Set the equation equal to y
Add x to each side
7y=14 +x
Divide each side by 7
y=2 + x
The slope is whatever number corresponds with the variable x
In this case there is no number in front of the x which indicates that the slope is 1
Answer:
(A) 
(B) 
Step-by-step explanation:
We have to find the Laplace transform
(a) x(t) + 7 x(t) = 5 cos2t
Taking Laplace of both side



(B) 
Taking Laplace transform of both side



Answer:
x = 9º
∠B = 40º
Step-by-step explanation:
5x-5º = 3x+13º
<em>[add 5 to both sides]</em>
5x = 3x+18º
<em>[subtract 3x from both sides]</em>
2x = 18º
<em>[divide each side by 2]</em>
x = 9º

3x+13º = 3(9º)+13º=27º+13º = 40º
