Answer:
8.9
Step-by-step explanation:
1. DE:BC=AD:AB
2. AD=AB+BD, but according to the conditions AB=5, then
AD=5+BD.
3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:
16:9=(5+BD):5;
BD=80/9 - 5≈3.9.
4. if AD=AB+BD, then AD=5+3,9=8,9
Answer:
Step-by-step explanation:
Let
y -----> the profit earned by the hot dog stand daily
x ----> the number of hot dogs sold
we know that
The linear equation that represent this problem is equal to
This is the equation of the line into slope intercept form
where
----> is the slope
---> is the y-intercept (cost of the day's supply)
