Solve this system.
The sum of a two digit number and the number obtained by interchanging the digits is 154.If the tens digit number is 2 more than units digit number find the original number.
If plane A flew 30 minutes, plane B also flew 30 minutes.
30min = 0.5h
240km/h * 0.5h = 120km
10min = 1/6h
240km/h * 1/6h = 40km
120km + 40km + 20km = 180km

A circle passes through the points (-2,0), (2,0), and (3,2). Find the center of the circle. Enter your answer as an ordered pair.
In the diagram, the four points have coordinates A(0,1), B(1,3), C(5,2), and D(4,0). What is the area of quadrilateral ABCD?
y = mx + b
m = (10 -1)/(5 - 2) = 9/3 = 3
(2,1)
1 = 3*2 + b
b = -5
y = 3x - 5
