Mary was allowed a discount of 11% for goods worth sh.8000 and a discount of 8.6% for goods worth sh.17000. What percentage discount was she allowed altogether ​

11%+8.6=19.6%

Step-by-step explanation:

this question means that they wanted the total percentage discount that Mary was allowed.so I got the total percentage discount by adding both percentage discounts to get to get the total percentage discount she was allowed to gether I guess this helps.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

the infinity sign
