Answer:
Sorry I dont kno :(
Step-by-step explanation:
Answer:
Given that they know the law I think 82.93% of drivers obey this law
To solve this equation, we will need to isolate y, the variable. These are the steps that follow:
1. Add 0.3y to each side.
2. Subtract 21.3 from each side.
3. Divide both sides by 5.4y.
Try and figure it out yourself! If you have trouble...
The answer is y = -8.5
Let
x--------> the number of minutes
y-------> the total liters of water sold
we know that
y=150x
Divide 7,500 by 150
=(7,500/150)=50 minutes
<u>Check</u>
For x=50 minutes
Find the value of y
y=150*(50)=7,500 liters of water sold------> is ok
<u>Find the domain</u>
The domain will be the interval------> [0,50] minutes
<u>Find the range</u>
The range will be the interval------> [0,7,500] liters of water sold
