Answer:
Step-by-step explanation:
Proof:
Let
take logs in both sides
using log properties we have . We know that then
Taking derivatives with respect to x, we have:
Next we can move things around
Replacing z for as defined in the first line, we get
If he had to lower it by 25%, it currently weight 75% of its original weight so if we let w=original weight:
w(75/100)=30 multiply both sides by 100
75w=3000 divide both sides by 75
w=40
So the original weight of the luggage was 40 kilograms.
the x-intercept of the line 3x - 5y = 7. is (7/3,0)
