Answer: 
Step-by-step explanation:
1. To simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.
2. Keeping this property on mind you have, you can rewrite the expression as following and simplify:
Answer: y = 0.4x
In fraction form, this is y = (2/5)x
================================================
Explanation:
For each row, divide the y over x values
- Row One: y/x = 0.8/2 = 0.4
- Row Two: y/x = 4/10 = 0.4
- Row Three: y/x = 6/15 = 0.4
- Row Four: y/x = 10/25 = 0.4
We end up with the same thing each time.
Since y/x = 0.4, this rearranges to y = 0.4x
Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

Answer:
2nd option
Step-by-step explanation:
using the converse of Pyhagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 100 , then 100² = 10000
60² + 80² = 3600 + 6400 = 10000
then
60² + 80² = 100²
thus the triangle is right
