The system ⎧⎩⎨a2+b2−c2=05a−b=ca+b+c=30 has exactly one solution. find the solution by using substitution. enter your answer as an ordered triple in the format (a, b, c), like this: (42, 53, 64)

(5,12,13)

Step-by-step explanation:

You are given the system of three equations

The second equation states that

Substitute it into the first and third equations:

From the last equation

Substitute it into the first equation

Then

The solution is (5,12,13)

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
