Answer:
4
Step-by-step explanation:
15x+20 = 40 +10x
x = 4
Starting amount : 650
charge per week : 20 bucks
∆= 180°
180°-(62°+58°)= ?
180°-120°=60°
a line = 180° on both sides.
180°-60°=X
120°=X
Answer:
(-3, 1)
The solution is the point at which both lines intersect.
This is the solution since both lines would have that point and only that ppoint in this type of problem. IN a graph where 2 lines are parralel, there is no solution as they never intersect . on a graph where the 2 lines overlap there is infinite solutions. FInally in a graph like this there is exactly one solution and it is the intersection of both lines
Step-by-step explanation:
If 
and 
, separate variables in the differential equation to get
Integrate both sides:
Use the initial condition to solve for 
:
Then the particular solution to the initial value problem is
(A)
