This answer needs to be rounded to the nearest hundredth. Example:12.34

lara [203]

Answer is 14.14
Reason
Using Pythagorean theory
a^2 + b^2 = c^2
The two legs are a and b, the longest diagonal opposite the right angle is c
10^2 + 10^2 = c^2
200 = c^2
Take square root of both sides
14.14 = c

Which of the following statements best describes the graph of x + y = 4?

vaieri [72.5K]

The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4

The second one gives a point of (4,0)

The third one is nonsense. (4,4) is not on this line.
