A system of equations is shown. y = 2x - 7
y = -x + 5
What is the solution to the system of equations?

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
