85
-2 3.89
Conclusion
When x = - 1.25 y = 3.75 for both graphs. <<<< Answer

You may not be familiar with how to put this in your calculator. This is the way I would do it. I'm only doing it for y = -(3^x) + 4
Let x = - 1.25
