string flying 40m vertically above the ground.

Consider the system: y = 3x + 5 y = ax + b what values for a and b make the system inconsistent? what values for a and b make the system consistent and dependent? explain

1) prove that 731^3−631^3 is divisible by 100 2) prove that 99^3−74^3 is divisible by 25
