Acruise ship travel 12 miles due north. then 16 miles due east. how far is the ship from where it started? (do pythagorean theorem)

A^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
find the square root of 400
c = 20 miles

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
