Answer: A is 36.82%. B is 35.5%
Step-by-step explanation: For manufacturer A 22/19 chian discount simply means 22% discount followed by 19% discount.
Therefore we have 100-22= 78 and 100-19=81.
The final price would be 0.78*0.81=0.6318
Therefore discount would be
1 - 0.6318=0.3682
Hence, percentage discount would be 0.3682*100%=36.82%.
For manufacturer B 25/14 chian discount means 25% discount followed by 14% discount. So we have 100-25=75% and 100-14= 86%
Final price would be 0.86*.75=0.645.
Discount= 1 - 0.645= 0.355.
Percentage discount would be 0.355*100%=35.5%.
Answer:
Step-by-step explanation:
Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.
If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.
If you are imposing the x=-9 then, the problem would be set up like this:
=-9-3(-9)+5
=-9-(-27)+5
=18+5
=23
