The so-called pythagorean triple will just be the distance between both points,

To find y-intercepts, you substitute in 0 for X
2y-5x=16
2y-5(0)=16
2y-0=16
2y=16
Y=8
So the y-intercept is (0,8)
The new cost would be 19.55.
Explanation: 1. 23 * 0.15 = 3.45
2. 23 - 3.45= 19.55
Answer:
8 ft
Step-by-step explanation:
Set up a proportion: 10/16=5/x
Solve for x: 80=10x
x=8
