Assume a solution of the form 
. Taking the differential of both sides would give the ODE
where 
and 
. The ODE is exact if 
. We have
so the ODE is not exact. However, multiplying both sides by 
gives
and now
so the ODE is now exact.
Now,
So the ODE has solution
or simply
Answer:
25 units
Step-by-step explanation:
Distance Formula: 
Our points: (0, 0) and (7, -24)
d = √(49+576)
d = √625
d = 25
SO, first you divide the numerator by the denominator.
Then write it like this:
From the first inequality x > 2 - 3 so x> -1
and from the second:- x <= 4
so the graph will be a number line with an open circle at x = -1 and a closed circle at x = 4 and the line is shaded in between.
The angle is the arctangent of the ratio of ay to ax. Since ay is negative and ax is positive, it is a 4th-quadrant angle.
... arctan(ay/ax) = arctan(-4.00/3.90) ≈ 314.27°
... about 5.48513 radians
