The complete question is
"Find the general solution of the given differential equation
y''-y=0, y1(t)=e^t , y2(t)=cosht
The function
is the solution of the given differential equation.
The function y(t)=cosht is the solution of given differential equation.
<h3>What is a function?</h3>
The function is a type of relation, or rule, that maps one input to specific single output.
Given;
![y_1(t) = e^t](https://tex.z-dn.net/?f=y_1%28t%29%20%3D%20e%5Et)
Given differential equations are,
y''-y = 0
So that,
Substitute values in the given differential equation.
![e^t -e^t=0](https://tex.z-dn.net/?f=e%5Et%20-e%5Et%3D0)
Therefore, the function
is the solution of the given differential equation.
Another function;
So that,
![y"(t)=sinht\\\\y"(t)=cosht](https://tex.z-dn.net/?f=y%22%28t%29%3Dsinht%5C%5C%5C%5Cy%22%28t%29%3Dcosht)
Hence, function y(t)=cosht is solution of given differential equation.

4y - (3+y) is standard form is: 3y - 3
Answer:
< 1 = 125 degrees
< 2 = 55 degrees
< 3 = 125 degrees
< 4 = 55 degrees
< 5 = 125 degrees
< 6 = 55 degrees
< 7 = 125 degrees (given)
< 8 = 55 degrees
Step-by-step explanation:
1 and 3 are equal because they are vertical angles, therefore proving their congruence.
7 and 1 are equal because they're alternate exterior angles, which are congruent.
2 and 4 are vertical, which is congruent.
5 and 7 are vertical.
6 and 8 are vertical.
