Answer:
X would be equal to 5.
Step-by-step explanation:
20 divided by 16 equals 1.25.
1.25 times 4 equals to 5.
let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.
cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.

8 = 4 + 2c
move 4 to the other side
the sign always changes when moving to the other side
8-4= 4-4+2c
8-4= 2c
4= 2c
divide both sides by 2 to get c by itself
4/2= 2c/2
Cross out 2 and 2 divide by 2 and then becomes 1*1*c= c
c= 4/2
Answer: c= 2

Done!!
Particular solution

I believe that y'(0) = 4, not y(0) anymore. Since y(0) CANNOT have two different solution.


The last step is to put C1, C2 into your solution. You finish it.
Sixty seven and seven tenths
method: take twelve and six tenths away from sixty five and eight tenths to get fifty five and a tenth then add twelve and six tenths to fifty five and a tenth
