If x=-3/7 and y=-5/4,varify that |x+y|=|x| +|y| and |x*y| =|x|* |y| |
|
Answer» -step explanation:(X+y)=(-x)+(-y)-( \frac{ - 3}{4} ) + ( \frac{ - 6}{7} ) = ( - ( \frac{ - 3}{4} ) + ( - ( \frac{ - 6}{7} ))( 4−3 )+( 7−6 )=(−( 4−3 )+(−( 7−6 ))if the solution is EQUAL on both hand side than it is verifying |
